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.

Identifying performance counters to test microservices

In the microservice architecture pattern, a distributed system runs on several different machines, where each service is a component or process of an enterprise application. Although using a microservice-based application has a lot of advantages, it can bring about major challenges as well. One such challenge includes how to monitor a distributed system; this is because each microservice is heterogeneous and independent in nature. This means that traditional monitoring approaches are not good enough.

Monitoring is a critical part of a microservice-based system. It involves knowing how to control it and to how make sure that software is reliable, available, and that it performs as expected. This isn't a particularly easy task.

As you may know, traditional APM tools that are suitable for monolithic applications are not...
