Overview of this book

Docker containers have revolutionized the software supply chain in small and big enterprises. Never before has a new technology so rapidly penetrated the top 500 enterprises worldwide. Companies that embrace containers and containerize their traditional mission-critical applications have reported savings of at least 50% in total maintenance cost and a reduction of 90% (or more) of the time required to deploy new versions of those applications. Furthermore they are benefitting from increased security just by using containers as opposed to running applications outside containers. This book starts from scratch, introducing you to Docker fundamentals and setting up an environment to work with it. Then we delve into concepts such as Docker containers, Docker images, Docker Compose, and so on. We will also cover the concepts of deployment, orchestration, networking, and security. Furthermore, we explain Docker functionalities on public clouds such as AWS. By the end of this book, you will have hands-on experience working with Docker containers and orchestrators such as SwarmKit and Kubernetes.

Chapter 6. Distributed Application Architecture

In the previous chapter, we learned how we can use Docker volumes to persist created or modified state, as well as share data between applications running in containers. We also learned how to work with events generated by the Docker daemon and clean up unused resources.

In this chapter, we introduce the concept of a distributed application architecture and discuss the various patterns and best practices that are required to run a distributed application successfully. Finally, we will discuss the additional requirements that need to be fulfilled to run such an application in production.

In this chapter, we will cover the following topics:

  • What is a distributed application architecture?
  • Patterns and best practices
  • Running in production

After finishing this chapter, you will be able to do the following:

  • Name at least four characteristics of a distributed application architecture
  • Name at least four patterns that need to be implemented for a production...
