Hi Alexander, Regard to N+1 redundancy feature, our team is testing with Watcher. We decided to follow 4 steps: 1. Test integrated Watcher with Ceilometer for alarm monitoring (done for basic test). We will do more tests for other alarming triggers. 2. Implementing business rules in Watcher for our instance switch-over solution (in progress). Then, we will implement code-base prototype on Watcher after that. 3. Test BM/VM instance switch-over from Nova [1] (in progress). 4. Integrate testing 1 & 3 for full solution which we are expectation. It will be perform after completed 1 & 2 & 3. If we have any issues, we will discuss with you on IRC and or IRC meeting. We really appreciate your help.
