Docker

Docker is an open source container-based virtualization platform. It was launched in 2013 and is currently maintained by the Docker, Inc. Docker is widely used for deploying and running applications in a distributed way. It is available for Linux, Mac OS X, and Microsoft Windows.

Docker enables developers to develop, deploy, and run applications in isolated containers. This makes it easier for organizations to develop distributed applications and scale them quickly. Containers can be created from images, which are typically obtained from Docker repositories. These images provide a consistent environment with an optimized base operating system, allowing developers to deploy and run applications with fewer dependencies.

Notable features of Docker include:

– Deployment automation – Docker can be used to deploy and manage applications in a distributed and automated way
– Container-based virtualization – Docker allows for quick and easy deployment and remote management of applications
– Container Isolation – Also known as ‘extra security’, Docker ensures that applications containers run in isolated, secure environments
– Storage and Networking – Docker uses storage and networking services such as OverlayFS, libnetwork, and overlay networking.

Docker has become popular as an efficient and secure way of creating and managing distributed applications. It has been adopted by many organizations, including banks, government agencies, and technology companies.
