Hi Siji,
Hoping that this will manage the state of Video Streaming at the time of
failover.
Have you tried this before with failover video streaming ?
I have not tested such a setup before. IMO, Pacemaker cluster suite will help to provide high availability of the hosted services, in terms of monitoring and failing over the services to other nodes as the policy defined. The PEngine basically does this. It provides the logic and a component, that takes the cluster’s current state, decides on the optimal next state and produces an ordered list of actions to achieve that state.
The failover time of service in cluster will depend upon several factors such as type of resources used, time taken by the each resource in the service group to start up in case of failover/failback, network side delays. To minimize the service delay, a proper tuning will be required not only with the cluster (in terms of failover times) but also with the application which is being hosted.
Depending upon the service hosted, there can be a delay upto few seconds (solely dependent on type of application) at the time of failover which would required to be anticipated by testing the setup prior to deployment.
Kind Regards, Arvind.

Please guide, to select the right technology/solution (Ofcource

to do so. Its seems complicated for me because of the dynamic data (eg:
If
a user watching video and fail over happens, he should get seamless streaming without interruption).
Having worked on some of the aforementioned technologies+ putting virtualisation on top of it, it is almost impossible in case the box serving it fails with the current open source offerings.
Only VMware is somewhere near seamless video streaming and last I heard of it is VERY expensive.
Am exploring the possibility of using Pacemaker.
You may call me up and I can explain the issues in detail. If you do not have my number, here it is nine, nine three zero six three three eight five two.
