I am trying to make mongodb set-up, I am trying to analyze risk factor involved in it.
My configuration in testing environment is
Routing server------> Config Server ------- > Shard01
Shard02
Shard03
My routing server and config server is running on same machine. Shard01, Shard02, Shard03 are running on three different machine respectively. I want to analyze what all risk factors are involved in this system. For example, one scenario is if any Shard machine is down application will stop?
