Virtual Private Servers And Dedicated Servers Explained:
In this article: VPS also referred to as VDS or Virtual Dedicated Server, forms a part of a partitioned server. Each of these partitions is equipped with a separate operating system along with a guaranteed share of CPU, RAM and disk space. Although the server consists of numerous partitions, each partition operates like a dedicated server, but this hosting service can be availed at a much lower cost.
Let's try to discuss the problems faced in shared hosting. Shared hosting can be compared to living in an apartment and getting affected by the problems of neighbors. For example, one might be disturbed by a loud noise coming from the neighbor's house on the other side of the wall and when he leaves the main door open, all other neighbors' security are put at stake. The same operating system and resources are shared by all the websites on a shared server.
If a problem occurs in a neighbor's website, then it can result in a slowdown of the server performance or even a temporary shutdown till the problem gets solved. Again a shared server might contain too many sites which might cause a slowdown. The security of a website is dependent upon the decisions of the web host and the activities of its neighbors. As resources are shared, so a shared hosting entails cheaper costs than a VPS.
Majority of the websites are on shared servers. But VPS hosting would mean living in one's own private yard within a township. Here, no website has to share the troubles of its neighbors. The common area of sharing is the parking lot and the entrance. All the traffic has to pass through a common network port. One needs to pay more for a VPS, but he is free to do whatever he likes within the space allotted to him without facing the effects of his neighbors' problems.
VPS, though a bit more pricey that shared servers, would allow the webmaster to have greater control to install programs and configure them as per his needs with the option to reboot, backup and restore his VPS himself. One has the option to host multiple websites and add the domains himself. Only a webmaster can grant permission to others to access his accounts, files and databases. A particular website on a VPS remains unaffected by problems in other websites on the same server.
A webmaster can choose to offer hosting space to clients' sites with the option of offering private label reseller accounts. But one has to take care of his VPS maintenance, security and updates. If problems arise, then one has to find out the cause and the solutions himself. This would demand more time from the website owner. Those who are expanding their websites, need more resources to support the expansion and are concerned about control and security would definitely like to switch to VPS from a shared server.
