Bare metal vs. VM vs. Container

Running application in bare metal is inefficient hardware resource utilization.

VM's Depends on virtualization platform

Need separate VM for each application deployment.

Not very efficiently utilize resources as each VM contains their operating system.

VM is not very convenient for high scale deployment.

Running multiple applications in a single VM is problematic.

VM image size is larger than container.

VM performance is almost 30% lower than container application as containers run on real CPU rather than virtualized CPU in case of VM.

Efficient use of disk space in container due to shared file system.

Container image can run on any platform that support standard container format with supported kernel version.
