what separates VPS from Dedicated
Virtual private servers (VPS) – have historically offered some middle ground between shared web hosting services and dedicated hosting services, both in control and cost, but recently the gap in cost between virtual and dedicated servers has diminished … making upgrades from shared to dedicated web hosting very attractive.

A virtual private server separates you from – other customers on a physical web server, running on a copy of its own operating system, but it shares CPU and RAM resources of the physical web server with other VPSs running on that server.

A dedicated server, on the other hand, is – a physical web server leased and controlled by the end client, without sharing physical CPU and RAM resources with other sites. Its very much like owning your own server, without the huge capital asset investment. Most hosts offer a mix of unmanaged versus managed services for dedicated servers. Unmanaged plans typically offer the basics – the hardware, operating system, control panel and Internet connection.

In a VPS, a single physical server is partitioned – so that it appears as multiple servers. The physical server boots normally, then runs a program to boot each VPS within a virtualization environment.

There are two kinds of virtualizations – software and hardware based. Software based environments share the same kernel and require the main node’s resources. In a web hosting environment, quota incrementing and decrementing in real time is possible without restarting the node. In a hardware based virtualization, real hardware resources are partitioned, eliminating burst or real time quota modification. This lends to a (potentially) more secure environment.

With a dedicated server, you have – more flexibility and control. Dedicated servers have historically been the server of choice for complex business or high end eCommerce sites, but have recently become very popular substitutes for VPS servers and less complex solutions.

The bottom line: Moving websites from a shared environment to either a VPS or dedicated server is a significant event. Its a major upgrade in the IT infrastructure supporting your business. Whereas the move from shared to dedicated was historically cost-prohibitive, and VPS offered some middle ground, technology has rapidly evolved to narrow that gap.

Upgrading should be based on more than cost

Upgrading your IT technology, in this case to VPS or Dedicated is now a business decision based on more than cost. It’s based on resources you control that will map your business success for years or decades.
