Docker shines compared to virtual machines when it comes to performance because containers share the host kernel and do not emulate a full operating system. However, Docker does impose performance costs. … If you need to get the best possible performance out of your server, you may want to avoid Docker.
What is docker in simple words?
In simple terms, Docker is a software platform that simplifies the process of building, running, managing and distributing applications. It does this by virtualizing the operating system of the computer on which it is installed and running.

What is Docker and how does it work?
Docker provides the ability to package and run an application in a loosely isolated environment called a container. The isolation and security allow you to run many containers simultaneously on a given host. … This means you can run more containers on a given hardware combination than if you were using virtual machines.
Is Docker easy to learn?
It’s not easy to set up an instance of a complex real-world Java application because you need many different things, Docker solves this problem by putting everything you need into a container and deploy wherever you want like on Linux, Mac, or Windows. … It’s written especially for Java developers.
How is Docker different than a VM?
From the image above, you can see each virtual machine has its guest operating system above the host operating system, which makes virtual machines heavy. While on the other hand, Docker containers share the host operating system, and that is why they are lightweight.
Is Docker going away?
