In an era where productivity, clarity, and architectural consistency are paramount, developers and architects alike are seeking smarter ways to deliver high quality software faster. From reducing boilerplate to minimizing duplication and staying in creative flow, the goal is clear: build better systems with less friction.

Vibe Coding is a game changing approach that transforms how we build software using natural language prompts to generate clean, structured code instead of writing it line by line. It accelerates delivery while aligning with architectural principles like separation of concerns, domain driven design (DDD), and modularity.

For Solution Architects, this means:

• Faster translation of business requirements into working code

• More consistent design patterns and layering

• The ability to prototype and validate models before full scale implementation

• Reduced effort in onboarding teams and enforcing standards across services

This blog is your practical guide to adopting Vibe Coding in your workflow. Whether you're a solution architect, backend engineer, or rapid prototyper, you'll learn how to go from idea to implementation faster, cleaner, and smarter.

🌐 What Is Vibe Coding?​

Vibe Coding is a modern development paradigm where you use natural language prompts to define software components from domain models to workflows allowing intelligent tools or assistants to generate the underlying code for you. Whether you're working locally or in the cloud, you describe what you want to build, and the assistant figures out how to wire it up.

Instead of writing every class, annotation, or configuration manually, you describe your intent in plain English:

“Create a Project entity with name, description, and a list of Task references.”

Your assistant responds with:

• Well structured entity classes with correct annotations

• Repositories, services, and controllers following clean architecture

• REST or async APIs

• DTOs, mappers, and validation logic

• Optional: state machines, Kafka integration, unit tests, and security setup

At its core, Vibe Coding is about expressing intent, modeling domain logic, and scaffolding reliable code quickly all while aligning with best practices like Domain Driven Design, modularity, and separation of concerns.

For solution architects, Vibe Coding enables:

• Faster architectural modeling during early design phases

• Rapid iteration with business stakeholders

• Code consistency across services (regardless of team size)

• Governance and reuse via reusable prompt patterns and shared vocabularies

This isn’t just about generating code it’s about evolving software architecture from a conversation, and letting machines handle the heavy lifting so teams can focus on design, behavior, and business value.

⚙️ Why It Matters​

Let’s be honest software development involves a lot of repetition:

• Defining boilerplate CRUD layers

• Wiring relationships in ORM

• Setting up REST endpoints

• Mapping enums, DTOs, and validation rules

• Integrating workflows (Kafka, state machines, etc.)

• Even experienced developers spend valuable hours writing this scaffolding.

With Vibe Coding, you:

✅ Eliminate repetitive tasks

✅ Express ideas with clarity

✅ Maintain DDD compliant architecture

✅ Ship features faster

🛠 How to Apply Vibe Coding Practically​

Here’s a step by step breakdown of how to use Vibe Coding in real projects:

🔹 Step 1: Express the Domain Clearly​

Start with a clear prompt that outlines the structure and intent.

Example: "Create an Invoice entity with amount, dueDate, and a many to one relationship to Customer. Add an enum InvoiceStatus with PENDING, PAID, OVERDUE."

The goal is to describe the domain logic as if you're explaining it to a teammate the assistant then turns that into code.

🔹 Step 2: Review the Output and Iterate​

Once the assistant generates the initial code:

• Inspect the generated entities for structure and accuracy

• Adjust prompts to refine edge cases (e.g., "Make amount non null and validated")

• Extend with prompts like:

"Add a controller for Invoice that supports search by status."

Each prompt is a building block think of it as coding by conversation.

🔹 Step 3: Orchestrate Workflows​

You can go beyond simple models and describe logic flows and state transitions.

Prompt: “Set up a state machine for Document with states DRAFT, REVIEW, PUBLISHED, and transitions via submit, approve, publish.”

The assistant can generate:

• Enum for states

• Enum for events

• Spring StateMachine config

• Optional Kafka or REST triggers

This brings business workflows into your codebase without manual wiring.

🔹 Step 4: Stay in Control​

Even though you're coding with natural language, you're still in charge:

• You can enforce architectural boundaries (e.g., clean architecture, hexagonal design)

• You can combine generated code with handcrafted logic

• You decide where generation stops and custom logic begins

Vibe Coding is augmentative, not automatic.

💡 Real World Scenarios with Vibe Coding (Java 25, Cloud-Native, and Reactive)​

🔒 Best Practices for Vibe Coding​

1. Be Specific → "Make email unique" is better than "Add email"

2. Think in Behavior → Describe actions, not just fields: "Lock document after upload"

3. Use Enums & Relationships Wisely → Let the assistant handle JPA mappings

4. Modular Prompts → Break large systems into prompt driven modules

5. Code Review Is Still Key → Always validate and refine the generated code

🎯 The Bottom Line​

Vibe Coding bridges the gap between vision and implementation. It’s a practical evolution in software development that lets you:

• Build faster

• Think clearer

• Maintain quality

• Collaborate better

No more scaffolding fatigue. No more wiring loops. Just you, your domain logic, and the power to generate exactly what you need.

✍️ Final Thought​

We’re entering a new age where natural language becomes the new programming interface. Whether you're coding solo, prototyping a startup, or building enterprise systems — Vibe Coding keeps you in the flow.

👉 Start coding smarter today.​

Describe it. Refine it. Ship it.

Java is not just keeping up with the cloud native movement — it’s leading it. With the release of Java 25, the language has matured into an incredibly modern, efficient, and developer friendly platform for building distributed, containerized, and serverless applications.

☁️ What is “Cloud Native Java 25”?​

Cloud Native Java 25 is the practice of using Java version 25 to build applications tailored for cloud-native platforms such as:

• Docker and Kubernetes

• Serverless environments like AWS Lambda

• CI/CD pipelines

• Observability tools (Prometheus, OpenTelemetry)

• Elastic scaling environments

It means leveraging Java 25's capabilities to build apps that are scalable, portable, and maintainable.

