Virtual Private Server (VPS) Hosting for businesses

Why and when a business needs VPS Hosting

A business can host a website or web application on a shared server. Shared hosting is cheaper for the business and does not require the technical skills necessary for managing a web server. VPS hosting is needed when a web application requires high CPU and/or memory (RAM) usage or if the web host refuses to run the application on a shared hosting server due to the application's technical requirements.

VPS hosting is preferred over shared hosting, because it allows web applications to run faster in their isolated environment. A business can install a web application on their VPS without having to worry about whether the web host would allow the permissions or components necessary for running their application.

VPS hosting requires that the customer set up their own mail service, install their database, do system updates, secure the system and do backups of the VPS server. Some web hosts provide these services on a monthly fee basis or as per request basis. Overall, VPS hosting makes sense for demanding applications, or applications needing special permissions or components.

Technicalities of a VPS

A Virtual Private Server is so called because it allows a web application to run in its private container without affecting other containers on the same physical server. A VPS runs just like a dedicated server, except for the high cost one pays for a dedicated server.

In a virtualized environment, a physical server runs a hypervisor application which executes the requests of the operating system running in a VPS container and which allocates and releases resources on the physical server. An operating system running on the VPS, may or may not know of the hypervisor application. When it does not know of the presence of the hypervisor application, this is called being ‘fully virtualized’. This requires the CPU to support virtualization. In a fully virtualized environment, the hypervisor takes requests from the VPS's operating system and maps them to physical resources. Microsoft Hyper-V Server is an example of software enabling full virtualization.

When the VPS's operating system knows about the hypervisor, it can directly address the resources on the physical server; the role of the hypervisor is to control those requests. Such an environment is said to be paravirtualized. Citrix XenServer is an example of software enabling paravirtualization.

Most hypervisors support different operating systems on the VPS. This means that on a physical server, one VPS can run the Windows operating system and another the Linux operating system and variants. When the Windows operating system is running, it is called a Windows VPS. If the Linux operating system is installed on it, it is called a Linux VPS.
