Docker Overview :

Docker is an open platform for developing, shipping, and running applications. It provides the ability to package and run an application in a loosely isolated environment called a container.

The isolation and security allows us to run many containers simultaneously on a given host. Containers are lightweight and contain everything needed to run the application, so we do not need to rely on what is currently installed on the host.

Docker can be used for :

• Fast and consistent delivery of applications.
• Responsive deployment and scaling.
• Running more workloads on the same hardware.
