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>

Preface

Chapter 9. Monitoring and Scaling

Moving to microservice architecture from a monolithic application gives a number of benefits to the company, such as a smaller code base, fast shipping, adding new features quickly, easy to develop, easy to scale certain parts of application, and so on. However, with the growing use of microservice architecture, their complexity also increases. It becomes very challenging to know what is happening inside the system. The flowing of so many messages inside the system makes it hard to know the exact state of the system. Also, dynamic architectures and the auto-scale world makes things more complex. In this chapter, we will take a look at some of the key points to keep in mind for monitoring and scaling microservices.

This chapter covers the following topics:

  • Principles in monitoring a microservices system
  • Principles in scaling a microservices system
  • Practical options for both monitoring and scaling microservices
