How is MongoDB used in a virtual machine?
When using virtual machines for production deployments, you should place each mongod instance on a separate host server serviced by redundant power circuits and redundant network paths. Before you can deploy a replica set, you must install MongoDB on each system that will be part of your replica set.
Can a remote client connect to MongoDB 3.6?
