Containers and Virtualization are ways to deploy multiple, isolated services on a single platform.


Virtualization refers to run multiple operating systems on a single machine at the same time.

A software layer called ‘hypervisor’ makes virtualization possible.


Dependencies, Libraries, and Configurations are contained within Virtual Machine. It is an operating system that shares the resources of one server. They have their own infrastructure and are isolated from each other.

VM  runs software on different OS without additional hardware


Containerization packages up code and dependencies for the application to run quickly from one environment to another.

It encapsulates an application in a container with its own OS and creates multiple workloads on a single OS instance.

It can be placed on any host machine without special configurations.

Machine Virtualization vs Containers

Quick Difference:



Hardware-level virtualization Operating system virtualization
Heavyweight Lightweight
Limited Performance Native Performance
Fully isolated Process-level isolation
More time to boot Few seconds to boot
Consumes high storage Takes lower storage as OS is shared
Sharing libraries is not possible Sub-directories can be shared
Same kernel, but different distribution Multiple independent operating systems
Supports all OS Supports Linux

Both differ in several ways but choosing one depends on the requirements.
