Security is very good. DB is protected from almost all type of attacks like DDOS, Illegal access, man in the middle. Encryption is top notch, Compliance with various regulatory authorities and governing bodies. Performance is also very good. Geographically distributed and replicated hence it offers low latency. The user can pay for access hence storage is almost free. Audit and security reports are easy to generate. Fine-grained access is also available. Review collected by and hosted on G2.com.

Cost is a bit on the higher side. Not fully flexible like other opensource offerings like Cassandra, MongoDB. Requires steep learning curve if you are not familiar with Microsoft stack. Review collected by and hosted on G2.com.

I liked the performance and simplicity on using it. When dealing with Json data, I often find it easier to just store it "as is", and by JSON data I can also be meaing POCOs... The broad of APIs available make it very easy to work with for pretty much everybody. Review collected by and hosted on G2.com.

Having some flaws where we cant iterate a result set returned by CosmosDB's and MongoDB API. The default size of the first batch returned by a Mongo query is 101 if I remove the $in part of the query, and I am getting an issue with insights of the data. Review collected by and hosted on G2.com.
