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

Summary


Migrating from a monolithic to a microservice architecture is always a hard task. Always start with baby steps. Try to take out those services that do not interact directly with the user. Keep an eye on your metrics machine, as well as the application-level metrics. Try to avoid any destructive statements on the database. Use new columns, and refer to the old columns as the dead columns in the database. You must use a domain expert to divide your application into different services with bounded contexts. If this separation isn't good enough and is improperly planned, this will make your microservices fairly complicated in the future. Monitoring and scaling are the next important tasks that we have to do, which we will discuss in the upcoming chapters.