🔥 Key Features in Java 25 for Cloud Native Development​

🧵 Virtual Threads (Project Loom)​

Java 25 brings virtual threads to the mainstream, allowing developers to write simple, readable code that can scale to handle thousands of concurrent requests:

try (var scope = StructuredTaskScope.open()) {
    Future<String> user = scope.fork(() -> getUserData());
    Future<String> profile = scope.fork(() -> getUserProfile());
    scope.join();
}

Why it matters: Great for APIs, microservices, and reactive backends without using complex frameworks.

⚛️ Reactive Programming (Still Relevant)​

While virtual threads simplify blocking I/O, reactive programming still shines for streaming, backpressure, and event driven architectures.

Flux<String> data = WebClient.create()
    .get()
    .uri("/events")
    .retrieve()
    .bodyToFlux(String.class);

Use both: Virtual threads for simplicity, reactive for high throughput.

📄 Records for Lightweight Data Models​

Records allow you to write simple data classes without boilerplate:

public record User(String id, String name, String email) {}

❄️ Pattern Matching and Sealed Types​

Java 25 enhances pattern matching and sealed types for safe and expressive modeling:

sealed interface Command permits Start, Stop {}
record Start() implements Command {}
record Stop() implements Command {}

void handle(Command cmd) {
    switch (cmd) {
        case Start s -> startApp();
        case Stop s  -> stopApp();
    }
}

🛠️ Foreign Function & Memory API (FFM)​

Interact with native code efficiently, without JNI:

try (Arena arena = Arena.ofConfined()) {
MemorySegment mem = arena.allocate(100);
// Use native memory here
}

Great for: ML inference, image processing, or calling native C libraries.

⏰ Project CRaC: Coordinated Restore at Checkpoint​

Experimental but powerful, CRaC enables fast startup via snapshots of the JVM:

Use case: Minimize cold starts in serverless or FaaS deployments.

🔍 Observability & Instrumentation​

Java 25 integrates well with cloud-native monitoring:

• OpenTelemetry SDKs for distributed tracing

• Micrometer for metrics

• Structured logging (JSON-ready)

Tooling: Auto-instrument with Java agents or inject via build tools.

🪜 Scoped Values (Better than ThreadLocal)​

Replace ThreadLocal for safer, more efficient context passing:

ScopedValue.runWhere(CONTEXT, "tenant42", () -> processRequest());

⚡ GraalVM and Native Image​

Java 25 apps can be compiled to native binaries for:

• Fast startup

• Reduced memory

• Serverless workloads

native-image --no-fallback -cp myapp.jar

🏢 Cloud Native Java 25: Starter Stack​

🧰 Final Thoughts​

Java 25 is not just another version — it’s a landmark for building cloud-native, efficient, and developer friendly applications in 2025 and beyond.

Whether you're deploying to Kubernetes, building serverless functions, or writing reactive data services, Java 25 has the modern tooling and runtime capabilities you need.

Modern backend systems demand reactive, scalable, and maintainable architectures especially for event driven workflows like document processing, user provisioning, or IoT orchestration. In this blog post, we’ll explore how to build a non blocking, production ready Spring StateMachine using Java 21, Spring Boot 3.3+, and Project Reactor. We'll follow architectural standards, observability best practices, and layer in a moderately complex real world example.

✨ Why Non-Blocking State Machines Matter​

A State Machine models the behavior of a system by defining possible states, events, and transitions. Using a non blocking (reactive) implementation brings huge benefits:

• Improved scalability: Threads aren’t blocked, allowing efficient resource usage

• Better responsiveness: Especially under high concurrency or I/O load

• Clean workflow orchestration: Explicitly model and track business state transitions

• Excellent integration: With Kafka, WebFlux, and Micrometer

🎓 Theory Refresher: What is a Finite State Machine (FSM)?​

A Finite State Machine (FSM) consists of:​

• A finite set of states

• A set of events that trigger transitions

• Transition functions that define valid state changes

• Optional entry/exit actions per state

FSMs are ideal for modeling lifecycle workflows like:​

• Order processing

• User registration

• Document approval

• IoT device management

In Spring StateMachine, FSM concepts are implemented with strong typing, clear configuration, and extensible action/guard hooks.

🔄 Architectural Patterns & Principles​

Below is a detailed table of architectural best practices and how they apply to Spring StateMachine:

🧱 Configuration Example​

State & Event Enums​

public enum DocState {
    NEW, VALIDATING, PROCESSING, REVIEW_PENDING, APPROVED, FAILED
}

public enum DocEvent {
    VALIDATE, PROCESS, SEND_FOR_REVIEW, APPROVE, FAIL
}

State Machine Configuration​

First, define separate Action classes for clarity and reuse:

@Component
public class ValidateAction implements Action<DocState, DocEvent> {
    public void execute(StateContext<DocState, DocEvent> context) {
        System.out.println("[Action] Validating document " + context.getStateMachine().getId());
    }
}

@Component
public class ProcessAction implements Action<DocState, DocEvent> {
    public void execute(StateContext<DocState, DocEvent> context) {
        System.out.println("[Action] Processing document " + context.getStateMachine().getId());
    }
}

@Component
public class ApproveAction implements Action<DocState, DocEvent> {
    public void execute(StateContext<DocState, DocEvent> context) {
        System.out.println("[Action] Approving document " + context.getStateMachine().getId());
    }
}

Now, wire them into your state machine configuration:java @Configuration

@Configuration
@EnableStateMachineFactory
@RequiredArgsConstructor
public class DocumentStateMachineConfig extends EnumStateMachineConfigurerAdapter<DocState, DocEvent> {
    private final ValidateAction validateAction;
    private final ProcessAction processAction;
    private final ApproveAction approveAction;

