Azure Cosmos DB
Develop AI-powered low-latency apps and agents with a fully managed and serverless NoSQL vector database at any scale.
OVERVIEW
Develop AI-powered apps at any scale
- Power copilots and multi-agent apps with NoSQL and vector data, and generate queries by asking questions using natural language.
- Simplify AI apps by storing and querying vectors and NoSQL data efficiently using a serverless vector database—powered by DiskANN.
- Leverage hybrid search to combine vector search, full-text search (BM25), and semantic ranking to deliver fast, low-latency results that are both context-aware and keyword-relevant within the same JSON document model in your Cosmos database.
- Integrate NoSQL and vector data directly into your applications through a unified JSON document model, enabling context-aware AI apps and multi-agent experiences with support for developer tools and AI frameworks.
- Scale out your Cosmos data and throughput with automatic partitioning as demand grows—without impacting availability or requiring manual intervention. Ideal for applications with unpredictable growth and high throughput demands, including real-time, globally distributed, and AI-driven workloads and SaaS applications that must scale seamlessly without downtime or operational overhead.
- Build highly responsive apps with <10ms latency SLA and up to 99.999% availability across multiple regions. Best suited for modern applications such as SaaS platforms, intelligent apps, and real-time services that need low latency at global scale.
- Maintain high availability for single-write region accounts by automatically failing over at the partition level, minimizing disruption and eliminating manual intervention.
- Spend less time managing databases and more time building with a fully managed NoSQL database designed for rapid development. Easily evolve your data model using schema-less JSON documents and automatic indexing—so you can create real-time applications, AI-powered copilots, multi-agent systems, personalized user experiences, and globally distributed SaaS platforms.
- Build apps in Python, Node.js, Java, .NET, Go, and more with full Azure Cosmos DB SDK support. Go from prototype to production faster with tools designed for modern NoSQL applications, including real-time, cloud-native, and AI-powered scenarios.
- Start quickly with serverless NoSQL for JSON data in Azure Cosmos DB. No capacity planning required, and you pay only for what you use. As your application grows, seamlessly transition your serverless NoSQL database to provisioned throughput with dynamic autoscale to handle increasing demand.
- Start building with a free tier option, then avoid overprovisioning as you scale by using dynamic autoscale to adjust throughput in real time. Optimize cost and performance for NoSQL and JSON workloads—handling spikes automatically while paying only for the capacity you need.
- Mirror Azure Cosmos DB data into Microsoft Fabric to enable near-real-time analytics, AI, and reporting without extract, transform, and load (ETL) processes. Combine operational data with other sources in OneLake for deeper insights.
- Use Azure Functions, AKS, and Azure Container Apps to process Azure Cosmos DB change feed events in real time—triggering workflows, microservices, and analytics without complex data polling or ETL.
- Store agent conversations and model interactions securely in Azure Cosmos DB, and gain enterprise control, observability, and improved multi-turn AI experiences.
