Virtualization is the abstraction of IT resources that masks the physical nature and boundaries of those resources from users,” according to Gartner. Virtualization software allows to you run two or more operating systems using only one PC. So it is two or more computers in one. One is physical, and the others are virtual. Virtualization can refer to any instance of one IT resource hosting multiple other IT resources, including applications, clients, servers, storage capacities or networks. Virtualization software is also called a hypervisor, is what allows one computer or server to host multiple operating systems.
What does virtualization software do?
Your resources are finite. Virtualization enables to you get more value out of them. Run the more software and complete more processes with the same amount of hardware.
Back it on up
Virtualization makes backup your entire operating system or server installation as easy as backing up a group of files. Let us say a hacker takes down your mail server. If you’ve been running on a virtual machine, you can just restore the old version.
Run a different OS
First step is doing that should be taking a snapshot of your computer. Then you have to worry about the computer will let you shrink it enough. Having a desktop version of Linux for special use obviates the need to install PuTTY on Windows. Linux has to communicate via secure shell (SSH) built-in.
Run ancient apps
Virtualization includes running apps on old operating systems. Let’s say you’ve got a program that only runs on Windows 8, but you upgraded to Windows 10. Just use the virtualization to run Windows 8 on the same computer.
Look at dirty files
Virtualization software is also allows you to create a snapshot of your computer. This means is save all the settings and hard drive contents away in another part of the computer. And, more importantly, it means you can easily reverse those changes by reverting back to the earlier state. So let us say you get a file that you really need to read or watch or listen to, but it’s infected with a virus. If you take a picture of your machine before opening the file, you can view/watch/listen to the file and then revert back to your saved version.
Protect your computer from browser stank
Hackers have successfully broken all of most popular browsers Chrome, Internet Explorer, Firefox and Safari. Keep your computer safe from browser hack by running your browser of choice in a sandbox. The browser or plugin gets hacked, your computer can stay safe with virtualization. The corrupted file as a snapshot restores everything to normal even if a hack occurs.
Try an application on for size
If you create a copy an existing installation of an operating system and its data, you can run a virtualized instance and make sure configuration changes or updates won’t mess anything up without putting your actual installation and data risk.
“Virtualization is also improves the disaster recovery, load balancing, and software testing; reduce hardware costs; save energy; and reduce the physical size of your company’s data center,” writes David Coursey for PCWorld. The ultimate point of virtualization software is flexibility.
Virtualization Software Options
The 800-lb gorilla is VMwarewrites Kenneth Hess for ServerWatch. “VMware dominates the server virtualization market. Its domination doesn’t stop with commercial product, VMware vSphere. VMware is also dominates the desktop-level virtualization market and even the free server virtualization market with its VMware Server product. The company’s Azure cloud services as well as interested in managing both on-premises Hyper-V services and Azure services.” Features including live migration and failover clustering make it an attractive option. ManageEngine Applications Manager is more than a hypervisor. It also offers application and data center monitoring. Use it to make sure your web applications, web servers, application servers, databases and systems are up and up-to-date. “The cost difference for hypervisors is primarily based on licensing advanced features so to determine your licensing costs, you need to determine which advanced features are required in your environment.”