    @Override
    public void configure(StateMachineStateConfigurer<DocState, DocEvent> states) throws Exception {
        states.withStates()
                .initial(DocState.NEW)
                .state(DocState.VALIDATING)
                .state(DocState.PROCESSING)
                .state(DocState.REVIEW_PENDING)
                .end(DocState.APPROVED)
                .end(DocState.FAILED);
    }

    @Override
    public void configure(StateMachineTransitionConfigurer<DocState, DocEvent> transitions) throws Exception {
        transitions.withExternal().source(DocState.NEW).target(DocState.VALIDATING).event(DocEvent.VALIDATE).action(validateAction)
                .and()
                .withExternal().source(DocState.VALIDATING).target(DocState.PROCESSING).event(DocEvent.PROCESS).action(processAction)
                .and()
                .withExternal().source(DocState.PROCESSING).target(DocState.REVIEW_PENDING).event(DocEvent.SEND_FOR_REVIEW)
                .and()
                .withExternal().source(DocState.REVIEW_PENDING).target(DocState.APPROVED).event(DocEvent.APPROVE).action(approveAction)
                .and()
                .withExternal().source(DocState.VALIDATING).target(DocState.FAILED).event(DocEvent.FAIL)
                .and()
                .withExternal().source(DocState.PROCESSING).target(DocState.FAILED).event(DocEvent.FAIL);
    }

    private Action<DocState, DocEvent> log(String message) {
        return context -> System.out.printf("[Action] %s for doc: %s\n", message, context.getStateMachine().getId());
    }
}

⚙️ Running a Reactive State Machine​

@Service
public class DocumentWorkflowService {

    private final StateMachineFactory<DocState, DocEvent> factory;

    public DocumentWorkflowService(StateMachineFactory<DocState, DocEvent> factory) {
        this.factory = factory;
    }

    public void runWorkflow(String docId) {
        var sm = factory.getStateMachine(docId);
        sm.startReactively()
                .then(sm.sendEvent(Mono.just(MessageBuilder.withPayload(DocEvent.VALIDATE).build())))
                .then(sm.sendEvent(Mono.just(MessageBuilder.withPayload(DocEvent.PROCESS).build())))
                .then(sm.sendEvent(Mono.just(MessageBuilder.withPayload(DocEvent.SEND_FOR_REVIEW).build())))
                .then(sm.sendEvent(Mono.just(MessageBuilder.withPayload(DocEvent.APPROVE).build())))
                .then(sm.stopReactively())
                .subscribe();
    }
}

❗ Handling Errors in Actions and Ensuring Transitions​

In a robust state machine, handling exceptions within Action classes is critical to avoid broken workflows or silent failures.

🔒 Safe Action Execution Pattern​

You should catch exceptions within your Action class to prevent the state machine from halting unexpectedly:

@Component
public class ValidateAction implements Action<DocState, DocEvent> {
    public void execute(StateContext<DocState, DocEvent> context) {
        try {
            // Perform validation logic
            System.out.println("[Action] Validating " + context.getStateMachine().getId());
        } catch (Exception ex) {
            context.getExtendedState().getVariables().put("error", ex.getMessage());
            context.getStateMachine().sendEvent(DocEvent.FAIL);  // Trigger failure transition
        }
    }
}

🚨 Configure Error Transitions​

Make sure to define fallback transitions that catch these programmatic failures and move the machine to a safe state:

.withExternal()
  .source(DocState.VALIDATING)
  .target(DocState.FAILED)
  .event(DocEvent.FAIL)
  .action(errorHandler)

Define an optional errorHandler to log or notify:

@Component
public class ErrorHandler implements Action<DocState, DocEvent> {
    public void execute(StateContext<DocState, DocEvent> context) {
        String reason = (String) context.getExtendedState().getVariables().get("error");
        System.err.println("Transitioned to FAILED due to: " + reason);
    }
}

🛡️ Global Error Listener (Optional)​

Catch unhandled exceptions:

@Override
public void configure(StateMachineConfigurationConfigurer<DocState, DocEvent> config) throws Exception {
    config.withConfiguration()
            .listener(new StateMachineListenerAdapter<>() {
                @Override
                public void stateMachineError(StateMachine<DocState, DocEvent> stateMachine, Exception exception) {
                    log.error("StateMachine encountered an error: ", exception);
                }
            });
}

📊 Observability and Kafka Integration​

Metric Listener with Micrometer​

@Bean
public StateMachineListener<DocState, DocEvent> metricListener(MeterRegistry registry) {
    return new StateMachineListenerAdapter<>() {
        @Override
        public void stateChanged(State<DocState, DocEvent> from, State<DocState, DocEvent> to) {
            registry.counter("doc_state_transition", "from", from.getId().name(), "to", to.getId().name()).increment();
        }
    };
}

Kafka Event Trigger​

@KafkaListener(topics = "doc.events")
public void handleEvent(String json) {
    DocEvent event = parse(json);
    String docId = extractId(json);

    var sm = factory.getStateMachine(docId);
    sm.startReactively()
            .then(sm.sendEvent(Mono.just(MessageBuilder.withPayload(event).build())))
            .subscribe();
}

🖼️ DOT Export for Visualization​

To visualize your state machine, use the StateMachineSerialisationUtils utility provided by Spring StateMachine. Make sure you include the dependency:

<dependency>
    <groupId>org.springframework.statemachine</groupId>
    <artifactId>spring-statemachine-kryo</artifactId>
</dependency>

Then export the DOT file like so:

String dot = StateMachineSerialisationUtils.toDot(stateMachine);
Files.writeString(Path.of("statemachine.dot"), dot);

