Difference Between Containerization and Virtualization

Difference Between Containerization and Virtualization
In this blogs we’ll discuss Difference Between Containerization and Virtualization in deep. First detailed explanation of Containers and then virtual machine.

What is Containerization?Difference Between Containerization and Virtualization

  • Containerization is the process of taking virtualization to the operating system level
  • It brings abstraction to the operating system and also is a type of Virtualization
  • Containerization is more effective because there is no guest OS and uses a host’s operating system, share relevant resources and libraries as and when needed, unlike virtual machines.
  • Application specific libraries and binaries of containers run on the host kernel, which makes execution and processing speedy.
  • They are more lightweight and faster than Virtual Machines.

What is Docker?

In the process learning Difference Between Containerization and Virtualization. We should understand “Docker”. Docker is a containerization platform that packages your application and all its dependencies altogether in the form of Containers to secure that your application works seamlessly in any environment.

Every application will run on a separate container and will have its own set of dependencies and libraries.It also guarantees that there is process level isolation, which means all application is independent of others, providing developers guarantee that they can create applications that will not conflict with one another.

What is a Virtual Machine(Virtualization)?

Virtualization is the process of importing a Guest operating system on top of a Host operating system. This technique was a discovery at the beginning because it enabled developers to run many operating systems in various virtual machines all running on the same host. This process removed the need for extra hardware resource.

The advantages of Virtualization or Virtual Machines are:

  • Many operating systems can run on the corresponding machine
  • Recovery and maintenance were easy in case of failure states
  • The total price of ownership was also small due to the decreased need for infrastructure

Containers and virtual machines also called as hyper visors are two systems used to separate two interfaces on one device. A typical case is corporate and personal data on an employee’s phone whose company enables an enterprise mobility strategy.

VMs build and manage many guests operating systems on a host device. Virtualization with hypervisors can be one of two types:

  1. Bare-metal virtualization that runs directly on the hardware
  2. Hosted virtualization that functions on top of hosted OS

Containers, on the other hand, run on the same OS and provide a hidden platform that doesn’t use a host device’s physical resources. This process is a more active approach regarding memory and storage usage, plus a container can be quickly deleted or removed from a device if it’s hacked.

Let’s assume that you understand the essential concepts of Virtualization and other related principles; we’re going to state that there are two significant differences between a Container and a Virtual Machine (VM):

A Container’s system needs an underlying operating system that implements the necessary services to all of the containerized applications using virtual-memory support for isolation. VMs, on the other hand, have their operating system using hardware VM support by the Hypervisor.

A Container provides an abstract OS, while A VM offers an abstract machine that uses device drivers targeting the abstract machine.

Both differences are somehow related to each other, but that is the only point that distinguishes one from the other.Container methods usually target environments where hundreds of containers are in action, and thus resource provision is one factor that means a lot while comparing these two.

We hope this helps. All the best and happy learning!
