Virtualization services create digital copies of software or hardware, reducing physical space and memory usage. Application, desktop, hardware, server, and operating system virtualization all have different purposes and benefits. Virtualization reduces power consumption and allows for multiple processes to run simultaneously.
Virtualization services are digital copies of software or hardware, rather than physical models that take up extra space or memory. Application and desktop virtualization services are nearly identical, because each virtualizes software for a computer, but desktop virtualization is more intensive. Hardware virtualization breaks down a computer’s hardware into chunks, and each chunk is used for a different process. Server virtualization is similar, but involves installing multiple digital servers on top of a physical server, which reduces heat and power consumption and allows the server to run multiple processes simultaneously. Operating system (OS) virtualization breaks down hardware into chunks for the specific purpose of installing another operating system on your computer.
Application and desktop virtualization services both run on a desktop or laptop computer (typically for business purposes, so desktops are more common) that virtualizes software. When a computer is running, the software is normally stored on the computer and the computer accesses this software locally to run a program. With virtualization, the software is stored on a server external to the computer that the computer can access, which means that the computer itself does not have any software. Desktop virtualization is a little more intensive because it eliminates the need for a central processing unit (CPU), with all processing done through the server.
With hardware virtualization services, computer hardware is broken down into chunks. This can happen to almost any piece of hardware, such as the CPU, hard drive, or random access memory (RAM). When a section of hardware is split, that section can only be used for a certain purpose; for example, if the block is created for encryption purposes, the block will be used solely for encryption.
Server virtualization services are similar to hardware virtualization in that the hardware is subdivided; the difference is that this is exclusively for a server, while hardware virtualization is typically for a desktop or laptop. Creating a virtual server means taking several server programs and placing them on a server. While this reduces the overall power of each virtual server, since it relies on the hardware of a physical server, adding additional RAM can alleviate this problem. Virtualization reduces heat and power consumption, making server operation more economical.
Operating system virtualization services allow more than one operating system to run on a computer. The hard drive is divided into sections and each section has a separate operating system. Some computers are capable of running each operating system simultaneously, but most computers lack sufficient power and each operating system is used separately.
