Overview of this book

Microservices are the latest "right" way of developing web applications. Microservices architecture has been gaining momentum over the past few years, but once you've started down the microservices path, you need to test and optimize the services. This book focuses on exploring various testing, monitoring, and optimization techniques for microservices. The book starts with the evolution of software architecture style, from monolithic to virtualized, to microservices architecture. Then you will explore methods to deploy microservices and various implementation patterns. With the help of a real-world example, you will understand how external APIs help product developers to focus on core competencies. After that, you will learn testing techniques, such as Unit Testing, Integration Testing, Functional Testing, and Load Testing. Next, you will explore performance testing tools, such as JMeter, and Gatling. Then, we deep dive into monitoring techniques and learn performance benchmarking of the various architectural components. For this, you will explore monitoring tools such as Appdynamics, Dynatrace, AWS CloudWatch, and Nagios. Finally, you will learn to identify, address, and report various performance issues related to microservices.

Anatomy of Microservice Decomposition Services

In Chapter 1, Software Architecture Patterns, we discussed the microservice architecture and its benefits and challenges. The microservice architecture approach is all about dividing a complex monolithic application into several different independent services, which run independently on several machines or cloud servers. In this chapter, we will discuss the anatomy of the microservice architecture and look at how to decompose a monolithic application into a number of processes.

This chapter will discuss microservices in detail, including how to use applications and services. We will also look at the decomposition of the microservice architecture on the basis of business capability and the domain and subdomain.

By the end of this chapter, you will understand how microservices are built and will be able to build your own. You will also...
