Both virtual and physical servers have their pros and cons, offering a range of benefits to businesses. But how do you know which is best suited to your needs?
Every company needs a secure and reliable server that means the needs and demands of daily business can be met. Being able to access adequate storage and process data and applications at high speeds ensure that work runs smoothly and you can access everything as and when you need to.
On top of this, a server needs to be cost-effective, offering an affordable solution that doesn't come at the expense of security and function. In many cases, a server must also comply with specific regulations, which must be taken into account when selecting the best possible option.
While previously, physical servers were largely thought to be the most secure, the advancement of cloud computing has meant that businesses are looking for alternative solutions. This means that companies need to weigh up which option works best for them, assessing the pros and cons of physical and virtual. Here are some of the advantages and disadvantages of both options.
One of the biggest benefits of physical servers - or dedicated servers - is that they provide complete access to dedicated server resources, meaning you won't experience slow processing at peak times. As Tech Wire News points out, this is ideal for businesses that deal with a large amount of traffic, as the dedicated hosting is entirely reliable and efficient.
There are also no outside interruptions, with the server belonging to the company. This allows you to assign resource to specific tasks in order to meet demand, ensuring everything runs much smoother. Not only is this ideal for keeping websites fast and up-to-date, even internal communications can be quicker.
However, physical servers can take up a lot of room, especially if you require a powerful one. They need to be housed either on-site, which can take up prime real estate, or at a data center. Not only does this mean that you need to maintain the area they are housed in, it is also the company's responsibility to perform any repairs or servicing, which can cause issues if something goes wrong.
When you factor in the costs of administration, management, processes and the actual server itself, physical servers come with a very high price tag. Running and maintaining physical servers adds to monthly company outgoings, especially if more servers are needed over time.
A virtual server differs from dedicated servers in that multiple servers can be added to one device. This can mean that you don't need to have the physical equipment on-site, as your virtual server can be located in a data center, allowing you to access it through cloud computing.
Ultimately, as TechGenix explains, multiple operating systems (OS) can be run at the same time, making efficient use of the physical equipment and meaning you don't need to run different ones for each OS. One of the biggest benefits of this is the lower cost, as the running of the virtual servers is a lot cheaper, which is ideal for both SMEs and larger firms.
However, the upfront cost can be a lot higher if you are purchasing servers that allow for virtualization rather than making use of a data center, which means the costs can take longer to recoup. When you also factor in the cost of IT department training on how to set up and run a virtual server, it can look like an expensive investment at the start.
One aspect of virtual servers that is incredibly useful to companies is the fact that many operations can be automated. This allows your IT department to make use of the automation available to create more regulated actions, saving workers’ time. It can also ensure that repairs are much easier, as any interruption in automated actions due to a fault will be flagged up.
Perhaps the biggest benefit of virtual servers is the fact that backup and recovery is much easier than with physical servers. If one server happens to fail, it is able to move to another machine. On top of this, the virtualization software that's used means that there is a better chance that recovery will be quick and easy, particularly compared to physical servers. This ensures that valuable data is better protected and that the company is able to get back online much quicker.
While the process of switching from a dedicated physical server to a virtual one can be time-consuming, with IT departments needing to be trained in the best ways of making use of the new environment, once it is fully set up, there are a lot of benefits to virtual servers.
