What are the advantages of Docker?

As a new virtualization method, docker has many advantages compared with traditional virtualization methods.

First of all, the docker container can be started in a few seconds, which is much faster than the traditional virtual machine method. Secondly, docker has a high utilization rate of system resources, and a host can run thousands of docker containers at the same time.

In addition to running the application, the container basically does not consume additional system resources, which makes the performance of the application high and the system overhead as small as possible. Running 10 different applications in the traditional virtual machine mode requires 10 virtual machines, while docker only needs to start 10 isolated applications.
