-Today's applications are required to be highly responsive and always online. To achieve low latency and high availability, instances of these applications need to be deployed in datacenters that are close to their users. Applications need to respond in real time to large changes in usage at peak hours, store ever increasing volumes of data, and make this data available to users in milliseconds.

-Recently, the surge of AI-powered applications created another layer of complexity, because many of these applications currently integrate a multitude of data stores. For example, some teams built applications that simultaneously connect to MongoDB, Postgres, and Gremlin. These databases differ in implementation workflow and operational performances, posing extra complexity for scaling applications. Azure Cosmos DB can simplify and expedite your development by being the single AI database for your applications. Azure Cosmos DB accommodates all your operational data models, including relational, document, vector, key-value, graph, and table.
