Azure Cosmos DB, a globally distributed database

This isn't a new database. This is a rebranding of the generically-named Azure DocumentDB, plus some new features.

Not exactly. DocumentDB was primarily a document store. Cosmos allows you to store graphs and KV pairs as well.

Is it open source? Why do I care? The same reason I don't use AWS or Google Cloud only datastores: I want to avoid vendor lockin.

Agreed - seems like a rebranding in response to Google Cloud Spanner DB announcement a couple of months back. Microsoft's marketing seems to be pushing some of the same outcomes in the ad copy.

this is a little bit hard to believe. Inter region Ping can even take longer than 15ms... I guess this SLA is for eventual consistency model not strong consistency model

Probably not

You might not.

Sounds like this isn't the product for you then.

Is that a surprise?

My questions were rhetorical. One reason I post my thoughts here is because companies like MS are on HN. It's useful to know why people don't want to use your product or are hesitant to do so. Besides, MS has been doing a lot of surprising things lately post-Ballmer.
