Docker

What is Docker?

Docker is designed to deliver user applications faster. With Docker, users can separate applications from infrastructure and treat infrastructure like a managed application. This allows users to:

• Ship code faster
• Test faster
• Deploy faster
• Shorten the cycle between writing code and running code

Docker Benefits

Docker helps achieve this by using operating-system-level virtualization instead of hardware virtualization. This makes it very lightweight and efficient. Some key benefits are:

• Portability – Applications can run on any infrastructure regardless of OS
• Standardization – Common tools and workflows for building and sharing images
• Lightweight – Small footprint and fast provisioning of environments
• Scalable – Easy to replicate and scale containers
• Secure – Isolation prevents processes from affecting other containers
