Cloud computing is a popular term used now. Everyone is talking about it. Cloud and virtualization can be confusing as both have some common features. Cloud computing and virtualization are two different things.
What is virtualization?
Virtualization is a virtual simulation of a resource or device. It usually means dividing a single hardware into two or more segments. Each segment works as an independent environment. For example, server virtualization divides one server into different smaller virtual servers. Virtualization makes computing environment independent of physical infrastructure.
What is a cloud?
We get the origin of cloud computing from virtualization. You can consider cloud as a service; whereas, Virtualization is technology. Cloud computing is a situation where shared computing resources and software are delivered as a service through the Internet. Cloud computing allows broad network access, the ability to scale resources and more.
How do they differ?
You can have virtualization without a cloud, but the opposite cannot happen.
Virtualization makes one computer perform like many independent computers. On the other hand, cloud computing lets different companies access a single application.
Virtualization is employed locally. But cloud computing is accessed as a service.
As both these terms are quite new, many people don’t know the actual difference between them. Now you know that these two are different and can use them in your business where appropriate. Both have great benefits. You will be able to manage your resources better and enhance the efficiency of your business. You will also be able to save a lot of money in the long run.
Many companies are now embracing virtualization. It is an important step for companies now to stay competitive and manage the extensive information they have to handle every day. Here are the top reasons for companies to go virtual.
Virtual machines will give you a better return for money. Businesses will save money by implementing virtual servers. There will be lower power consumption and less expenditure on hardware. So, overall there will be significant cost saving.
As businesses grow, the IT system needs to be scalable to include more information. This is easily achievable with virtual machines without disrupting the present business. Virtual environment provides more flexibility.
Better disaster recovery option
With virtual servers, data recovery is easier. The absence of physical hardware makes the restoring process convenient. The cost of data recovery is also cheap. Backing up a virtualized infrastructure is done by making copies of VM files images. This is a lot easier than using disparate hardware servers to make the copies.
Migration to the Cloud Becomes Easier
It is convenient to migrate virtual environments to the cloud-based provider than managing these with physical hardware. Security and control can still be retained during the migration process. Business continuity can be achieved; that is, there will be no interruption of business operations during the period of migration.
So, virtualization is the trend, and this is what your business must also follow. If you haven’t shifted to virtualization yet, then you should do so now and start saving money.
If you haven’t tried virtualization yet, then you may be left behind. Most companies are going for virtualization for reaping all the benefits it has to offer. Virtualization means that you can run two or more operating systems on a single physical PC. There are lots of interesting things you can do with virtualization.
1. Run old apps
If you have an application that won’t run in Windows 7 or Vista but works with XP or the older versions of Windows, then you should get an old Windows CD and install it in your virtual machine. Then just install the app. When applications run in the virtual machine, it appears as if they are running on your host computer.
2. Read virus-infected data
If you have an important file that your antivirus program has detected as being infected by a virus, then you can still open the file using virtualization. There is a feature called ‘snapshot’ in virtualization software that lets you create a saved state of the virtual OS and the hard disk.
3. Test software, new configurations, or updates
You can use a virtual machine to test updates, software or new configurations of software before running them on your main operating system.
4. Run Linux on Windows (or vice-versa)
You can easily run Linux on top of Windows or vice-versa. So, instead of repartitioning your computer’s hard disk you can install any operating system inside a virtual machine. Mac and Linux users are using virtualization for many years to run Windows on top of their chosen OS.
5. Back up an operating system
Backing up OS in the virtual machine is just like backing up any other file. This is not possible in any other way and so encourages many people to move to virtualization.
Virtualization offers lots of benefits. Businesses can run more efficiently on a virtual machine. Many interesting tasks can also be done with it. It is the future of computing.
