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.

JMeter

JMeter was first developed by Stefano Mazzochi from Apache software. It was originally designed for the purpose of testing the Apache JServ Protocol (AJP) but was redesigned by Apache with an enhanced GUI and the ability to perform functional testing. It is now an open-source testing software that is made up of pure Java applications for the purpose of load and performance testing. It covers a wide variety of test categories, including functional, load, performance, and regression.

The protocols that JMeter supports include the following:

  • The web, including HTTP and HTTPS sites
  • Web services, such as SOAP/XML-RPC
  • Databases via JDBC drivers
  • Directories, such as LDAP
  • Messaging-oriented services via JMS
  • Services, such as POP3, IMAP, and SMTP
  • FTP services

With a simple GUI, JMeter can conduct load and performance tests and is completely platform-free, whether you are running...
