Azure Cosmos DB – Unified AI Database

APPLIES TO: NoSQL MongoDB Cassandra Gremlin Table PostgreSQL

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.

Azure Cosmos DB is a fully managed NoSQL and relational database for modern app development including AI, digital commerce, Internet of Things, booking management, and other types of solutions. Azure Cosmos DB offers single-digit millisecond response times, automatic and instant scalability, along with guaranteed 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 the world
  • Open source APIs
  • SDKs for popular languages.
  • AI database functionalities like native vector search or seamless integration with Azure AI Services to support Retrieval Augmented Generation

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.

If you are an existing Azure AI or GitHub Copilot customer, you may try Azure Cosmos DB for free with 40,000 RU/s of throughput for 90 days under the Azure AI Advantage offer.

If you are not an Azure customer, you may use the 30-day Free Trial without an Azure subscription. No commitment follows the end of your trial period.

Alternatively, you may use the Azure Cosmos DB lifetime free tier with the first 1000 RU/s of throughput and 25 GB of storage free.

Azure Cosmos DB is more than an AI database

Besides AI database, Azure Cosmos DB should also be your goto database for web, mobile, gaming, and IoT applications. Azure Cosmos DB is well positioned for solutions that handle massive amounts of data, reads, and writes at a global 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. Learn about how Azure Cosmos DB can be used to build IoT and telematics, retail and marketing, gaming and web and mobile applications.

Key Benefits

Here's some key benefits of using Azure Cosmos DB.

Guaranteed speed at any scale

Gain unparalleled SLA-backed speed and throughput, fast global access, and instant elasticity.

  • Real-time access with fast read and write latencies globally, and throughput and consistency all backed by SLAs
  • Multi-region writes and data distribution to any Azure region with just a button.
  • Independently and elastically scale storage and throughput across any Azure region – even during unpredictable traffic bursts – for unlimited scale worldwide.

Simplified application development

Build fast with open-source APIs, multiple SDKs, schemaless data and no-ETL analytics over operational data.

  • Deeply integrated with key Azure services used in modern (cloud-native) app development including Azure Functions, IoT Hub, AKS (Azure Kubernetes Service), App Service, and more.
  • Choose from multiple database APIs including the native API for NoSQL, MongoDB, PostgreSQL, Apache Cassandra, Apache Gremlin, and Table.
  • Use Azure Cosmos DB as your unified AI database for data models like relational, document, vector, key-value, graph, and table.
  • Build apps on API for NoSQL using the languages of your choice with SDKs for .NET, Java, Node.js and Python. Or your choice of drivers for any of the other database APIs.
  • Change feed makes it easy to track and manage changes to database containers and create triggered events with Azure Functions.
  • Azure Cosmos DB's schema-less service automatically indexes all your data, regardless of the data model, to deliver blazing fast queries.

Mission-critical ready

Guarantee business continuity, 99.999% availability, and enterprise-level security for every application.

  • Azure Cosmos DB offers a comprehensive suite of SLAs including industry-leading availability worldwide.
  • Easily distribute data to any Azure region with automatic data replication. Enjoy zero downtime with multi-region writes or RPO 0 when using Strong consistency.
