In this chapter, we've discussed the history of software development methodology, programming evolution, and DevOps tools. These methodologies and tools support a faster software delivery cycle. The microservices design also helps to produce continuous software updates. However, microservices increase the complexity of the management of an environment.

In Chapter 2, DevOps with Containers, we will describe the Docker container technology, which helps to compose microservice applications and manage them in a more efficient and automated way.
