Benefits of Virtual Private Servers

Virtual private servers are shared servers that run inside of a virtual physical server. A lot of companies have started offering virtual private servers that include FreeVSD, Sphera, and Ensim. Sphera and Ensim do not host anything, but serve as a license to their virtual private server technology towards other hosting companies. The popularity increase of virtual private servers has a lot to do with the green movement and consumers seeking faster, more convenient ways to manage their business transactions online and offline. With reduced costs and user-friendly convenience, virtual private servers have become incorporated into the best businesses.

Every private server must have performance isolation, meaning that other private servers that use the same physical server won’t be affected by any kind of heavy traffic or CPU load. Limitations still occur on the process, memory and CPU. Every private server also has functional isolation, meaning that with other private servers, a virtual private server will not share a file system. Therefore, no processes are shared and the virtual private server is invisible to the other servers. Fault tolerance, which is another mandatory part of every private server, means that other virtual private servers won’t be affected by the errors on one private server. Every virtual private server receives IP addresses and network stack.


Root access is given towards individual private servers, thanks in most parts to a virtual private server. With this approach, applications can be run and your virtual private server can be managed completely the same way as they would when using a dedicated server. When using a virtual private server the bandwidth, uptime, disk space, and CPU are all guaranteed, in other words QOS/SLA is guaranteed. Enhanced security is another included feature, where processes are not shared in private virtual servers, TCP or IP stacks, or even disk space.

Using a virtual private server has many advantages. Control over their virtual or regular dedicated server is one of the advantages, allowing applications to be installed and run. Security is another factor, making sure that space is never shared together with other customers. Virtual private servers provide isolation which is another good advantage for users. This way, by other peoples mistakes, any risk of downtime is eliminated, including faulty scripts, hacks od other means of attack. Last but not least, virtual private servers provide optimum performance, ensuring additional resources for further expansion of their website.

All the above mentioned advantages answer the question why users are turning toward virtual private servers instead of dedicated servers. Primarily, before virtual private servers massively dominated the market, users relied on dedicated servers to provide the previous mentioned items. They had the same performance, security and control from dedicated servers. Using a virtual private server instead of a server that is dedicated provides the same benefits for users for a very small cost. This is where the advantage in using virtual private servers really stands out. Plenty of websites that use a dedicated server, are not wasting more than five percent of the dedicated machine.
