So far, there is no definitive solution to this question, although based on their setups and limits, containers may be able to outperform Virtual Machines. The only point of view that suggests which one should be picked is application design. Containers are the ideal solution for applications that require expansion and high availability; otherwise, Virtual Machines can be used, however, Docker containers have certainly challenged the virtualization business. Leaving the dispute aside, it's easy to assert that containers in Virtual Machines are two times as reliable as containers alone.
The fundamental difference among these two systems would be that VMs operate on the exact hardware as virtual environments, whilst Docker operates on virtualizations of the very same operating system.
Because Docker containers use the same host kernel, apps only arrive with whatever they require to run—neither more nor less. Due to this reason, Docker applications are much simpler to launch, lightweight and faster to boot up compared to Virtual Machines.
Docker containers may operate both Windows and Linux programs and executables. The Docker platform is available for both Linux (x86-64, ARM, and a variety of additional CPU architectures) and Windows (x86-64)
You can run several containers on a single server, and the number of CPUs isn't a restriction. Your operation begins and maintains precisely one container with exposure to a maximum of 16 CPUs
