Mastering Microservices with Java - Third Edition

By: Sourabh Sharma

Overview of this book

Microservices are key to designing scalable, easy-to-maintain applications. This latest edition of Mastering Microservices with Java, works on Java 11. It covers a wide range of exciting new developments in the world of microservices, including microservices patterns, interprocess communication with gRPC, and service orchestration. This book will help you understand how to implement microservice-based systems from scratch. You'll start off by understanding the core concepts and framework, before focusing on the high-level design of large software projects. You'll then use Spring Security to secure microservices and test them effectively using REST Java clients and other tools. You will also gain experience of using the Netflix OSS suite, comprising the API Gateway, service discovery and registration, and Circuit Breaker. Additionally, you'll be introduced to the best patterns, practices, and common principles of microservice design that will help you to understand how to troubleshoot and debug the issues faced during development. By the end of this book, you'll have learned how to build smaller, lighter, and faster services that can be implemented easily in a production environment.

Logging and the ELK Stack

Can you imagine debugging any issue without seeing a log on the production system? The simple answer is no, as it would be difficult to go back in time. Therefore, we need logging. Logs also give us warning signals about the system if they are designed and coded that way. Logging and log analysis is an important step for troubleshooting any issue, and also for throughput, capacity, and monitoring the health of the system. Therefore, having a very good logging platform and strategy will enable effective debugging. Logging is one of the most important key components of software development in the initial stages.

Microservices are generally deployed using image containers such as Docker that provide the log with commands that help you read the logs of services that are deployed inside containers. Docker and Docker Compose provide commands to stream the log...
