Virtualisation in cloud computing is a terminology that refers to creating a virtual version of computer resources such as operating systems, storage, etc. It not only provides a virtual environment for accessing applications but also for memory and networking.
Read on to understand how virtualisation works and its types and benefits.
How does virtualisation work?
Virtualisation divides computer hardware elements into multiple virtual computers or virtual machines (VMs). It is done using software to fabricate an abstract layer over various elements of a computer system like processors, storage, etc., allowing the VMs to function as their own operating systems. This means that each VM will behave like an individual computer unit, even though it only utilises part of the total hardware.
In short, virtualisation is cloud providers’ main cost-cutting, hardware-reducing, and energy-saving technique.
Types of virtualisations in cloud computing
Cloud virtualisation is of 5 broad types. They help in the virtualisation of various elements of IT infrastructure. These are:
- Desktop Virtualisation: This virtualisation allows you to run multiple desktop software. Each software runs in a different virtual machine (VM) on the same computer.
- Application Virtualisation: Application virtualisation can run application software without being directly installed on the user’s operating system.
- Network Virtualisation: Network virtualisation creates a provision for VPNs, routers, firewalls and load balancers.
- Data Virtualisation: An affordable form of data integration, it allows any application to access data irrespective of the type and where it is stored.
- Storage Virtualisation: This virtualisation can help bring all individual storage blocks under one shared pool. It can then be assigned to any VM on the network as per the requirement.
Benefits of virtualisation
Let us now understand the benefits of virtualisation in cloud computing:
- Enables a more efficient allocation of resources
- Allows running multiple operating systems
- Enhance the productivity of development
- Lowers the cost of IT infrastructure
- It can be accessed remotely
- Rapid scalability
In today’s world, virtualisation has become an integral part of a company’s IT architecture. It’s the basis on which the Everything-as-a-Service (EaaS) computing model works. If you want to become a virtualisation engineer, familiarise yourself with cloud technologies and seek out upskilling courses to help you stay job ready!
Frequently Asked Questions
Q1) What is a hypervisor in cloud computing?
Ans) Hypervisor in cloud computing, or Cloud Hypervisor, is a software that enables sharing of cloud provider’s memory resources with different VMs (Virtual Machines).
Q2) How do I become a virtualisation engineer?
Ans) To become a cloud virtualisation engineer, along with a cloud computing certification, you will need a degree in any of the following subjects;
- Computer Science
- Information Technology
- Wireless Technologies
Q3) Is virtualisation a promising career?
Ans) Yes, virtualisation is an excellent career to pursue. Acquiring virtualisation knowledge can enhance your career, as these skills are twice as valuable in the job market. Furthermore, the virtualisation sector is expected to grow at a compound annual growth of 25% in the next four years. Therefore, this will open career opportunities.
