Docker

Docker is a suite of Platform as a Service (PaaS) products that use operating system-level virtualization to package and deploy software in containers. These containers enable applications to run in isolation and efficiently in different environments. Docker offers both free and premium tiers. The underlying software that manages the containers is called the Docker Engine. Originally released in 2013, Docker is developed by Docker, Inc. It is a valuable tool for automating application deployment in lightweight containers. Containers are isolated from each other and contain their own software, libraries and configuration files. Since all containers use the same operating system kernel and do not emulate hardware, they consume fewer resources compared to virtual machines. They also have no boot process. This significantly increases the deployment speed of Docker containers.
