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.

Centralized monitoring

Monitoring is key when microservice-based systems are deployed on a production environment. You need a monitoring system in place that captures different metrics such as health services, request and response monitoring, circuit breakers, CPU/RAM/storage, hardware monitoring, security, and all different metrics.

We need a system that consistently sends all information, a collector that collects this information and makes it available for consumption, and a visualization tool that shows collected information in a meaningful way. You can also add a notification tool that generates alerts.

Spring Boot provides health data and other metrics using Spring Boot Actuator. Moreover, a micrometer is also included in Spring Boot 2's Actuator and is also back ported to older Spring Boot versions with the addition of dependencies. Micrometer is SLF4J of metrics,...
