Docker

Docker is a set of platform-as-a-service products that use OS-level virtualization to deliver software in packages called containers.

Why use Docker?

• Consistency: Containers package up an application with all of its dependencies, ensuring it runs the same way in any environment.
• Isolation: Containers isolate applications from one another and from the underlying infrastructure.
• Portability: Docker containers can run on any machine that has Docker installed.

Docker is a foundational technology for microservices and is often managed at scale using kubernetes.
