Which is better VM or container?
VMs are capable of running far more operations than a single container, which is why they are the traditional way monolothic workloads have been (and are still today) packaged. But that expanded functionality makes VMs far less portable because of their dependence on the OS, application, and libraries.
What are advantages of containers versus virtual machines?
Their containers perform faster than VMs, can be spun up and down a lot faster, and have better access to system resources. The main benefit of the container is their small size and the ability to run hundreds or even thousands on a server vs. a few dozen virtual machines.
Can you run a VM in a container?
The answer is a resounding “yes.” At the most basic level VMs are a great place for Docker hosts to run. Whether it’s a vSphere VM or a Hyper-V VM or an AWS EC2 instance, all of them will serve equally well as a Docker host. Depending on what you need to do, a VM might be the best place to land those containers.
