Server virtualization has been around for over a decade. However, it has recently gained a lot of traction among tech behemoths and government agencies. These servers utilize less than 10% of the OS capacity and operate on Windows, Unix, and Linux operating systems. If a government agency wants to shift to cloud computing, virtualizing its server infrastructure is a must. This article is mainly about the benefits one can get by adopting server virtualization for their organization. But let's understand the concept first.
The practice of separating a physical server into numerous unique and separated virtual servers using a software application is known as server virtualization. Each virtual server has its own operating system. There are three types of server virtualization: full virtualization, para-virtualization, and OS-level virtualization. Server virtualization is a low-cost method of delivering web hosting services while making the most of existing IT infrastructure resources. Servers only utilize a tiny portion of their computing power without server virtualization. Because the burden is allocated to only a subset of the network's servers, servers become idle.
This is the generation of cloud computing, and everyone who uses the internet is joining "the cloud". You're preparing for a cloud migration as well by virtualizing your servers and abstracting away the underlying hardware. Moving from a simple virtualized data center to a private cloud might be the first step. You will have a good start in getting there as the public cloud evolves and the technology surrounding it advances, and you get more comfortable with the idea of transferring the data to a cloud hosting facility from the data center.
Your organization will save costs on electricity and cooling by converting physical servers to virtual servers and lowering the number of physical servers. Additionally, you'll be able to reduce the data center footprint, which includes expenditures for diesel generators, UPS, network switches, rack space, and floor space.
Most server virtualization solutions now provide a variety of sophisticated capabilities that aren't available on physical servers, allowing for greater business continuity and uptime. While vendor feature names may differ, most vendors offer live migration, storage migration, fault tolerance, high availability, and distributed resource scheduling. These innovations keep virtual computers running smoothly or allow them to recover from unanticipated disruptions swiftly. One of the most important single benefits of virtualization with far-reaching applications is the ability to move a virtual machine from one server to another effortlessly and quickly.
The ability to migrate a running virtual machine from one host to another with no downtime is undoubtedly one of the most influential capabilities of server virtualization. VMware's vMotion can help you with this, and it also allows you to use other VMware technologies like distributed resource scheduling (DRS) and distributed power management (DPM).
Imagine being able to give your business units near-instantaneous capacity when a request comes down the chain as a data center administrator. Server virtualization allows elasticity in capacity, allowing for rapid system provisioning and deployment. To get a server up and running quickly, you can clone a gold image, master template, or existing virtual machine.
While being bound to a single server vendor or even a single server type isn't necessarily a bad thing, it can be aggravating at times. However, because server virtualization abstracts away the actual hardware and replaces it with virtual hardware, data center administrators and owners have many more options when it comes to server equipment. When it comes time to renew or acquire new equipment, this may also be a useful negotiation tool with hardware sellers.
In your environment, you most likely have outdated legacy programs still functioning. These applications are most likely to fall into one or more of the following categories:
You may extend the life of an application and its environment by virtualizing and encapsulating it, as well as preserve uptime and finally get rid of that old Pentium computer in the data center's corner.
To isolate applications in the real environment, data centers often use a "one app/one server" paradigm. Physical server sprawl, greater costs, and idle servers emerged as a result of this. By aggregating many of these virtual machines over significantly fewer physical servers, server virtualization enables application isolation and eliminates application compatibility difficulties. This also reduces server waste by making better use of actual server resources and supplying virtual machines with the exact amount of memory, CPU, and storage that they require.
Physical servers are being converted to virtual machines and consolidated onto considerably fewer physical servers, resulting in decreased monthly data center power and cooling expenses.
This one is related to the preceding advantage. Server consolidation using virtualization will minimize the total footprint of your data center, in addition to reduced energy footprint. That means fewer servers, networking equipment, and racks are required, all of which implies fewer data center floor space is required.
Server virtualization has been a genuine "game-changer" for us since it had given us efficiency at a time when we really needed it. This article outlines the ten advantages of switching to new servers as it is very important to understand the real benefits of virtualization, whether you are new to it or not.