Render via:

dot -Tpng statemachine.dot -o statemachine.png

📏 Additional Standards and Extensions​

🧩 State Persistence with Redis or DB​

@Bean
public StateMachinePersister<DocState, DocEvent, String> persister() {
    return new InMemoryStateMachinePersister<>(); // Replace with Redis or JPA-based implementation
}

Use:

persister.persist(stateMachine, docId);
persister.restore(stateMachine, docId);

📉 Real Time Dashboards (Prometheus + Grafana)​

sum by (from, to) (rate(doc_state_transition[5m]))

🧪 Testing with Spring Test Plan​

@Test
void shouldTransitionFromNewToValidating() throws Exception {
    StateMachine<DocState, DocEvent> machine = factory.getStateMachine();
    machine.startReactively().block();
    boolean result = machine.sendEvent(Mono.just(MessageBuilder.withPayload(DocEvent.VALIDATE).build())).block();
    assertThat(machine.getState().getId()).isEqualTo(DocState.VALIDATING);
}

📐 FAQ: Best Practices​

Why emphasize external transitions? Easier to test and debug.

Why stateless machines? More scalable and testable.

Separate actions/guards? Yes — improves traceability and reuse.

Visualize workflows? Use DOT export + Graphviz.

Manage large flows? Use nested or orthogonal states.

State machines are widely used to model workflows, business processes, and system behavior in software engineering. But when used across large systems or microservices, the lack of transformation standards often leads to inconsistent transitions, duplicated logic, and hard to debug failures.

In this blog post, we'll explore how to define State Machine Transformation Standards – a practical approach to improving structure, traceability, and maintainability in systems using state machines.

Why Do We Need Transformation Standards?​

State machines are inherently about transitions — from one state to another based on an event. However, in real-world systems:

• Events come from multiple sources (UI, APIs, Kafka, batch jobs)

• The same state machine can be triggered in different contexts

• Transition logic often mixes with transformation logic

Without standards:​

• Event-to-state mapping becomes inconsistent

• Error handling differs across modules

• Reuse becomes difficult

With standards:​

• All transitions follow a common contract

• Developers know where to find transformation logic

• Testing becomes deterministic

Core Concepts of State Machine Transformation Standards​

• We'll define a layered architecture that separates:

• External Events (e.g., JSON messages, HTTP requests)

• Transformation Layer (mapping input to internal events)

• Internal State Machine (defined states, events, guards, actions)

• Post-Processing (e.g., publishing, notifications, logging)

+---------------------+
| External Event (JSON)|
+----------+----------+
           |
           v
+---------------------+
| EventTransformer     |
| Converts to          |
| Internal Event Enum  |
+----------+----------+
           |
           v
+---------------------+
| StateMachineService  |
| Applies transition   |
| Logs state change    |
+----------+----------+
           |
           v
+---------------------+
| Post Processor       |
| (Notify, Log, Save)  |
+---------------------+

Naming Conventions for States and Events​

State Naming (Enum):​

Use ALL_CAPS with action-driven semantics:​

• WAITING_FOR_VALIDATION

• VALIDATED

• REJECTED

• PROCESSING

Event Naming (Enum):​

Use PAST_TENSE or clear action phrases:​

• VALIDATION_SUCCEEDED

• VALIDATION_FAILED

• DOCUMENT_RECEIVED

• PROCESS_COMPLETED

The Event Transformer Standard​

This is a key part of the pattern. The EventTransformer receives raw input (e.g., from Kafka or REST) and maps it to a known event enum:

public interface EventTransformer {
    ScenarioEvent transform(Object externalEvent);
}

public class KafkaDocumentEventTransformer implements EventTransformer {
    @Override
    public ScenarioEvent transform(Object externalEvent) {
        if (externalEvent instanceof ValidationSuccessMessage) {
            return ScenarioEvent.VALIDATION_SUCCEEDED;
        }
        throw new IllegalArgumentException("Unknown event");
    }
}

Handling Standard Events: NEXT, FAIL, SKIP, RETRY​

In standardized workflows, having a common set of generic events improves clarity and reusability across different state machines. Four particularly useful event types are:

• NEXT: A neutral transition to the next logical state (often from a task completion)

• FAIL: Indicates a failure that should move the process to a failure or error state

• SKIP: Skips a task or validation step and moves to a later state

• RETRY: Retries the current action or state without progressing

These events should be defined in a shared enum or interface and respected across all state machine configurations.

public enum CommonEvent {
    NEXT,
    FAIL,
    SKIP,
    RETRY
}

When combined with guards and actions, these events make workflows predictable and debuggable.

State Machine Configuration Example (Spring StateMachine)​

builder.configureStates()
       .withStates()
       .initial(ScenarioState.WAITING_FOR_VALIDATION)
       .state(ScenarioState.VALIDATED)
       .state(ScenarioState.REJECTED);

builder.configureTransitions()
       .withExternal()
       .source(ScenarioState.WAITING_FOR_VALIDATION)
       .target(ScenarioState.VALIDATED)
       .event(ScenarioEvent.VALIDATION_SUCCEEDED);

Logging and Auditing Standard​

• Every transition should be logged with:

• Previous State

• Triggering Event

• New State

• Timestamp

• Correlation ID (e.g., documentId or userId)

log.info("Transitioned from {} to {} on event {} [docId: {}]",
         previousState, newState, event, docId);

Testing Transformation and Transitions​

Unit test the EventTransformer separately from the StateMachine:

@Test
void testKafkaToEventMapping() {
    ScenarioEvent event = transformer.transform(new ValidationSuccessMessage());
    assertEquals(ScenarioEvent.VALIDATION_SUCCEEDED, event);
}

Also test transitions:

@Test
void testValidationTransition() {
    stateMachine.sendEvent(ScenarioEvent.VALIDATION_SUCCEEDED);
    assertEquals(ScenarioState.VALIDATED, stateMachine.getState().getId());
}

Real-World Use Case – Document Workflow Engine​

At oohm.io, we use this standard to model document processing workflows. Documents pass through states like UPLOADED, VALIDATING, VALIDATED, FAILED_VALIDATION, and ARCHIVED. Each incoming Kafka message is transformed into an internal event, which triggers transitions.

