Why it’s actually not a VM

Containers don’t come with the weight of a full OS image and a hypervisor.

Containers include only OS processes and dependencies necessary to execute the code inside them.

Containers occupy less space(MBs not GBs) which means you can run multiple copies of the same application on the same hardware.

Containers are faster and easier to deploy, provision and restart. This make them ideal for CI/CD pipelines and a better fit for Agile development teams.
