The process of designing, creating, and implementing a data center using virtualization and cloud computing technologies is known as data center virtualization.
It primarily allows for the virtualization of physical servers and storage, networking, and other infrastructure devices and equipment in a data center facility. Virtualization of data centers typically results in a virtualized, cloud, and collocated virtual/cloud data center.
Virtualization of a data center refers to a set of tools, technologies, and processes that enable a data center to function and provide services on top of a virtualization layer or technology. Datacenter virtualization allows an existing or standard data center facility to provide/host numerous virtualized data centers on the same physical infrastructure, all of which can be accessed by different applications and organizations simultaneously. This improves IT infrastructure/resource utilization and lowers data center capital and operating expenses.
Virtualization has undeniably grown in popularity in the IT industry, but why? Increased CPU utilization, increased space utilization, and the ability to standardize server builds are more obvious reasons. When it comes to CPU use, more servers on a single physical computer usually mean more work for the CPU.
Instead of receiving all Web traffic on one machine, all SMTP traffic on another, and all FTP traffic on still another, all of this traffic can be received on a single physical machine, increasing CPU utilization. However, achieving this successfully necessitates exercising caution while deploying numerous virtual machines on a single host computer, as this scenario can reduce performance.
Virtualization’s increased CPU consumption has an indirect impact on space utilization. With the situation mentioned above in mind, where several servers are housed on a single physical system, it stands to reason that virtualization will require fewer physical machines and, as a result, less space.
Virtualization is well-suited to the principles of cloning, ghosting, snapshots, and application software now available. This gives a system administrator the freedom to create images of any operating system on the network. A system administrator can develop custom images to establish a default build that can be duplicated across the network. When configuring extra servers, the time saved is priceless.
