MongoDB Sharded Cluster & HA – How to Design your Topology

MongoDB Sharded Cluster is very well established to handle huge amounts of data across geographically separate data centers. Sharding the data across the shards evenly or specific to region/data centers based on the application requests are important. But sometimes the sharded cluster setup is not well designed, which leads to data being distributed improperly across shards so the application fails to serve the request within the desired turnaround time. Also HA design within Sharded Cluster is equally important to avoid any downtime. In this talk, we will see how to design your Shared Cluster topology + HA to make the most out of it.
