Web hosting service providers usually have dedicated servers located in climate-controlled buildings, connected to the internet backbone through T1/T3 lines. Anyone wishing to host his own website would approach such a hosting service which would then provide space on the dedicated server with limited administrative privileges agario private server. Since bandwidth, computer resources and RAM of the server were shared, there were some drawbacks.
Now that businesses have grown and expanded their online presence they like more facilities but most are not yet ready to afford, nor do they really need dedicated servers. An ideal compromise here is a virtual private server (VPS), which brings dedicated server like features at a far lower cost.
A virtual server is created through software for the individual customer. It runs on a single computer but there may be a number of such virtual private servers operating from the same machine, though not physically. A virtual machine that works as a server is created with its own defined and allocated RAM and hardware resources.
The customer has full administrative privileges and can manage it within these resources like he manages his own individual computer system with its own operating system and which can be rebooted without the main actual computer system server, on which it is being run, being affected. A customer can host any number of domains on a virtual private server and manage them all by himself. This technology, which was available for mainframe computers, has now trickled down to microcomputers through virtualization software developments and technologies.
The actual server manages the guest or virtual private servers, which mimics an actual PC. Resources are allocated to the virtual private servers, beyond which they cannot have any access. To all intents and purposes the virtual machine created 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 which runs virtual private servers needs to be very fast with a high amount of RAM, diskspace and resources to respond to virtualization requests and translate efficiently and quickly. Modern day specialist servers that have CPUs that can support virtualization, meet these specs making VPS easy and affordable.
As opposed to total virtual private servers we also have paravirtualized servers which recognize the host's hardware resources and are permitted to make use of them. This adds to the system overheads and the operating costs so paravirtualized servers are more expensive but are faster. Linux, BSD, Plan 9 and Solaris support paravirtualization.
For web hosting, total virtual private server set up entails less set up costs and running costs. However, response times may be slower and in case there is not much traffic, this is not a bottle neck agario. However, as you outgrow this and the website expands and there is a high amount of traffic, then you may need to reconsider virtual private server hosting and move to paravitualization or even a dedicated web hosting service. However, as on date, most websites are put up by small and medium traffic organizations, which can well manage not just one but a number of websites within a virtual private server advantageously and efficiently, making them highly cost effective.
Since you can host a number of domains and full access over emails, unlimited bandwidth and traffic, the corporates have a decided advantage in deploying not just one but a number of ecommerce sites on a virtual private servers hosting package. Data transfer rates would be 10 Mbits/sec, 100 Mbits/sec or 1000 Mbits/sec. You would also have to pay top attention to security of this virtual private server since these are unattended and you are the administrator with full control.
