Containers and VMs each have their own use cases, many deployments of containers use VMs as the host operating system rather than running directly on the hardware, which provides one more additional layer of high availability in the form of Virtual Machine.

Below workloads can run on containers: Below workloads can run on the virtual machine: At the end of the day, every organization’s business needs and infrastructure are different and requires its own unique strategy.
