Docker

Docker is the world's leading container platform software. It has been available since 2013. Docker is a container runtime tool designed to make it easier to create, deploy, and run applications by using containers. Docker has drastically reduced the complexity of managing applications by containerizing them. It allows applications to use the same Linux kernel as the host OS, unlike VMs, which create a whole new OS with dedicated hardware. Docker containers can run both on Linux and Windows workloads. Docker containers have enabled huge efficiencies in the development of software, but require runtime tools such as Swarm or Kubernetes.
