These days you can easily come across so many different web hosting plans. Each of them has their own plus points and negative points too. The least expensive and quite popular enough is shared hosting. Here, there are hundreds of web sites which are all sharing a single and large hard drive. However, this type of hosting is not suitable for all types of sites. There are certain websites which get high traffic. Usually, those websites which get high traffic are the ones who opt for a dedicated server. Virtual Private Servers is considered to be the poor mans dedicated server.
In a VPS hosting, the server is partitioned into multiple private spaces. Although you are still sharing a server with other clients, yet you get your own private ‘slice’ of this server. In such a situation, your website performance will not be affected by the other clients who share the same server. This is because each client has his own virtual private space in which they run. Hence, clients who opt for VPS servers, has access to the same type of services which is similarly compared to a dedicated hosting concept. Shared server accounts often depend upon the performance and good behavior of the neighboring accounts. Suppose, if one account violates their terms of service by sending emails, this type of action will load the server and in the bargain, it will create an adverse effect upon the performance of all the shared server accounts that are available on that particular server.
In the case of a VPS account, even if your VPS neighbor acts badly, it will not have any impact on other neighboring accounts too. They will tend to impact only their own account. This is because each account has the ability to appear like a separate server to the Internet. Also, the neighboring accounts cannot grab your memory at all. VPS is less expensive compared to a dedicated server. It also gives you more freedom and several options towards growing on-line business than shared hosting. Some people, who have a website with low-to moderate traffic bound website, are happy with the amount of control offered by a web hosting control panel like cPanel or Plesk. Such individuals will prefer shared hosting for simplicity and to use it in an easy manner. These types of people do not have linux system administration experience and they are not concerned in picking up any. There are others who have outgrown their shared hosting account or are not happy with the performance of the website. If such a situation arise, then it is high time that they now move to a VPS account.
A VPS can be set up with whatever software and can be configured in whatever manner the developer needs. A VPS can be used for small ecommerce sites with greater security and it has the ability to use more sophisticated software than that is available on a shared hosting plan. Through VPS, one can enjoy more uptime which is good for ecommerce merchants. Also, if one VPS crashes, it will crash without affecting any of the other virtual machines that run on that server. Due to this technique of compartmentalization, virtual servers will have no access to other virtual servers on the same physical machine.
This leads the VPS plans to become a bit more secure than traditional shared hosting plans.
