Practical Microservices

Key Features

• Leverage the power of microservices to build a flexible and efficient system in Java
• See Docker and Spring Boot in practice to form easily deployable microservices
• Hands-on approach throughout the book in order to familiarize and grasp the details

Book Description

A microservice architecture helps you build your application as a suite of different services. This approach has been widely adopted as it helps to easily scale up your application with reduced dependencies. This way if a part of your application is corrupted, it can be fixed easily thereby eliminating the possibility of completely shutting down your software. This book will teach you how to leverage Java to build scalable microservices. You will learn the fundamentals of this architecture and how to efficiently implement it practically.

We start off with a brief introduction to the microservice architecture and how it fares with the other architectures. The book dives deep into essential microservice components and how to set up seamless communication between two microservice end points. You will create an effective data model and learn different ways to test and deploy a microservices. You will also learn the best way to migrate your software from a monolith to a microservice architecture.

Finishing off with monitoring, scaling and troubleshooting, this book will set a solid foundation for you to start implementing microservices.

What you will learn

• The role of a discovery service and externalized configuration in the overall architecture
• Use of message brokers for event driven microservices
• How to intermix data management strategies across components
• Implementing different types of tests in Spring Boot environment
• Applying CI to our microservices style architecture
• Walk through of monitoring and scaling the sample application
