In dedicated hosting, every server is dedicated to the requirements of a single client. This allows complete control over the operating system, applications and the opportunity to accommodate high traffic levels. However, dedicated hosting is expensive and most businesses do not require the amount of resources and capacity, due to which they opt for VPS hosting services. VPS or virtual private hosting is an improved version of shared hosting. VPS works in a manner similar to a partitioning on PC hard drives. There is an operating system for each VPS and it is kept completely separate from the other VPSs with the help of software known as a hypervisor.
On a VPS, the problems faced in shared hosting caused by other sites hosted on the same server are eliminated. All the sites are maintained within their own VPS and hence do not affect each other. There is more flexibility with VPS than shared hosting, which limits the scope of customization, but requires less technical knowledge than dedicated hosting. It offers the reliability and quality performance that is usually available with dedicated hosting, but at a much lower cost. A VPS provides almost as much control as dedicated hosting on a smaller scale which makes it ideal for small businesses.
