Training program

Module 1Micronaut Fundamentals: Installation and First Services (CLI, Gradle, Injection)

Introduction to the Micronaut CLI for quickly generating a professional microservice project, Gradle or Maven build configuration with native profiles, exploration of the application context and compile-time dependency injection, development of a basic secured REST API, automated unit tests via Spock, practical exercises on a concrete e-commerce case, production of a first Docker-containerized deliverable ready for staging.

Module 2Micronaut Architecture: Reactive Components and State Management (RxJava, Mutiny)

Deep dive into Micronaut singleton and prototype beans for enterprise scaling, implementation of reactive streams with RxJava or Mutiny to handle large data volumes, creation of high-performance asynchronous services, error handling and automated retries, hands-on workshops on real-time event processing, integration of distributed Caffeine cache, development of a testable reactive module with trainer code review for certified skills.

Module 3Advanced Micronaut APIs: HTTP, gRPC, and Security (OAuth, JWT)

Design of hypermedia RESTful APIs with auto-generated OpenAPI/Swagger, transition to gRPC for ultra-fast microservice communications, securing endpoints via Micronaut Security annotations and JWT/OAuth2, inbound data validation with Hibernate Validator, attack simulations and hardening, practical projects on a fictional banking API, generation of interactive documentation and Postman integration tests for immediate professional deployments.

Module 4Micronaut Persistence and Messaging: NoSQL Databases, Kafka (R2DBC, Reactive Streams)

Connecting Micronaut to MongoDB or PostgreSQL via reactive Data JDBC and R2DBC, entity modeling with Micronaut Data for compiled queries, Kafka producer/consumer integration for enterprise asynchronous events, distributed transaction management with Saga pattern, hands-on exercises on scalable e-commerce data flows with persistence, Prometheus metrics monitoring, creation of a complete persistent service with backups and recovery for high availability.
