Why do we use Docker Machine?

There are two main uses of the docker Machine:

1. Old Desktop: If we have an old desktop and we want to run Docker then we use Docker Machine to run Docker. It is likeinstalling a virtualmachine on an old hardwaresystemto runDockerengine.
2. Remote Hosts: Docker Machine is also used to provision Docker hosts on remote systems. By using Docker Machine you can install Docker Engine on remote hosts and configure clients on them.
