This paper considers policies for distributing requests in clustered Web servers, wherein multiple server machines are conngured to function as a single high(er) performance Web server. We evaluate various load distribution policies with respect to both their ability to achieve good load balance (the primary goal) and also to their impact on the eeec-tiveness of per-machine caching. Trace-drive...

A framework for the autonomous management of clustered server systems called LAMA (Large-scale system’s Autonomous Management Agent) is proposed in this paper. LAMA is based on agents, which are distributed over the nodes and built on JINI infrastructure. There are two classes of agents: a grand LAMA and ordinary LAMAs. An ordinary LAMA abstracts an individual node and performs node-wide config...
