On: Azure Cosmos DB, a globally distributed database

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

The latency SLAs are within the same Azure region. You can distribute your data across any of the 30+ regions that Azure is available in. Your apps always read from the local/closest region with the homing APIs.

That didn't answer the question: will all regions be always consistent?

We would invite you to explore the consistency levels available in Cosmos DB. As a developer you can choose what makes most sense in distributed scenario. https://docs.microsoft.com/en-us/azure/documentdb/documentdb... Eventual is one end of the consistency. But then consistent prefix, session (if you can control) and bounded staleness all can play a role.

Tunable consistency. Very cool.
