Docker is a user-friendly platform that allows fast storage, delivery and efficient management of applications inside containers. In simple words, it is an open-source project which automates application implementation in containers of software. Docker enables the design, deployment and execution of applications with containers and these containers in turn, allow developers to bundle an application with all the required parts, including libraries and other dependencies. The bundle is then shipped as one package.
Docker can help businesses to boost savings dramatically by significantly reducing infrastructure resources as fewer resources are required to execute an application. Docker containers also ensure uniformity over multiple developments and release cycles that standardize the production environment.
