Azure Cosmos DB - Database for the AI Era

  • Article

APPLIES TO: NoSQL MongoDB Cassandra Gremlin Table

Today's applications are required to be highly responsive and always online. They must 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. To achieve low latency and high availability, instances of these applications need to be deployed in datacenters that are close to their users.

Azure Cosmos DB is a fully managed NoSQL database for modern app development. Single-digit millisecond response times, and automatic and instant scalability, guarantee speed at any scale. Business continuity is assured with SLA-backed availability and enterprise-grade security. App development is faster and more productive thanks to turnkey multi region data distribution anywhere in China, open source APIs and SDKs for popular languages. As a fully managed service, Azure Cosmos DB takes database administration off your hands with automatic management, updates and patching. It also handles capacity management with cost-effective serverless and automatic scaling options that respond to application needs to match capacity with demand.

You can use the Azure Cosmos DB free tier to get an account with the first 1000 RU/s and 25 GB of storage free.

...for more than just AI apps

Besides AI, Azure Cosmos DB should also be your goto database for a variety of use cases, including retail and marketing, IoT and telematics, gaming, social, and personalization, among others. Azure Cosmos DB is well positioned for solutions that handle massive amounts of data, reads, and writes at a multiple-region scale with near-real response times. Azure Cosmos DB's guaranteed high availability, high throughput, low latency, and tunable consistency are huge advantages when building these types of applications.

For what kinds of apps is Azure Cosmos DB a good fit?
  • Flexible Schema for Iterative Development. For example, apps wanting to adopt flexible modern DevOps practices and accelerate feature deployment timelines.
  • Latency sensitive workloads. For example, real-time Personalization.
  • Highly elastic workloads. For example, concert booking platform.
  • High throughput workloads. For example, IoT device state/telemetry.
  • Highly available mission critical workloads. For example, customer-facing Web Apps.
For what kinds of apps is Azure Cosmos DB a poor fit?
  • Analytical workloads (OLAP). For example, interactive, streaming, and batch analytics to enable Data Scientist / Data Analyst scenarios. Consider Microsoft Fabric instead.
  • Highly relational apps. For example, white-label CRM applications. Consider Azure SQL, Azure Database for MySQL instead.
