Hi Parvin, Fault tolerant architecture is something you need to decide on your requirement. At some point of time there may require some manual intervention to recover from crash. You need to see how much percentage you could support fault tolerant. It certainly may not be 100. We could handle situation of network failure but hard to handle situation of crashes.
Consider you have one master and two slaves. You could have load balancer between slaves, so that you could do round-robin or fail-over between slaves. If you are not using load balancer then you should handle this in your application. If the master crashes, then you may need to rebuild the index. Chances are less likely.
