Docker is an open-source environment of product containers. These containers help applications to work while they are being shifted from one platform to another. This is a new era technology, which enables enterprises to ship, build, and run any product from any geolocation. It is true that several problems are associated with hosting environments and this Docker technology tries to fix those issues by the creation of a standardized way to distribute and scale the apps. In the current scenario, Docker has become popular among different cloud architecture machines. It permits applications to be bundled and copied where all apps are dependent on each other. Cloud users find this concept useful when it comes to working with a scalable infrastructure. When Docker gets integrated with cloud, it is named as Docker Cloud.

Docker differs from virtual machines by eliminating worries about which operating system is used. Docker enables the virtualization of the operating system itself with the application and every connected component.
