Docker vs. Virtual Machines:

Virtual Machine is an application environment that imitates dedicated hardware by providing an emulation of the computer system. Docker and Both have their set of benefits and uses, but when it comes to running applications in multiple environments, both can be utilized. So which one wins? Let's get into a quick Docker vs. VM comparison.

OS Support: VM requires a lot of memory when installed in an OS, whereas Docker containers occupy less space.

Performance: Running several VMs can affect the performance, whereas, Docker containers are stored in a single Docker engine; thus, they provide better performance.

Boot-up time: VMs have a longer booting time compared to Docker.
Efficiency: VMs have lower efficiency than Docker.
