What is VPS

A web hosting service is a type of internet hosting service that allows an individual or an organization to make their website accessible through World Wide Web. Web hosts are companies that provide internet connectivity as well as offer space on a server that they own to be used by their clients. A server is any arrangement of hardware or software designed to provide services to clients.

A virtual private server (VPS) is a type of full featured internet hosting services. A virtual private server (VPS) also referred to as Virtual Dedicated Server is a method of splitting a server. Each virtual server can run its own full-fledged operating system, and each server can be autonomously rebooted. Physically, there are multiple host servers which are actually hosting a user's content, but the user is unaware of the hosts and it appears as a single host. A VPS server is any combination of hardware or software designed to partition a physical server computer into multiple servers.

Microsoft Virtual Server is virtualization software which allows setting up a virtual private server on a Windows operating system. A WINDOWS VIRTUAL PRIVATE SERVER (windows VPS) can be used on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Hosting a virtual private server can be done through these operating systems, thus setting up a windows VPS hosting system.

Virtual private servers bridge the hole between shared web hosting services and dedicated hosting services. A shared web hosting service refers to a web hosting service where many websites reside on a single web server connected to the Internet. Each site "sits" on its own section on the server to keep it separate from other sites. A dedicated hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. As a VPS runs its own copy of its operating system, clients have super user-level access to that operating system and can install almost any software that runs on the operating system. Certain software does not run well in a virtualized setting including: firewalls, anti-virus clients, and virtualizers themselves.

Due to their secluded nature, VPSs have become common sandboxes for possibly-insecure public services or update testing. For example, a single physical server might have two virtual private servers operating: one hosting the production-level (live) website, and a second which houses a copy of it. When updates to critical parts of software need to be made they can be tested in the second VPS allowing for detailed testing to be conducted without requiring several physical servers. A sandbox is a security mechanism for untying running programs. It is often used to execute untested code or non-trusted programs from unverified third-parties, suppliers and non-trusted users.
