SYSTEMS AND METHODS FOR SERVER CLUSTER APPLICATION VIRTUALIZATION

摘要

Application instances can be virtualized and operate in a fault tolerant andload-balanced meansacross a cluster of servers while still maintaining access to a common pool ofdata. Eachapplication instance is instantiated so to operate on top of a virtual hostthat possesses a distinctvirtual Internet protocol address. Each node within a server clusterenvironment can possess oneor more virtual hosts wherein upon server failover the virtual host and itsassociated virtualInternet protocol address can be relocated to another server withoutdisturbing the instantiationof the application on the virtual host.