The benefits:

• Simplified debugging of failures

• Easier onboarding for new developers

• Predictable behavior across microservices

Conclusion​

Defining clear State Machine Transformation Standards allows teams to build complex workflows without chaos. By separating concerns, using naming conventions, and implementing a structured transformer layer, you create a predictable and maintainable system.

Whether you're working on document pipelines, payment systems, or approval flows — standards will keep your state machines under control.

In the age of microservices and polyglot development, it's common for teams to use different languages for different tasks Java for orchestration, Python for AI, and C# for enterprise system integration. To tie all this together, Apache Kafka shines as a powerful messaging backbone. In this blog post, we’ll explore how to build a multi-language worker architecture using Spring Boot and Kafka, with workers written in Java, Python, and C#.

Why Use Kafka with Multiple Language Workers?​

Kafka is a distributed message queue designed for high-throughput and decoupled communication. Using Kafka with multi-language workers allows you to:

• Scale task execution independently per language.

• Use the best language for each task.

• Decouple orchestration logic from implementation details.

• Add or remove workers without restarting the system.

Topics​

• task-submission: Receives tasks from orchestrator

• task-result: Publishes results from workers

Common Message Format​

All communication uses a shared JSON message schema:

{
  "jobId": "123e4567-e89b-12d3-a456-426614174000",
  "taskType": "DOC_CONVERT",
  "payload": {
    "source": "http://example.com/sample.docx",
    "outputFormat": "pdf"
  }
}

Spring Boot Orchestrator​

Dependencies (Maven)​

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
</dependency>

REST + Kafka Integration​

@RestController
@RequestMapping("/jobs")
public class JobController {

    private final KafkaTemplate<String, String> kafkaTemplate;
    private final ObjectMapper objectMapper = new ObjectMapper();

    public JobController(KafkaTemplate<String, String> kafkaTemplate) {
        this.kafkaTemplate = kafkaTemplate;
    }

    @PostMapping
    public ResponseEntity<String> submitJob(@RequestBody Map<String, Object> job) throws JsonProcessingException {
        String jobId = UUID.randomUUID().toString();
        job.put("jobId", jobId);
        String json = objectMapper.writeValueAsString(job);
        kafkaTemplate.send("task-submission", jobId, json);
        return ResponseEntity.ok("Job submitted: " + jobId);
    }

    @KafkaListener(topics = "task-result", groupId = "orchestrator")
    public void receiveResult(String message) {
        System.out.println("Received result: " + message);
    }
}

Java Worker Example​

@KafkaListener(topics = "task-submission", groupId = "java-worker")
public void consume(String message) throws JsonProcessingException {
    ObjectMapper mapper = new ObjectMapper();
    Map<String, Object> task = mapper.readValue(message, new TypeReference<>() {});
    // ... Process ...
    Map<String, Object> result = Map.of(
            "jobId", task.get("jobId"),
            "status", "done",
            "worker", "java"
    );
    kafkaTemplate.send("task-result", mapper.writeValueAsString(result));
}

Python Worker Example​

from kafka import KafkaConsumer, KafkaProducer
import json

consumer = KafkaConsumer('task-submission', bootstrap_servers='localhost:9092', group_id='py-worker')
producer = KafkaProducer(bootstrap_servers='localhost:9092', value_serializer=lambda v: json.dumps(v).encode())

for msg in consumer:
    task = json.loads(msg.value.decode())
    print("Python Worker got task:", task)

    result = {
        "jobId": task["jobId"],
        "status": "completed",
        "worker": "python"
    }
    producer.send("task-result", result)

C# Worker Example (.NET Core)​

using Confluent.Kafka;
using System.Text.Json;

var config = new ConsumerConfig { BootstrapServers = "localhost:9092", GroupId = "csharp-worker" };
var consumer = new ConsumerBuilder<Ignore, string>(config).Build();
var producer = new ProducerBuilder<Null, string>(new ProducerConfig { BootstrapServers = "localhost:9092" }).Build();

consumer.Subscribe("task-submission");

while (true)
{
    var consumeResult = consumer.Consume();
    var task = JsonSerializer.Deserialize<Dictionary<string, object>>(consumeResult.Message.Value);
    
    var result = new {
        jobId = task["jobId"],
        status = "done",
        worker = "csharp"
    };

    producer.Produce("task-result", new Message<Null, string> {
        Value = JsonSerializer.Serialize(result)
    });
}

Monitoring & Logging​

• Use Prometheus + Grafana to monitor worker throughput and failures.

• Add structured logs with jobId for end-to-end traceability.

Local Testing Tips​

• Use Docker to spin up Kafka quickly (e.g., Bitnami Kafka).

• Use test producers/consumers (kafka-console-producer, kafka-console-consumer) to verify topics.

• Use Postman or cURL to submit jobs via Spring Boot.

Benefits of This Architecture​

Conclusion​

This architecture empowers teams to build distributed, language-agnostic workflows powered by Kafka. By combining the orchestration strength of Spring Boot with the flexibility of multi-language workers, you can build scalable, fault-tolerant systems that grow with your needs.

In this blog post, we'll build a real-world application that combines Spring StateMachine, Apache Kafka, and CSV-based document ingestion to manage complex document lifecycles in a scalable and reactive way.

