Virtualization In Cloud Computing - Benefits and Types of Virtualization
Just imagine you have one storage and you partitioned the storage with some resources allocated to each segment of the separation to achieve different goals that’s a typical example of what virtualization is all about. In this article, we’ll dive into virtualization in cloud computing, benefits, and types of virtualization.
What is Virtualization
Before we dive into virtualization in cloud computing, let’s first understand what is the meaning of virtualization and why virtualization.
Virtualization simply means the creation of a virtual (rather than actual) version of a particular resource or specification of a system. This includes virtual computer hardware platforms, storage devices, and computer network resources. Anything from a server to an operating system. It allows you to turn one server into a host for a group of servers that all share the same resources.
Why Virtualization?
Virtualization can increase agility, flexibility, and scalability while creating significant cost savings. Greater workload mobility, increased performance and availability of resources, automated operations they’re all benefits of virtualization that make IT simpler to manage and less costly to own and operate. Virtualization offers many benefits such as isolation, partitioning, encapsulation, more environment execution, resource or device independence.
Virtualization In Cloud Computing
In cloud computing, virtualization plays a major role in allowing sharing of platforms, infrastructure, software resources in the cloud environment with many users. With cloud virtualization, customers can use only the parts of the service or resources they need, without needing the accompanying physical infrastructure themselves. For example, cloud virtualization technology for storage infrastructure allows users to access huge amounts of storage as they need it, and scale this need up and down as necessary, without needing any of their own storage.
Virtualization in cloud computing allows a provider to virtualize servers, storage, or other physical hardware or data centre resources, which can then, in turn, allow them to provide numerous services such as infrastructure, software, and platforms.
The difference between virtualization and cloud computing is virtualization allows you to create multiple simulated environments or dedicated resources from a single, physical hardware system and share them with many customers.
Cloud offers the application and services that the virtualization environment needs to run, this environment can either be public or private. which helps customers to maximize the resources allocated and reduces the physical system that they need to interact with.
Types Of Virtualization In Cloud Computing
There are various types of virtualization in cloud computing and not limited to the types listed below.
Data Virtualization
Data virtualization provides a virtual layer on top of the data storage system to allow easy access to data storage from a central place without getting to replicate data across different storage systems, consolidates data from different sources to a single source. There are some services that provide data virtualization such as Denodo on the Google cloud platform and Promethium.
Server Virtualization
This is a kind of virtualization in which the physical server is divided into a different virtual server with defined configuration for each virtual server so, each server can run its own operating system in an isolation manner. It causes an increase in performance and reduces the cost-effectiveness of maintaining each virtual server deployment.
Network Virtualization
This is a kind of virtualization in which the physical network is combined into virtual networks. Each virtual network is managed independently and co-exists on the top of the physical network. Network virtualization presents logical networking devices and services logical ports, switches, routers, firewalls, load balancers, VPNs, and more to connected workloads.
Application Virtualization
Software virtualization in cloud computing abstracts the application layer, separating it from the operating system. This way the application can run in an encapsulated form without being dependant upon the operating system underneath. In addition to providing a level of isolation, an application created for one OS can run on a completely different operating system.
Benefits of Virtualization
- Server consolidation and hardware utilization.
- Reduces the need for power, space, and cooling in the data centre.
- Reduces the cost of resources.
- Increases and enhance the development and testing environment.
- Eliminate the risk of system failure.
Conclusion
Virtualization is a technology that over the years has proved to be a very valuable concept in IT and also cloud computing. The concept of virtualization isn’t just about infrastructure. It’s about what your infrastructure can (or can’t) do to support the technologies that depend on it.
