Turn the theory of distributed systems into production-ready code. This book walks you through building CinéTrack, a complete real-world microservices platform, one chapter at a time, from a single Spring Boot service to a resilient, observable, globally distributed system.

You'll build 34 chapters' worth of working code: REST and gRPC APIs, event-driven communication with Kafka, service discovery with Eureka, centralised configuration, Resilience4j circuit breakers, distributed tracing with

OpenTelemetry, CQRS, the transactional outbox pattern, sagas, OAuth2 with Spring Authorization Server, contract testing, Docker, Kubernetes, Istio service mesh, multi-tenancy, reactive programming with WebFlux and R2DBC,GraalVM native images, event sourcing, chaos engineering, and multi-region deployments with MirrorMaker2.

Each chapter builds on the last, and every concept is grounded in runnable code. You won't just read about circuit breakers. You'll watch one trip in WireMock tests. You won't just hear about the saga pattern. You'll implement one with compensating transactions against Testcontainers Postgres and Kafka.

By the end, you'll have done more than read about microservices. You'll have built them.
