Question

Each container has its own instance of an operating system.

Answer 1

Answer:

There is no need to install a separate instance of the operating system for each container, nor does the container perform a boot sequence, load libraries, or devote memory to the operating system files. Containers start in seconds, and you can create more containers on a host system than you can virtual machines.

Answer 2

Answer:

Containers start much faster than virtual machines and use fewer resources. This is because each container does not have its own instance and share an operating system. Instead, developers configure each container with a minimal set of software libraries to do the job.
