Java and Microservices: Architecture, Development, and Deployment

This book is a comprehensive practical guide to designing, developing, and operating microservice systems in Java. Drawing on real-world experience in building high-load distributed applications, the author systematically covers all stages of the microservice lifecycle: from choosing an architectural style to monitoring the production environment.

Who is this book for?

• Java developers looking to master microservice architecture.
• Software architects designing distributed systems.
• DevOps engineers responsible for deploying and orchestrating services.
• Team leads and technical managers making architectural decisions.

What you will learn from this book:

• Core principles of microservice architecture and how it differs from a monolith.
• Designing service boundaries (Domain-Driven Design, bounded contexts).
• Creating RESTful and gRPC APIs using Spring Boot, Micronaut, and Quarkus.
• Inter-service communication: synchronous (HTTP, gRPC) and asynchronous (Kafka, RabbitMQ).
• Configuration management, service discovery (Consul, Eureka), and load balancing.
• Containerization with Docker and orchestration with Kubernetes (preparing manifests, deployment, scaling).
• Ensuring fault tolerance: circuit breaker, retry, bulkhead (Resilience4j).
• Monitoring, logging, and tracing (Prometheus, Grafana, ELK, Jaeger).
• Testing microservices: unit, integration, and contract testing (Spring Cloud Contract).
• Security: OAuth2, JWT, API Gateway (Spring Cloud Gateway, Kong).

Book features:

• All code examples are written in modern Java (17+) and ready to use.
• Step-by-step instructions for environment setup, building, and running.
• Real-world cases: from a simple two-service application to a complex system with dozens of microservices.
• Comparison of popular frameworks (Spring Boot vs Micronaut vs Quarkus) and tools.
• Ready-made templates for Dockerfile, docker-compose, and Kubernetes manifests.

This book will become your desktop reference when building microservice solutions. Whether you are starting your first microservice or migrating an existing monolith, you will find proven practices, ready-made templates, and a deep understanding of how to build reliable, scalable, and maintainable systems in Java.
