For any webmaster shared web hosting is always a good solution in terms of expenses but when it comes to your control over server dedicated server is always preferred. This may be a good solution but it is far too expensive so webmasters must consider other solution like co-location hosting or virtual private servers.
Virtual private servers are normally a part of dedicated server sharing same hardware. In a dedicated server virtual partitions is made for which different type of virtualization software like OpenVZ are used. Webmasters may better decide which type of hosting they need but one thing is sure, VPS always give an edge over shared web hosting to webmasters. Here I have pointed out some major benefits of VPS over shared web hosting.
First thing which gives upper hand is the load of CPU. In case of huge traffic on your website, you many not suffer the performance of your personal website. Being an independent and completely anonymous to your neighbors, you do not have to share services or applications. This serves just like your servers being in your own home and you have access to the root directory. This is an important factor as webmasters sometimes need to install third party components for which server access is needed and you can easily do it without any limitations.
Another factor to consider in virtual private servers is the reliability. In case any fault occurs in shared web hosting server, every one suffers and surely webmasters become dependent on that host. On the other hand in a VPS hosting you own the server, do have root access and gets dedicated customer support so you succeed in overcoming such issues quickly and more comprehensively. If reliability have any significance to you, then paying little more will not bother you.
Security is also a worth considering factor for every webmaster. As compared to shared hosting, you do not have to share TCP/IP stacks, disk space or other resources. This makes VPS web hosting a better option for all businesses who care more about their security.
Inspite of what is good or wrong; most of the webmaster who prefer VPS over dedicated servers or shared hosting give the reason of cost. According to them, they need control over severs which shared web hosting companies do not provide. On the other hand, they could not afford to buy complete server so better they decide to have a part of that server.
In the end, virtual private servers are always a handy option for webmasters looking to get root directory access to their server. At the same time webmasters must check web hosting companies about their data centers so they ensure they are getting for what they are paying.
