Introduction

Lightweight container technology is revolutionizing IT infrastructure environments, and Docker containers are the frontrunners in this new era of enterprise ready container platforms. With the easy portability that Docker affords, organizations have the freedom to build and manage applications and deploy them across multiple infrastructures. This greatly increases operational efficiency and developer productivity, allowing applications to be run seamlessly across one server or deployed across multiple servers.

Over 700 million Docker containers are in use today, with over 10000 companies adopting Docker technology. Docker currently represents 83% of all containers in use. Containers enable a developer to package up an application with all of the parts, dependencies and libraries it requires, and ship it out as one single package. In this way, the developer can be assured that the application will operate other Linux machines even when the customized settings on the machine differ from the one used to write and test the code on.
