What is the Difference between Virtualization and Containerization?

Virtualization is the process of creating virtual machines (VMs) to emulate physical machines, each with their own operating system. With VMs, multiple virtual computers can reside on one physical computer.

What makes VMs function is a hypervisor. Implemented either through software or a firmware layer, hypervisors allow multiple VMs to coexist and share the resources of a single physical computer, such as processing power, storage and memory.

Containerization, on the other hand, is the process of creating containers. Containers, in essence, encapsulate an application: its executables as well as its libraries and frameworks.

Containers share the kernel of a host operating system with other containers. So, you don't have to dedicate one computer to one application. Multiple containers can run on the same machine at the same time, using the same operating system.

In general, you use virtual machines for long-term tasks, such as running a website, while you use containers for tasks that have a far shorter lifecycle.
