Learn to develop microservices using the latest open-source MicroProfile, Jakarta EE, and cloud-native deployment practices. This fully updated edition walks you through a complete cloud-native journey, from the first principles of cloud computing to a fully deployed, observable, and secure microservices-based e-commerce application running on Docker and Kubernetes.

You will learn how cloud-native architecture and the twelve-factor methodology shape modern application architecture. This book takes a hands-on approach in which you progressively apply every major MicroProfile specification, including externalized Config, Health probes, Metrics, Fault Tolerance patterns, distributed Telemetry, JWT-based security, type-safe REST Client communication, flexible GraphQL APIs, and event-driven Reactive Messaging with Apache Kafka. The final chapters of the book take your application to production: packaging services as OCI-compliant Docker images, deploying and scaling them on Kubernetes, and automating the entire pipeline with GitHub Actions CI/CD.

After reading this book, you will have the skills and confidence to design, build, secure, observe, and deploy cloud-native Java applications using industry-standard open specifications.

What You'll Learn

• Learn cloud-native app design for scalable, resilient Java microservices.
• Build microservices with MicroProfile, Jakarta EE, leveraging key specifications including OpenAPI, Config, and Health.
• Implement resilience patterns like retries, timeouts, circuit breakers, and secure microservices with JWT, REST Client, and GraphQL APIs.
• Implement monitoring using Metrics specifications and observability via MicroProfile Telemetry using LGTM stack: Loki, Grafana, Tempo, Mimir.
• Build loosely coupled APIs using Reactive Messaging on Kafka, and deploy microservices using Docker and Kubernetes.
