The term "cloud" is nearly omnipresent in our everyday life. The line that divides cloud computing from virtualization is often unclear to non-experts. Many confuse them by overlapping the two concepts. Before choosing and implementing cloud services, it is essential to be well informed as the right choice can affect the project outcomes. They both support the IT infrastructure but with different approaches, requirements and benefits. Let's dig deeper to understand how cloud computing and virtualization work.
Virtualization: from physical to virtual servers
Server virtualization means partitioning physical servers into multiple virtual servers. Each virtual server becomes autonomous and runs its own operating systems and applications. This way, the pooling of physical resources combined with management tools provide higher and more efficient utilization of physical resources, minimizing the need for physical devices.
Based on software, this procedure divides the resources between multiple virtualized and isolated servers called Virtual Machine (VM). You can generate a virtual machine that enables you to run several operating systems and applications on the same server. For example, you can create a Windows and a Linux server for various purposes on the same physical server.
The computing service layer and the physical equipment are separated. Thus, deploying different machines on a single hardware, virtualizing servers, desktops, storage, or other systems is possible. Meeting load requirements is effortless and can be handled more dynamically, reducing costs by better utilizing physical servers.
