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.

Introducing an API gateway

In our online bookshop application, we have several diverse clients such as mobile, desktop, and laptop. Consequently, we have to develop the native client for this application. Let's imagine there is an order details page that displays order information about a book, as well as the details of the customer who purchased it.

The following services are required in order to obtain such order details:

  • Order Service: This provides information about order details and order history
  • Account Service: This provides information about the customer
  • Book Service: This provides information about books and their availability in the product catalog
  • Shipping Service: This provides details about shipping ordered books
  • Note that the application may have many more services available

Suppose you choose to build an application with a monolithic software architecture...
