| A virtual server is a highly scalable and highly available server built on a cluster of real servers typically for content delivery. The architecture of cluster is transparent to end users, and the users interact with the system as if it were only a single virtual server.
For example, it can be deployed in a environment where the real servers may be interconnected by high-speed LAN or by geographically dispersed WAN. The front-end of the real servers is a load balancer, which schedules requests to the different servers and make parallel services of the cluster to appear as a virtual service on a single IP address.
Scalability is achieved by transparently adding or removing a node in the cluster.
High availability is provided by detecting node or daemon failures and reconfiguring the system appropriately.
