Zusammenfassung
There is an urgent need for high availability and acceptable response behaviour of complex application systems available via Web. One promising solution is the distributed Web-server system with algorithms for distribution of client requests. We developed an architecture for an existing Web-based environmental information system (EIS) which offers high system availability and good performance for users in regional environmental administration and citizens of the region. The proposed solution takes into account the availability and performance of both the Web and the application layers of the system. Appropriate network architecture with redundancy and algorithms for dynamic allocation of servers in case of failure are presented. We describe the prototype implementation of the system and the first results of the test under lab conditions.
