One key difference is the cost difference between running Cosmos DB and Cassandra. We have a TCO paper (https://aka.ms/documentdb-tco-paper https://aka.ms/documentdb-tco-paper) that shows that for a 1M operations/second workload, Cosmos DB is significantly 3x-10x cheaper than other systems.

And white papers are full of it. Has random things like s Cassandra cluster needs 1 full time engineer per 100 nodes. Where do you come up with this stuff?

  In my experience of Cassandra (working on an application client, not managing it), one FTE per hundred nodes is extremely generous.

    Do you mean that you typically need more engineers, or less?
    - throwanem 9y ago
      The former. One FTE per dozen nodes is more in line with what I've seen in practice.
