Abstract

A virtual server is a server whose location in an internet is virtual; it may move from one physical site to another, and it may span a dynamically changing number of physical sites. In particular, during periods of high load, it may grow to new machines, while in other times it may shrink into a single host, and may even allow other virtual servers to run on the same host. This paper describes the design and architecture of Symphony, a management infrastructure for executing virtual servers in internet settings. This design is based on combining CORBA technology with group communication capabilities, for added reliability and fault tolerance.