Use Case Overview​

You have a CSV file that contains many documents. Each row defines a document and an event to apply (e.g., START, COMPLETE). The system should:

1. Read the CSV file

2. Send a Kafka message for each row

3. Consume the Kafka message

4. Trigger a Spring StateMachine transition for the related document

5. Persist the updated document state

Sample CSV Format​

documentId,title,state,event
doc-001,Contract A,NEW,START
doc-002,Contract B,NEW,START
doc-003,Report C,PROCESSING,COMPLETE

Technologies Used​

• Java 17

• Spring Boot 3.x

• Spring StateMachine

• Spring Kafka

• Apache Commons CSV

• H2 Database

Enum Definitions​

public enum DocumentState {
    NEW, PROCESSING, COMPLETED, ERROR
}

public enum DocumentEvent {
    START, COMPLETE, FAIL
}

StateMachine Configuration​

@Configuration
@EnableStateMachineFactory
public class DocumentStateMachineConfig extends StateMachineConfigurerAdapter<DocumentState, DocumentEvent> {

    @Override
    public void configure(StateMachineTransitionConfigurer<DocumentState, DocumentEvent> transitions) throws Exception {
        transitions
                .withExternal().source(DocumentState.NEW).target(DocumentState.PROCESSING).event(DocumentEvent.START)
                .and()
                .withExternal().source(DocumentState.PROCESSING).target(DocumentState.COMPLETED).event(DocumentEvent.COMPLETE)
                .and()
                .withExternal().source(DocumentState.NEW).target(DocumentState.ERROR).event(DocumentEvent.FAIL);
    }
}

Document Entity​

@Entity
public class Document {

    @Id
    private String id;
    private String title;

    @Enumerated(EnumType.STRING)
    private DocumentState state;

    // Getters and Setters
}

Kafka Producer and CSV Processing​

@Component
public class CsvProcessor {

    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;

    public void processCSV(InputStream inputStream) throws IOException {
        try (BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
             CSVParser parser = CSVFormat.DEFAULT.withFirstRecordAsHeader().parse(reader)) {

            for (CSVRecord record : parser) {
                String documentId = record.get("documentId");
                String event = record.get("event");
                kafkaTemplate.send("document-events", documentId, event);
            }
        }
    }
}

REST Upload Endpoint​

@RestController
@RequestMapping("/api/documents")
public class DocumentUploadController {

    @Autowired
    private CsvProcessor csvProcessor;

    @PostMapping("/upload")
    public ResponseEntity<String> upload(@RequestParam("file") MultipartFile file) throws IOException {
        csvProcessor.processCSV(file.getInputStream());
        return ResponseEntity.ok("CSV processed successfully");
    }
}

Kafka Listener and State Transition​

@Component
public class DocumentEventListener {

    @Autowired
    private StateMachineFactory<DocumentState, DocumentEvent> stateMachineFactory;

    @Autowired
    private DocumentRepository documentRepository;

    @KafkaListener(topics = "document-events")
    public void onMessage(ConsumerRecord<String, String> record) {
        String docId = record.key();
        DocumentEvent event = DocumentEvent.valueOf(record.value());

        StateMachine<DocumentState, DocumentEvent> sm = stateMachineFactory.getStateMachine(docId);
        sm.start();
        sm.sendEvent(event);

        Document doc = documentRepository.findById(docId).orElseThrow();
        doc.setState(sm.getState().getId());
        documentRepository.save(doc);
    }
}

Document Repository​

public interface DocumentRepository extends JpaRepository<Document, String> {}

Final Thoughts​

This architecture provides:​

• Decoupled, event-driven state management

• Easily testable document lifecycles

• A scalable pattern for batch processing from CSVs

You can extend this with:​

• Retry transitions

• Error handling

• Audit logging

• UI feedback via WebSockets or REST polling

In this blog post, we'll walk through building a cloud-native Spring Boot application that runs on Amazon EKS (Elastic Kubernetes Service) and securely uploads files to an Amazon S3 bucket using IAM Roles for Service Accounts (IRSA). This allows your microservice to access AWS services like S3 without embedding credentials.

Why IRSA?​

Traditionally, applications used access key/secret pairs for AWS SDKs. In Kubernetes, this is insecure and hard to manage. IRSA allows you to:

• Grant fine-grained access to AWS resources
• Avoid storing AWS credentials in your app
• Rely on short-lived credentials provided by EKS

Overview​

Here's the architecture we'll implement:

1. Spring Boot app runs in EKS
2. The app uses AWS SDK v2
3. IRSA provides access to S3

Step 1: Create an IAM Policy for S3 Access​

Create a policy named S3UploadPolicy with permissions for your bucket:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:PutObject",
        "s3:GetObject"
      ],
      "Resource": "arn:aws:s3:::your-bucket-name/*"
    }
  ]
}

Step 2: Create an IAM Role for EKS​

Use eksctl to create a service account and bind it to the IAM role:

eksctl create iamserviceaccount \
--name s3-uploader-sa \
--namespace default \
--cluster your-cluster-name \
--attach-policy-arn arn:aws:iam::<ACCOUNT_ID>:policy/S3UploadPolicy \
--approve \
--override-existing-serviceaccounts

Step 3: Spring Boot Setup​

Add AWS SDK Dependency

<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>s3</artifactId>
</dependency>

Java Code to Upload to S3​

import software.amazon.awssdk.auth.credentials.DefaultCredentialsProvider;
import software.amazon.awssdk.core.sync.RequestBody;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;
import software.amazon.awssdk.services.s3.model.PutObjectRequest;

import java.io.InputStream;

@Service
public class S3Uploader {

    private final S3Client s3Client;

    public S3Uploader() {
        this.s3Client = S3Client.builder()
                .region(Region.EU_CENTRAL_1)
                .credentialsProvider(DefaultCredentialsProvider.create())
                .build();
    }

    public void uploadFile(String bucketName, String key, InputStream inputStream, long contentLength) {
        PutObjectRequest putRequest = PutObjectRequest.builder()
                .bucket(bucketName)
                .key(key)
                .build();

        s3Client.putObject(putRequest, RequestBody.fromInputStream(inputStream, contentLength));
    }
}

DefaultCredentialsProvider automatically picks up credentials from the environment, including those provided by IRSA in EKS.

