Building Azure DocumentDB on Open-Source Foundations | OD821

From the creator

How do you turn a high-performance open-source database engine into a globally distributed, fully managed cloud service? In this session, we go under the hood of Azure DocumentDB (prev. Azure Cosmos DB for MongoDB vCore) and explore how it is powered by the open-source DocumentDB engine. You'll learn how Microsoft built a multi-tenant cloud architecture around this core, including service orchestration, elastic scaling, workload isolation, and API compatibility.
