Mariano Vazquez explains how to configure MongoDB replica sets on Microsoft Azure and how that works:
- MongoDB will run the native binaries on a worker role and will store the data in Windows Azure storage using Windows Azure Drive (basically a hard disk mounted on Azure Page blobs)
- The good thing about using Azure Storage is that the data is georeplicated. It will also make backup easier because of the snapshot feature of blob storage (which is not a copy but a diff).
- It will use the local hard disk in the VM (local resources in the Azure jargon) to store the log files and a local cache.
- You can scale out to multiple Mongo Replica Sets by increasing the instance count of the MongoDB role
