"APPLICATION SERVERS CLUSTERING TECHNOLOGIES & TRENDS" WHITE PAPER RELEASED BY STRATEGIC FOCUS

Milpitas, CA, July 10th, 2002 … Strategic Focus, a market research and product evaluation firm based in Milpitas, California announced today the release of a white paper on "Application Servers Clustering Technologies & Trends". "We have tried to articulate as clearly as possible the basics of application server clustering, its goals and architecture" said Mr. Atar Sen Mittal, Vice-President of Technical Services at Strategic Focus and author of the white paper. "We found a need in the market where clustering strategies needed to achieve specific goals such as Scalability, Load Balancing and High Availability was not very well understood" added Mr. Mittal. The 17-page white paper takes pains to articulate these strategies and outline various clustering scenarios such as Web Clustering, Object Clustering, Web Cache Clustering, JMS clustering and JDBC Metapools Clustering.
