Identify the difference between Docker containers and OpenVz containers

[ashay-maheshwari]

We are very comfortable with OpenVz and are exploring Docker. We must have clear idea of advantages of using Docker over OpenVz. Identify the differences between Docker and OpenVz containers. Factors can be performance, resource utilization, ease of use etc.

According to the ease of use :-
Docker is far simpler than OpenVZ.
Docker also introduces DockerFile, lightweight "configuration as code", that makes it easy to share containers.
Last but not least, docker index offers a simple way to distribute ready-to-deploy container images.

According to performance :-
OpenVZ :- OpenVZ sees a container as a VPS. For OpenVZ you can expect that when you create containers, its sort of like making Virtual Servers. OpenVZ has interfaces focussed on setting up VPS containers that you decorate yourself manually.

Docker :- Docker sees a container as an application/service. You can expect that when you create containers, the container is a single application, that just does ONE thing. Hence, it might need some other containers to help it. (For example a container that provides a database) Docker made it very easy to define whats inside a container without having to actually start one up, and constantly create new exactly equals instances of this container.
