Abstract [en]

This work is about achieving fault tolerance in real-time groupware implemented for theweb. These systems are often implemented using an architecture that involves a single pointof failure. The problem is the lack of solutions that solve this problem that can easily beapplied to implementations. The question is whether such a solution can be created and howit would perform. Some research has previously been conducted on this subject; however,the solutions proposed often have significant weaknesses and lack published results on howreliable the solutions actually are. In this work, a new solution is created and presented,which does not include the weaknesses as the previously suggested solutions. An experimentis conducted involving the implementation of a groupware application using common webtechnologies with the proposed solution applied and running simulations with fault injectionas to measure to what degree the solution is able to tolerate faults in different scenarios. Theresults show that the solution is able to achieve a higher fault tolerance.
