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.

Gatling

Gatling is an open-source platform that was established for the purpose of testing load and performance. This software implements load testing over an application, meaning that you can determine the performance of various services while still focusing on the web application. With Gatling, you can create your own tests by using the Scala programming language. Although this language is not very well-known, tests that are developed with it are. Gatling has become quite popular over the last couple of years and is used by a significant number of developers and testers.

Gatling also provides a detailed dashboard that shows you the results of the tests that you have performed. Without making use of any added plugins, the system also generates a report of the results in HTML format. This report can be easily saved on the device for further use and analysis, or for metric comparisons...
