The Virtual Service Grid: an architecture for delivering high-end network services

摘要

This paper presents the design of a new system architecture, Virtual Service Grid (VSG), for delivering high-performance network services. The VSG is based on the concept of the virtual service which provides location, replication, and fault transparency to clients accessing remotely deployed high-end services. One of the novel features of the virtual service is the ability to self-scale in response to client demand. The VSG exploits network and service information to make adaptive dynamic replica selection, We have decisions.
