Practical Microservices

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>

Summary


In this chapter, we discussed CI and CD and understood what these terms are, why they are important in shipping fast, and how they perfectly match with microservice architecture. To move things fast, ship fast. Moving big chunks is always a painful and a bit risky. So, microservice breaks the release into many and makes them independent. So, any service's new version can be shipped at any time and reverted back any time. To match up with the speed, you need automatic tests on newly integrated code (CI) and the deployment pipeline (CD). We discussed some CI and CD tools available on the market, and then, we tried some examples with Jenkins, Maven, and Spring Boot technologies. We have also introduced the Docker concept and discussed how we can use it with our services.
