Key features of server virtualization software

There are some basic features all server virtualization vendors must offer, such as hypervisors and VM management. Additionally, security and compliance have also become must-haves, and network management, storage, and scalability are features most companies today look carefully into. 

On the other hand, some new features, like tracking energy consumption, providing high computing power to drive AI and ML, and intense graphics and video are also in high demand. Let’s break down the top features.  

Hypervisors 

Hypervisors are at the core of all server virtualization software. They allow companies to create, deploy, run, and manage VMs on a single physical server. 

Resource management 

Resource management features give users insight, visibility, and the tools necessary to better allocate, assign, transfer, and manage resources to get the most out of their hardware and software. Resource management may be seamless and centralized or complex, depending on the vendor´s solution. Because these features are used to optimize your resources and improve performance, companies must make sure their team of experts fully understand how they work.

Storage 

Server virtualization software allows users to pool physical storage resources and present them to VMs as a single logical volume. This can help to improve performance and scalability.

Security, compliance, and backup and recovery

From updates, role-based access control (RBAC), and encryption to backups and automated compliance, server virtualization vendors will offer different security features to meet modern demands.

Innovation

Technology continually innovates at a high pace and top vendors respond by offering support for them. From AI and ML to 3D graphics, if your company works with innovative tech, it’s essential to know whether they will be supported. New technology will consume a lot of computing power and have strict hardware and software requirements. 

Sustainability monitoring

A more recent addition to some virtualization services, sustainability monitoring helps businesses keep track of their energy usage and find ways to limit consumption while preserving operational efficiency. Besides the environmental impact, this can save companies tremendous amounts of money over time, as ballooning data storage needs come with ever higher power consumption and cooling expenses.

How to choose the best server virtualization software for your business

There are several factors that companies need to consider before deciding on which server virtualization software is best for their business. 

Companies must first outline their business goals and answer the question of what they are trying to achieve and how server virtualization can help them achieve those targets. The goals must be outlined, whether it be reducing IT costs, consolidating systems, modernizing, or improving performance. 

What follows is an honest evaluation of the budget. While switching vendors is possible, migration can be complex. Therefore, companies must know how much they plan to spend today and in the future. Licenses are a significant differentiator in the market, with some solutions being affordable and others ranging up to thousands of dollars a month. Furthermore, if your company plans to scale, it’s essential to establish budget considerations. 

The next step is to evaluate each vendors’ features against your company’s goals. We have already discussed the top features from hypervisors to resources management, networks, and security. Companies can also read online reviews from trustworthy aggregate confirmed review sites. 

Frequently Asked Questions (FAQs)
