What is VPS Hosting?

VPS is a term used by internet hosting companies in reference to a virtual machine. The term is used for highlighting that the virtual machine, while running in software on the same physical computer hardware as other users virtual machines, is functionally equivalent to a separate physical computer that is dedicated to that individual user's needs. It has the privacy of a separate physical computer and can be configured to run as a server computer (i.e. to run server software).

In addition to reducing hardware and power expenses, virtualisation allows businesses to run their legacy applications on older versions of an operating system on the same server as newer applications.

Each virtual server can run its own full-fledged operating system and can be independently rebooted.

How does VPS Hosting work?

The practice of partitioning a single server so that it appears as multiple servers has long been common practice.

The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical serve, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor.

In a fully virtualized environment, the guest is presented with an emulated or virtualized set of hardware and is unaware that this hardware is not strictly physical. The hypervisor in this case must translate, map, and convert requests from the guest system into the appropriate resource requests on the host, resulting in significant overhead. Almost all systems can be virtualized using this method, as it requires no modification of the operating system. However a CPU supporting virtualization is required for most hypervisors that perform full virtualization.

Virtual private servers bridge the gap between shared web hosting services and dedicated hosting services, giving independence from other customers of the VPS service in software terms but at less cost than a physical dedicated server. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS. Certain software does not run well in a virtualized environment, such as virtualizers themselves; some VPS providers place further restrictions, but they are generally lax compared to those in shared hosting environments. Due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.

What are the benefits of VPS Hosting?

VPS hosting provides the power and equivalent functionality of a high-end dedicated server at a much cheaper cost. VPS gives you the flexibility and the independence of a dedicated hosting service for the price of a high end shared hosting service. It gives you CPU and RAM for your website and that you don’t have to share with anyone else.

In a shared hosting environment if there is a problem with one website it can cause the server to crash and take down all the other websites. This is not an issue when you have a VPS machine. In a VPS environment only the problem website will go down leaving the other websites unaffected.

When there are high traffic websites, in a shared hosting environment, they hog all the server’s resources causing the other websites to be unreachable on the server. In a VPS environment this will not happen as each website can only access the resources that are allocated to it.

VPS hosting has become very popular because it is now a very affordable hosting solution. The advantages of VPS are cost, functionality and flexibility.  VPS hosting provides a 100% individual machine, you can reboot anytime you want, without affecting any other user.

With a VPS system the user can feel totally in control of the server operations. The user can alter the RAM allocation, Space requirement, the Operating System used etc. on runtime itself. Normal shared web hosting techniques employ a supervisor application which monitors the resources used by each domain user, Ram utilized/unutilized, CPU Processing efficiency, bandwidth used etc. But these features are not enough to monitor a server in which virtual partitions have been created by the process of virtualization.

VPS needs a class of superior supervisor applications which have been named Hypervisors. There are two ways of loading a Hypervisor: – One can, either load it on the machine directly and allow the OS selected (from among several choices) to be loaded onto the hypervisor; or load the hypervisor onto a parent OS and serve as a link to secondary OS. The former method involves booting the hypervisor first and then loading OS on top of it (kind of like the GRUB but with increased functionality) and the latter lets hypervisor take over from the parent OS only when initiated. Two types of hypervisors are used commonly: The HyperV for Windows servers and the VMware for Linux based servers.

VPS has other features to boast about: its better space efficiency (increased server space utilization) compared to that of most dedicated servers. Unlike shared web hosting the owner of a partition in VPS does not feel the effects of the changes carried out elsewhere in the server. Moreover the cost factor is also very important. VPS packages are considerably cheaper than a similar Dedicated Server package.

Windows VPS Hosting vs Linux VPS Hosting

Windows and Linux VPS servers serve different audiences. This is because Windows and Linux are two different operating systems. Linux is an open source operating system where as Windows is a commercial operating system.

Some of the main differences between the two VPS servers:

Support for classic ASP and ASP.NET
The main advantage of using a Windows VPS server is its support of classic ASP and ASP.NET web pages and scripts. Linux VPS does not cater for this.

• Remote Desktop Access
Remote desk access helps by giving direct GUI access. This can make server management easier. Linux VPS server can be hard to manage because the only way is via SSH, which is a text based interface. A good knowledge of the necessary commands is required to keep Linux VPS in good order.

• Support for Microsoft SQL Server and Microsoft Access
The only web hosting service that can be used if your website makes use of Microsoft SQL Server or Microsoft Access is the Windows VPS.

• Lower costs
Linux VPS servers are more suited to users who do not have demanding needs and have a smaller budget. The Linux VPS server is cheaper than the Windows VPS server of the same specification.

• Reliability
Linux VPS servers can be heavily optimized and installed to use less system resources. The server will use less system resources and you can be sure that you have something to fall back on if your VPS server suffers a load spike.
When compared to a dedicated server a VPS server hosting be it Windows or Linux VPS server will meet your requirements more effectively in a cheaper way.
