Microservices for Java Developers

Chapter 1. Microservices for Java Developers

What Can You Expect from This Book?

This book is for Java developers and architects interested in developing microservices. We start the book with the high-level understanding and fundamental prerequisites that should be in place to be successful with a microservice architecture. Unfortunately, just using new technology doesn’t magically solve distributed systems problems. We take a look at some of the forces involved and what successful companies have done to make microservices work for them, including culture, organizational structure, and market pressures. Then we take a deep dive into a few Java frameworks for implementing microservices. The accompanying source-code repository can be found on GitHub. Once we have our hands dirty, we’ll come back up for air and discuss issues around deployment, clustering, failover, and how Docker and Kubernetes deliver solutions in these areas. Then we’ll go back into the details with some hands-on examples with Docker, Kubernetes, and NetflixOSS to demonstrate the power they bring for cloud-native, microservice architectures. We finish with thoughts on topics we cannot cover in this small book but are no less important, like configuration, logging, and continuous delivery.

Microservices are not a technology-only discussion. Implementations of microservices have roots in complex-adaptive theory, service design, technology evolution, domain-driven design, dependency thinking, promise theory, and ...
