What are the main advantages of server virtualization?
Server virtualization has many benefits, but saving money, consolidating servers, and maximizing utilization are mentioned most often. Since everyone who plans to virtualize has these three benefits in mind, let's take a look now.
To save money
No matter which CTO you visit, just tell him how much money you can save by virtualizing, then he'll be a good listener. The key is how you express that advantage.
Here's a good example: you just bought five Windows2003 licenses for your five new servers and plan to invest them in the company's infrastructure, which will probably cost you between $10,000 and $15,000 in license fees.
If I told you That I could get you the same infrastructure for $2,000 to $5,000, would you believe me? You might be anxious to know how? It's simply that to buy a WindowsServer2003R2 license and you get up to four instances of virtualization for free, so you can download any virtualization software you like and install four virtualization operating systems for free.
Many hosting centers and enterprise server rooms are full of equipment. Especially in the hosted room, it seems that each vendor needs a separate server to run its own unique software. That's how the Dot-com era worked, but today we face rising energy costs in order to power these machines.
Indeed, in this halcyon age of technology, server rooms are the vampires of energy. How can companies cope with this increasing cost pressure? The first solution is virtualization.
The first and simplest step in intelligent integration is to list all the servers and software in detail and see how many servers are running a single application or even a legacy application. With virtualization, it is possible to consolidate applications from 20 servers into 5!
Maximizing server utilization and consolidating servers go hand in hand, and you can't do one without considering the other. When will the server be consolidated and when will the utilization issue be resolved?
Take a look around the server application scenario, and you'll find many servers with two or even four processors running only one small application, and their usage is not even registered.
In fact, these systems can hold three to five virtual instances if they reach their full potential. It is not uncommon these days to cluster all of your traditional applications and place them on a server with several virtual instances.
Indeed, by leveraging existing server resources through virtualization, you can not only cut costs but also effectively consolidate the servers in your application scenarios. So the new question is, with such a large number of virtual machines, how do you protect them? - Data protection tools are the best choice.Vinchin Backup & Recovery, the next-generation VM backup solution self-developed by Vinchin, supports the world’s most mainstream virtual environments including VMware, XenServer/XCP-ng, Hyper-V, RHV/oVirt, OpenStack, Sangfor HCI, Oracle Linux Virtualization Manager, and Huawei FusionCompute(Xen Based). It prevents the loss of critical business data due to human misoperation, viruses, attacks, hardware failures, natural disasters, wars, etc.
