Virtual Private Servers – How Do They Work?
Virtual private servers are an alternative for those who may be outgrowing a shared web hosting but not ready for a dedicated server. To understand how a virtual private server works it is important to also know what the shared and dedicated hosting do. In gaining a clear understanding of how each work, a web owner can determine which hosting type will best fit business needs of their web page. If the business is already well established and needs more of the resources to run the page then a dedicated server might be the best option. With a dedicated server, one server provides all necessary resources for one web page.
With a dedicated server, the web owner has more power and control of the page. The web owner must also be knowledgeable of technology because they will be doing most of their own page maintenance. Going with a dedicated server will set you back a little financially so it may not be the best choice for those just getting started. Virtual private servers are less expensive than dedicated servers and a shared server the least expensive of them all. A shared server is the most commonly used among new users because of cost and ease of use.
A shared server is one server hosting multiple different pages, as opposed to virtual private servers were each site has dedicated space on a single server. Each web page shares the same central processing unit, disc space, and memory capacity. This works well for most people but because of so many pages sharing one system it can cause the web page to load at a slower rate of speed. There is also the issue of only being able to use the resources that are actually available so if multiple pages start generating more traffic this could cut back on the available resources. When the traffic increases, upgrading to a virtual private server may be a better alternative.
Virtual private servers also share the same central processing unit. The difference between this server and the shared server is that the VPS is partitioned into individual servers giving each web page their own space. Each individual server is allotted certain amounts of memory and disc space. With the VPS the web owner also gains more flexibility in which they can download any software they need. For those ready to move away from a shared server but not ready for a dedicated server, a virtual private server is a great alternative.