Step 4: Kubernetes Deployment​

Define the Service Account (optional if created via eksctl):

apiVersion: v1
kind: ServiceAccount
metadata:
  name: s3-uploader-sa
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::<ACCOUNT_ID>:role/<IRSA_ROLE_NAME>

apiVersion: apps/v1
kind: Deployment
metadata:
  name: s3-upload-microservice
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      app: s3-upload-microservice
  template:
    metadata:
      labels:
        app: s3-upload-microservice
    spec:
      serviceAccountName: s3-uploader-sa
      containers:
        - name: app
          image: 123456789012.dkr.ecr.eu-central-1.amazonaws.com/s3-uploader:latest
          ports:
            - containerPort: 8080

Final Thoughts​

You now have a secure, cloud-native Spring Boot application that uploads to S3 using best practices with AWS and Kubernetes. IRSA removes the need for credentials in your code and aligns perfectly with GitOps, DevSecOps, and Zero Trust principles.

Let your microservices speak AWS securely — the cloud-native way!

When deploying applications in an Amazon EKS (Elastic Kubernetes Service) environment, securing them with SSL/TLS is essential to protect sensitive data and ensure secure communication. One of the most popular and free methods to obtain TLS certificates is through Let’s Encrypt. This guide walks you through the process of setting up TLS certificates on an EKS cluster using Cert-Manager and NGINX Ingress Controller.

Prerequisites​

Before starting, ensure you have the following:

• An EKS Cluster set up with worker nodes.
• kubectl configured to access your cluster.
• A registered domain name pointing to the EKS load balancer.
• NGINX Ingress Controller installed on the cluster.

Step 1: Install Cert-Manager​

Cert-Manager automates the management of TLS certificates within Kubernetes.

Install Cert-Manager​

Run the following command to apply the official Cert-Manager manifests:

kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.12.2/cert-manager.yaml

Verify the pods:

kubectl get pods --namespace cert-manager

You should see the following pods running:

• cert-manager

• cert-manager-cainjector

• cert-manager-webhook

Step 2: Create a ClusterIssuer​

A ClusterIssuer is a resource in Kubernetes that defines how Cert-Manager should obtain certificates. We’ll create one using Let’s Encrypt’s production endpoint.

ClusterIssuer YAML File:​

Create a file named letsencrypt-cluster-issuer.yaml with the following content:

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-prod
spec:
  acme:
    server: https://acme-v02.api.letsencrypt.org/directory
    email: your.email@example.com  # Change this to your email
    privateKeySecretRef:
      name: letsencrypt-prod-private-key
    solvers:
      - http01:
          ingress:
            class: nginx

Apply the YAML:

kubectl apply -f letsencrypt-cluster-issuer.yaml

Verify that the ClusterIssuer is created successfully:

kubectl get clusterissuer

Step 3: Create an Ingress Resource with TLS​

The Ingress resource will route external traffic to services within the cluster and configure TLS.

Ingress YAML File:​

Create a file named ingress.yaml with the following content:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-app-ingress
  namespace: default
  annotations:
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
spec:
  ingressClassName: nginx
  rules:
    - host: yourdomain.com  # Replace with your domain
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: my-app-service
                port:
                  number: 80
  tls:
    - hosts:
        - yourdomain.com
      secretName: my-app-tls

Apply the YAML:

kubectl apply -f ingress.yaml

Step 4: Verify the TLS Certificate​

Check the status of the certificate request:

kubectl describe certificate my-app-tls

You should see a message indicating that the certificate was successfully issued. Cert-Manager will create a Kubernetes Secret named my-app-tls that contains the TLS certificate and key.

List the secrets to verify:

kubectl get secrets

You should see my-app-tls listed.

Step 5: Test the HTTPS Connection​

Once the certificate is issued, test the connection:

1. Open a browser and navigate to https://yourdomain.com.

2. Verify that the connection is secure by checking for a valid TLS certificate.

Troubleshooting Tips:

• Ensure the domain correctly resolves to the EKS load balancer.

• Check for errors in the Cert-Manager logs using:

kubectl logs -n cert-manager -l app=cert-manager

Step 6: Renewing and Managing Certificates​

Let’s Encrypt certificates are valid for 90 days. Cert-Manager automatically renews them before expiry.

To check if the renewal is working:

kubectl get certificates

Look for the renewal time and ensure it’s set before the expiration date.

Step 7: Clean Up (Optional)​

If you want to remove the configurations:

kubectl delete -f ingress.yaml
kubectl delete -f letsencrypt-cluster-issuer.yaml
kubectl delete -f https://github.com/cert-manager/cert-manager/releases/download/v1.12.2/cert-manager.yaml

Conclusion​

Congratulations! You have successfully secured your applications on an EKS cluster using Let’s Encrypt certificates. With the help of Cert-Manager, you can automate certificate issuance, management, and renewal, ensuring your applications always maintain secure communications. By following this guide, you have taken a significant step towards enhancing the security posture of your Kubernetes environment.

In modern microservices architecture, service discovery and service mesh are two essential concepts that help manage the complexity of distributed systems. In this blog post, we will show you how to integrate Spring Boot Eureka Service Discovery with OCI (Oracle Cloud Infrastructure) Service Mesh to leverage the benefits of both systems.

What is Service Discovery and Service Mesh?​

• Service Discovery: This is a mechanism that allows services to dynamically register and discover each other. Spring Boot provides Eureka, a service discovery tool that helps minimize network latency and increase fault tolerance.
• Service Mesh: A service mesh like OCI Service Mesh provides an infrastructure to manage the communication traffic between microservices. It offers features such as load balancing, service-to-service authentication, and monitoring.

