Azure Cosmos DB: Globally Distributed Databases Made Simple

Public clouds are quickly making massive-scale computing capabilities available to an ever-larger population of developers and data professionals. These computing capabilities are no longer a playground restricted to a small handful of large-scale internet services organizations.

In Rimma's talk this year, she will provide a deep understanding into Azure Cosmos DB, Microsoft’s globally distributed, multi-model database service that's been 7 years in the making. We’ll take an under the bonnet look at the system and discuss various design trade-offs that had to be made to allow customers to elastically and horizontally scale both throughput and storage globally.

We’ll also discuss how the system can provide single digit millisecond latencies with 99.99% high availability. I will also share some of our real-world experiences in operating a globally distributed database service and will touch on how Azure Cosmos DB compares to the competition (including Google Spanner, AWS DynamoDB, Cassandra, MongoDB and others).

Talk objectives

Understand why systems like Azure Cosmos DB are taking the industry by storm.
