What is WANdiscos key advantage over other multi-site solutions?
Ans. WANdisco’s unique active-active replication technology is its key advantage. Unlike competing multi-site solutions, WANdisco doesn’t rely on a central transaction coordinator that can easily become a single-point-of-failure. Instead, WANdisco is installed with each development site’s Subversion or CVS source code repository replica. Each source code repository replica then becomes an active node on the WAN with its own distributed coordination engine (DCone™). These DCones accept local updates and propagate them to all of the other repository replicas in real-time. Everyone is effectively working from the same copy of the source code repository regardless of location. This means that development procedures don’t have to change when development moves offshore. Developers don’t sit idle waiting for large builds to complete when work from multiple sites is integrated to meet project milestones. Problems are detected earlier. Less time is spent in QA.