Steps to Integration​

1. Setup and Configuration of OCI Service Mesh​

The first step is to create and configure OCI Service Mesh resources.

• Create Mesh and Virtual Services: Log in to the OCI dashboard and create a new mesh resource. Define virtual services and virtual service routes that correspond to your microservices.
• Deployment of Sidecar Proxies: OCI Service Mesh uses sidecar proxies that need to be deployed in your microservices pods.

2. Configuration of Spring Boot Eureka​

Eureka Server Configuration​

Create a Spring Boot application for the Eureka server. Configure application.yml as follows:

server:
  port: 8761

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
  instance:
    hostname: localhost
  server:
    enable-self-preservation: false

Eureka Client Configuration​

Configure your Spring Boot microservices as Eureka clients. Add the following configuration to application.yml:

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
  instance:
    prefer-ip-address: true

3. Integration of Both Systems​

To integrate Spring Boot Eureka and OCI Service Mesh, there are two approaches:

• Dual Registration: Register your services with both Eureka and OCI Service Mesh.
• Bridge Solution: Create a bridge service that syncs information from Eureka to OCI Service Mesh.

Example Configuration​

Creating Mesh Resources in OCI​

• Create Mesh and Virtual Services: Navigate to the OCI dashboard and create a new mesh resource. Define the necessary virtual services and routes.

Deployment with Sidecar Proxy​

Update your Kubernetes deployment YAML files to add sidecar proxies. An example snippet might look like this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-service
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-service
  template:
    metadata:
      labels:
        app: my-service
    spec:
      containers:
        - name: my-service-container
          image: my-service-image
          ports:
            - containerPort: 8080
        - name: istio-proxy
          image: istio/proxyv2
          args:
            - proxy
            - sidecar
            - --configPath
            - /etc/istio/proxy
            - --binaryPath
            - /usr/local/bin/envoy
            - --serviceCluster
            - my-service
          env:
            - name: POD_NAME
              valueFrom:
                fieldRef:
                  fieldPath: metadata.name
            - name: POD_NAMESPACE
              valueFrom:
                fieldRef:
                  fieldPath: metadata.namespace
            - name: INSTANCE_IP
              valueFrom:
                fieldRef:
                  fieldPath: status.podIP
            - name: HOST_IP
              valueFrom:
                fieldRef:
                  fieldPath: status.hostIP

Conclusion​

Integrating Spring Boot Eureka Service Discovery with OCI Service Mesh allows you to leverage the benefits of both systems: dynamic service registration and discovery from Eureka, as well as the advanced communication and security features of OCI Service Mesh. Through careful planning and configuration of both systems, you can create a robust and scalable microservices architecture.

With these steps, you are ready to integrate Spring Boot Eureka and OCI Service Mesh into your microservices architecture. Good luck with the implementation!

The intersection of biotechnology and innovative design methodologies offers unparalleled opportunities to solve complex biological challenges. One such promising approach is Storytelling Collaborative Modeling, particularly when augmented by artificial intelligence (AI). This technique not only simplifies the conceptualization of sophisticated biotech processes like mRNA synthesis but also promotes a collaborative environment that bridges the gap between scientists, engineers, and other stakeholders.

The Power of Storytelling in Biotechnology:​

Storytelling has the unique capability to demystify complex scientific concepts, making them accessible and relatable. In biotechnological applications, especially in areas like mRNA synthesis, storytelling can help depict the intricate process of how mRNA is synthesized, processed, and utilized in protein production within cells. This narrative approach helps non-specialists and stakeholders grasp the essential details without needing deep technical expertise.

Collaborative Modeling in Biotech Design:​

In the realm of biotechnology, collaborative modeling involves multidisciplinary teams—including molecular biologists, bioinformatics specialists, and clinical researchers—coming together to build and refine models of biological processes. In the context of mRNA synthesis, these models might represent the transcription of DNA into mRNA, the translation of mRNA into proteins, or the therapeutic application of synthetic mRNA in vaccines.

Enhancing the Narrative with AI:​

AI can dramatically enhance storytelling collaborative modeling by automating data analysis, generating predictive models, and simulating outcomes. For mRNA synthesis, AI tools can model how modifications in the mRNA sequence could impact protein structure and function, provide insights into mRNA stability, and predict immune responses in therapeutic applications, such as in mRNA vaccines.

Example: mRNA Synthesis in Vaccine Development:​

Consider the development of an mRNA vaccine—a timely and pertinent application. The process starts with the design of an mRNA sequence that encodes for a viral protein. Storytelling can be used to narrate the journey of this mRNA from its synthesis to its delivery into human cells and subsequent protein production, which triggers an immune response.

AI enhances this narrative by simulating different scenarios, such as variations in the mRNA sequence or changes in the lipid nanoparticles used for delivery. These simulations help predict how these changes would affect the safety and efficacy of the vaccine, enabling more informed decision-making during the design phase.

Benefits of This Approach:​

• Enhanced Understanding: Complex biotechnological processes are explained in a simple, story-driven format that is easier for all stakeholders to understand.
• Improved Collaboration: Facilitates a cooperative environment where diverse teams can contribute insights, leading to more innovative outcomes.
• Faster Innovation: Accelerates the experimental phase with AI-driven predictions and simulations, reducing time-to-market for critical medical advancements.
• Effective Communication: Helps communicate technical details to regulatory bodies, non-specialist stakeholders, and the public, enhancing transparency and trust.

Incorporating Output Models in Storytelling Collaborative Modeling:​

A crucial component of leveraging AI in the narrative of mRNA synthesis is the creation and use of output models. These models serve as predictive tools that generate tangible outputs or predictions based on the input data and simulation parameters.
