Virtual private server, a method of server hosting using virtual machines; Virtual hosting, a method that servers such as webservers use to host more than one domain name on the same computer. Virtual hosting service, a form of web hosting service where more than one instance of the same web server is hosted on a single physical server.
A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service. [1] The term "virtual dedicated server" (VDS) has a similar meaning.A virtual private server runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS.
A server is a computer that provides information to other computers called "clients" on a computer network. [1] This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single ...
The first command assigns TCP port 80 on IP address 192.168.0.1 to the virtual server. The chosen scheduling algorithm for load balancing is round-robin (-s rr). The second and third commands are adding IP addresses of real servers to the LVS setup. The forwarded network packets shall be masked (-m). [5]
In OS-level virtualization, a physical server is virtualized at the operating system level, enabling multiple isolated and secure virtualized servers to run on a single physical server. The "guest" operating system environments share the same running instance of the operating system as the host system.
Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Originally developed by Connectix , it was acquired by Microsoft prior to release.
Virtual servers do not have to be backed by opaque disk images, but can share a common file system and common sets of files (through copy-on-write hard links). This makes it easier to back up a system and to pool disk space amongst virtual servers. Processes within the virtual server run as regular processes on the host system.
Name-based virtual hosts use multiple host names for the same IP address. A technical prerequisite needed for name-based virtual hosts is a web browser with HTTP/1.1 support (commonplace today) to include the target hostname in the request. This allows a server hosting multiple sites behind one IP address to deliver the correct site's content.
