virtual server

[witly]

:rolleyes: :rolleyes: Virtual server is basically a highly scalable as well as available server that is built on a cluster of real servers.

They are load balancers which are sometimes interconnected by high-speed LAN / WAN and can dispatch requests to the different servers and services that are parallel of the cluster which appears as a virtual service on a IP address thereaftyer request dispatches that can use IP load balancing technolgies / application-level load balancing technologies. System Scalability is achieved by adding or removing nodes in the cluster. The availability is provided by detecting node or daemon failures and reconfiguration of the system appropriately. Server cluster architecture is fully transparent to end users, the users can interact with the cluster system.
