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.

Microservice chassis to handle cross-cutting concerns

In any new application development, you are often required to implement particular scenarios or services, such as cross-cutting concerns. You have to spend a significant amount of time implementing common cross-cutting concerns in the development of a new application. Let's have a look at the following cross-cutting concerns:

  • Build system and externalized configuration: We have to choose either a Maven or a Gradle-based system to compile, package, version, and resolve external dependencies. This will also deal with further external configurations, such as credentials, and the network locations of external services, including databases or message brokers.
  • Implement logging: Logging is also required for all services of a new application development. You have to configure a logging framework, such as Java, Log4j, Logj42...
