Top Benefits of Server Virtualization

Server virtualization creates virtual instances on the physical server thereby helping with cost saving, increased uptime, improved disaster recovery, and in a few more ways.


Top Benefits of Server Virtualization

If you want to enhance your network’s current performance along with its capacity and also want to know what are the requirements in the near future, then you need a technology refresh!

Server machines are powerful computers that host files and various applications centrally. They often have multiple CPUs which give servers the capability to handle multiple tasks simultaneously.

Network administrators assign a dedicated processing unit to each application. Although this approach makes it easier to track any issues that arise within the applications without disturbing others, it doesn’t leverage the immense processing power of the modern server computers. With this approach, we would require multiple servers as our network scales up. Server virtualization solves these problems by using specifically designed software that converts one server to separate virtual machines.

Server virtualization is the method of using software by creating various virtual instances on the physical server. It combines various operating systems on a single server. It reduces app downtime without exceeding the budget and increases technical capabilities.

Types of Server virtualization

Full Virtualization

In this model, full virtualization uses hypervisor which completely isolates guest machines and directly communicates to a physical server. The limitation of full virtualization is that it has its own processing needs, which can slow down the applications.

Paravirtualization

Paravirtualization model involves the whole network working together as one unit and eliminates the need for virtual machines to trap the instructions and make it more time-efficient. The operating system recognizes the existence of hypervisor, and then it directly communicates by comments known as hypercalls.

Operating System virtualization

OS virtualization model does not use hypervisor like Full and Para Virtualization as it allows the existence of multiple user-space instances.

Advantages of Server Virtualization

Cost Saving

Having less physical server means less maintenance and management. If a company switches from a physical server to virtual machines which reduce the physical server of the organization, that helps in saving the cost of power and cooling. Lesser physical server requires less hardware.

Increases uptime

Server virtualization offers advanced features which are not available in the physical server; the features helps to increase uptime. Server virtualization takes lesser time to implement new technology/application, recovery of data, and distribution of workloads.

Improves Efficiency

If the business uses server virtualization, the various virtual servers will be acting in place of one physical server. By this efficiency will only go up, and all virtual server will produce the same output as one physical server in a more effective manner.

Improves Disaster Recovery

One of the greatest benefits of server virtualization is the recovery feature. As the data is not tied with one physical server, it has various servers, so if data crashes in one entity, then there is no fear of data loss.

Image-based backups

Server virtualization comes with the benefit of backup and restores the entire virtual server; a business can quickly backup entire VMs and restore them. Additionally, image-based backups make the disaster recovery much easier and time-saving.

Allows to move to the cloud

By virtualizing servers and abstracting away the hardware, a business can prepare to move into the cloud.

The first step is to move to a private cloud from a public cloud. But as the public cloud matures and technology becomes more advanced, then the business becomes more comfortable to move data out of the data center into a cloud hosting facility

Disadvantages of Server Virtualization

Security Risk

Data security is crucial for the success of the business and one of the most significant factor. Server virtualization comes with a security risk as businesses have to spend extra for data security to ensure its data safety.

Not all applications can be virtualized

One of the major drawbacks is that all applicants are not virtualization-friendly; the reason behind it is that not all hardware or software vendors support it. Even though most of the applications do support the virtualization.

Upfront costs

Depending on your existing hardware and network, the additional investment might be required to install hardware for the implementation of server virtualization. More often than not, businesses have sufficient infrastructure to accommodate virtualization. You can work with a managed IT service provider to figure out the best possible option for your business; whether you should opt for purchase plans or should you go for monthly leasing.

Conclusion

As we can see, server virtualization has more advantages than disadvantages, and it is growing with the advances in technology solving and facilitating many operations. If a company wants full control over the server, virtualization is the best choice.
