Practical Microservices

By: Umesh Ram Sharma

Overview of this book

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

Preface

High DevOps involvement


With so many environments in place, so many servers running in the platform, there is a need for DevOps guys to be available 24x7. If someone wants to release a service, they require a DevOps guys to build a release and deploy it. In monolithic, any release is a big thing, happening perhaps months. Any failure will bring the whole platform down and increase the downtime. So, DevOps guys are always required. There are two ways to handle this issue.

Use smart tools

With the use of smart tools such as Jenkins, Travis, Chef, and Puppet, with the inclusion of some custom scripts, you should completely automate deployments of microservices. One-button deployment should be implemented and deployed.

Use smart developers

Make your developer learn the DevOps work also. Developers are not supposed to understand the whole work of DevOps, but while migrating to a microservice architecture , a developer should come with the mindset of ownership of their microservice, and their ownership...
