I would like to understand what is the most common architecture deployed with MongoDB.
For example, what kind of deployment is most common:
( a ) Sharded Clusters
( b ) Replica Set (no shards) with [ n ] members
I understand that a shard cluster is the way to go to scale-out your database, but what would be the performance breakdown to start a sharded cluster?
Do you recommend to start a database as sharded database?
