Microservices: A Practical Guide

Microservices have many advantages: Efficiently implementing more features, bringing software into production faster, robustness and easy scalability are among them. But implementing a microservices architecture and selecting the necessary technologies are difficult challenges.This book shows microservices recipes that architects can customize and combine into a microservices menu. In this way, the implementation of microservices can be individually adapted to the requirements of the project.Eberhard Wolff introduces microservices, self-contained systems, micro- and macro-architecture and the migration to microservices. The second part shows the microservices recipes: Basic technologies such as Docker or PaaS, frontend integration with links, JavaScript or ESI (Edge Side Includes). This is followed by asynchronous microservices with Apache Kafka or REST / Atom. In the synchronous approaches, the book discusses REST with the Netflix stack, Consul, PaaS with Cloud Foundry, and Kubernetes. Finally, operations is discussed: Log Analysis with Elasticsearch and Kibana, Monitoring with Prometheus, and tracing with Zipkin.The second edition is based on the feedback about the first edition. All chapters have been clarified, updated and extended. A new chapter discusses services meshes, in particular Istio with an example application. The second edition has about 35 pages more than the first edition.For each recipe there are suggestions for variations and combinations. Readers can experience all technologies hands-on with a demo project on GitHub. The outlook picks up on the operation of microservices and also shows how the reader can start with microservices in concrete terms.The book provides the technical tools to implement a microservices architecture. Demo projects and suggestions for self-study will complete the book.
