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.

Building microservices

In this section, we will discuss how to build a microservice-based application using the same online bookshop example as in the previous sections. Our application has the following four modules:

  • Customer Account Management
  • Order Management
  • Book Inventory Management
  • Shipping Management

I will create a microservice for each of these modules. The following microservices correspond to the application modules:

  • Customer Account Management → Account Service
  • Order Management → Order Service
  • Book Inventory Management → Book Service
  • Shipping Management → Shipping Service

The following diagram shows the architecture of this online bookshop application:

As you can see in the preceding diagram, we have four core microservices in this application. This architecture also has two more services: an API Gateway and the Shopfront UI web application...
