With the use of virtualization software, physical servers can be partitioned into multiple 'virtual' servers where each virtual server looks and acts like an individual dedicated server. Virtual Servers can run their own operating systems which means that each system can be administered independently - including system re-boot.
A Virtual Private Server (VPS) is one instance of a Virtual Server. It has its own operating system, applications and data which are all isolated from all other data that resides on the physical server. A Virtual Private Server can enable you to leverage the benefits of dedicated servers at a fraction of the cost.
You can take advantage of the numerous benefits of VPS:
Ease of use
Lower total cost of ownership
The one benefit, however, that really stands out for Virtual Private Servers is 'flexibility'. Given that VPS's have their own
operating environments, you can install you own operating system / version, you can add and remove software applications at will and you can modify you environment for optimum performance. A VPS allows you to customize your users' experience which, in turn, can be used as a competitive advantage.
As business, web traffic, increases, overall performance and throughput can be compromised. Any business owner who anticipates growth should consider a VPS. Any business owner who needs specific / custom applications installed on their server, but is not able or willing to fund the purchase and maintenance of a dedicated should consider a VPS.
A Virtual Private Server is a partition on a physical server. The physical server can be divided into numerous virtual partitions which, in turn, will distribute the cost and overhead between the virtual servers. Because the cost of the physical server is essentially shared between the VPS's, the servers that are typically used in a VPS environment have greater performance capabilities and greater capacity than dedicated servers. For most small business owners the cost of a comparable, dedicated, server is cost-prohibitive.
