The open-source Docker virtualization technology is one of the most exciting innovations to enter the enterprise IT space in years. Docker is a container virtualization technology that offers the promise of a more efficient, lightweight approach to application deployment than most organizations are currently implementing.

 

 

How Is It Different from Virtual Machines?

Applications running in virtual machines, apart from the hypervisor, require a full instance of the operating system and any supporting libraries. Containers, on the other hand, share the operating system with the host.

Hypervisor is comparable to the container engine (represented as Docker on the image) in a sense that it manages the lifecycle of the containers.

The important difference is that the processes running inside the containers are just like the native processes on the host, and do not introduce any overheads associated with hypervisor execution. Additionally, applications can reuse the libraries and share the data between containers.
