For the purpose of multiple webs hosting customers the role of providing features of a dedicated server is done by Virtual Private Server (VPS), or also known as Virtual Dedicated Server (VDS). At first look it may possess a contradictory appeal; how one can have a dedicated server which is being served by multiple users? Isn’t it looking like a regular shared or virtual hosting environment? There is nothing to contradict in the statement that, with a Virtual Private Server the user has to share system resources for e.g. CPU and RAM with other users but the resources are owed and modified in such a manner that it is impossible to predict that the system possess someone besides the user on it, to a large extent ideally like a dedicated server. Thus resources are modified and arranged in such a way that each hosting client is allowed to exploit an allocated percent, means the resources assigned to a particular user will always be there all time ready to serve him/her.
Merits of Virtual Private Server (VPS) web hosting
Majority of users prefer complete command of their server environments and do not wish to share the server with several other users, who could easily exploit all the available resources and can cause problem to other users by creating unbalance. But at the same time several websites do not require a dedicated server. The Virtual Private Server (VPS) alternative is a very fabulous slot hosting solution for a fairly large lump of web hosting clients who prefer the stability of a dedicated server however on a smaller scale. With the resources setup in such a way that each person can only use what is in his/her own share, one’s site will be more steady because it will always have the same amount of access to the CPU, memory, as well as to the bandwidth. Virtual Private Servers are preferably more safe since even as the user share the memory and CPU time, he/she are allocated his/her own file system. For an instance, if a website on the server is hacked, the hackers will be able to admit to that particular file system only and can not harm the other existing websites. Besides all these advantages, A VPS is also affordable as compared to a dedicated server.
Demerits of Virtual Private Server (VPS) web hosting
As till now discussion was on the pros of a VPS and one might think that this is the finest thing .But there is another side of the coin as well as, not all providers setup or define Virtual Private Servers, also known as Virtual Dedicated Servers, the exact same way. One should ensure that provider guarantees the user that their setup is robust enough to knob the operations at a peak level. A commonly prevailing trick generally put into use by the providers in the field of reselling and shared space is ‘overselling’. It denotes selling more in terms of services than what is physically available, with the gamble that the end users wouldn’t exhaust up all the service that were advertised in front of them. In the dominion of VPS this can be a bit more severe, as at least the expectation is that one is working in a more vigorous environment and there are many clients running more intensive applications like message boards or custom web applications. A shortage of resources could result in causing problems for each one hosted on such a server, therefore evading the benefits of a VPS. In a mutual or dedicated environment the user might be able to access more quantity of resources during peak or spike periods but since the VPS environment restricts the user to use his/her own piece of server resources, it can come in front as a drawback.
With dynamic and changing technology web hosting is not sufficient, in the same manner there are some problems with VPS services also. The user has to tackle with the problems of CPU cycles and RAM distant for storing of space and bandwidth. So the user will see advertisements for hosting that might include MHz and MB RAM to go with the usual hosting related features. It is something difficult to calculate out how much CPU time or RAM the user might require, so one must look for a hosting provider that will provide him/her with some benchmarks and the ability to upgrade or downgrade the VPS service as and when required.
– Permits complete control of user’s virtual server and its resources
– Permits the user to run web applications without unfavorably affecting other clients
– Flexible – cheaper than dedicated hosting, more expensive than shared
So Go ahead and best of luck!!!
