What type of MongoDB deployment would you like to build?

Three ways we can deploy mongodb

Standalone Instance 

 A standalone MongoDB provides a single copy of your data and is appropriate for        projects where data loss is not a concern.

Replica Set

A replica set is a group of MongoDB instances that host the same data set. A replica set provides both redundancy and high availability.

Sharded Cluster

Sharding is a method for storing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations.
