Difference between virtualization and containerization

VMware Computers Hardware Operating System

Virtualization is the technology which can simulate your physical hardware (such as CPU cores, memory, disk) and represent it as seperate machine. It has its own Guest OS, Kernel, process, drivers and etc. Therefore, it is hardware level virtualization. Most common technology is VMware and VirtualBox

Containerization is os-level virtualization. It doesn't simulate the entire physical machine. It just simulate the OS of your machine. Therefore multiple applications can share the same OS kernel. Container play similar roles to virtual machine but without hardware virtualization. Most common container technology is Docker

Sr. No.	Key	Virtualization	Containerization
1	Basic	Virtualization is the technology which can simulate your physical hardware (such as CPU cores, memory, disk) and represent it as seperate machine	Containerization is os-level virtualization. It doesn't simulate the entire physical machine
2	Detaching Layer	It used Hypervisor to detach the physical machine	It used docker engine in case Docker
3	Isolation Level	It has hardware level isolation so fit is fully secured	It has process level isolation
4.	LightWeight	It is heavyweight	It is very lightweight
5.	Portable	It is not portable	It is very portable. We can build, ship and run anywhere
