Overview of this book

Imagine creating and testing Java EE applications on Apache Tomcat Server or Wildfly Application server in minutes along with deploying and managing Java applications swiftly. Sounds too good to be true? But you have a reason to cheer as such scenarios are only possible by leveraging Docker and Kubernetes. This book will start by introducing Docker and delve deep into its networking and persistent storage concepts. You will then proceed to learn how to refactor monolith application into separate services by building an application and then packaging it into Docker containers. Next, you will create an image containing Java Enterprise Application and later run it using Docker. Moving on, the book will focus on Kubernetes and its features and you will learn to deploy a Java application to Kubernetes using Maven and monitor a Java application in production. By the end of the book, you will get hands-on with some more advanced topics to further extend your knowledge about Docker and Kubernetes.

Benefits of using the cloud, Docker, and Kubernetes

Having an application deployed on a Kubernetes cluster has its advantages. It's fail resilient, scalable, and has efficient architecture. What's the difference between having your own infrastructure and using the cloud? Well, it comes down to couple of factors. First, it can be a significant cost reduction. For small services or applications, which could be shut down when not in use, the price of deploying applications in the cloud can be lower, due to lower hardware costs, there will be more effective usage of physical resources. You will not have to pay for the nodes that do not use the computing power or network bandwidth.

Having your own servers requires you to pay for the hardware, energy, and operating system software. Docker and Kubernetes are free of charge, even for commercial purposes; so, if you run it in...
