On: Amazon DocumentDB, with MongoDB compatibility

[tootie]

Azure has been running a Mongo-compliant DB under their Cosmos umbrella for quite a while. It's not clear to me that either Azure or AWS are actually running Mongo software under the hood or rather a proprietary DB that uses the Mongo wire protocol.

Doesn’t Azure also have a not-Mongo service also called DocumentDB? Is this the same code? These cloud services are confusing enough when they don’t borrow each other’s names.

[nlawalker → Analemma_]

The Azure service formerly known as DocumentDB is now called Cosmos DB. Part of that switch was introducing multiple APIs, including a MongoDB API: https://docs.microsoft.com/en-us/azure/cosmos-db/mongodb-int...

[kerng → Analemma_]

Correct. They added more gateway compat layers in addition to Mongo and renamed it from DocumentDB to Azure CosmosDB then.

[manigandham → Analemma_]

That’s now Azure CosmosDB because it offers several different APIs for your data.

it's not mongo software, there are some incompatibilities.
