Web hosting service providers typically have dedicated servers located in climate controlled buildings, connected to the Internet backbone through T1 / T3 lines. Anyone wishing to host their own website would approach such a hosting service which would then provide dedicated server space with limited administrative privileges. Since bandwidth, compute resources, and server RAM were being shared, there were some drawbacks.

Now that companies have grown and expanded their online presence, they like more facilities, but most are not ready to pay yet, nor do they need dedicated servers. An ideal compromise here is a virtual private server (VPS), which offers dedicated server features at a much lower cost.

A virtual server is created through software for the individual client server hosting for USA. It runs on a single computer, but there can be several of these virtual private servers operating from the same machine, although not physically. A virtual machine that functions as a server is created with its own defined and allocated hardware and RAM resources.

The client has full administrative privileges and can manage it within these resources as it manages its own individual computer system with its own operating system and can be restarted without the actual main computer system server, on which it is running, being affected. A customer can host any number of domains on a virtual private server and manage them himself. This technology, which was available for mainframes, has now leaked to microcomputers through virtualization software technologies and developments.

The real server manages the virtual private or guest servers, which mimics a real PC. Resources are assigned to virtual private servers, beyond which they cannot access. For all intents and purposes, the created virtual machine considers these virtual resources as its own resources and uses them as an independent computer system would. The host maps or translates virtual requests. The server running virtual private servers must be very fast with lots of RAM, disk space, and resources to respond to virtualization requests and translate efficiently and quickly. Today’s specialized servers that have CPUs that can support virtualization meet these specifications, making VPS easy and affordable.

Unlike full virtual private servers, we also have paravirtualized servers that recognize the hardware resources of the host and are allowed to make use of them. This adds to system overhead and operating costs, making paravirtualized servers more expensive but faster. Linux, BSD, Plan 9, and Solaris support paravirtualization.

For web hosting, the full virtual private server setup means less setup and running costs. However, response times can be slower and in case of not a lot of traffic this is not a bottleneck. However, as you get over this and the website expands and there is a lot of traffic, you may need to reconsider hosting the virtual private server and move to paravost or even a dedicated web host. However, as today, most of the websites are created by small and medium traffic organizations, which can manage well not just one, but several websites within a virtual private server advantageously and efficiently, which makes them highly profitable.

Since it can host multiple domains and full access to unlimited emails, bandwidth, and traffic, businesses have a decided advantage in deploying not just one, but multiple e-commerce sites in one virtual private server hosting package. The data transfer rates would be 10 Mbits / sec, 100 Mbits / sec, or 1000 Mbits / sec. You should also pay the utmost attention to the security of this virtual private server, as these are unattended and you are the administrator with full control.
