Azure Cosmos DB – an opportunity to manage a multi-continental database

Azure Cosmos DB is Azure's main NoSQL offering. Azure Cosmos DB has its own interface that is a subset of SQL, but it can be configured with a MongoDB interface. It can also be configured as a graph data model that can be queried with Gremlin. Cosmos DB allows replication for fault tolerance and read scale-out, and replicas can be distributed geographically to optimize communication performance. Moreover, you can specify which data center all the replicas are placed in. The user also has the option to write-enable all the replicas so that writes are immediately available in the geographical area where they are done. Write scale-up is achieved with sharding, which the user can configure by defining which properties to use as shard keys.
