scale their ChatGPT service – one of the fastest-growing consumer apps ever – enabling high reliability and low maintenance." – Satya Nadella, Microsoft chairman and chief executive officer</p> </blockquote> <p>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.</p> <p>The surge of AI-powered applications created another layer of complexity, because many of these applications integrate a multitude of data stores. For example, some organizations built applications that simultaneously connect to MongoDB, Postgres, Redis, and Gremlin. These databases differ in implementation workflow and operational performances, posing extra complexity for scaling applications.</p> <p>Azure Cosmos DB simplifies and expedites your application development by being the single database for your operational data needs, from <a href="https://medium.com/@marcodesanctis2/using-azure-cosmos-db-as-your-persistent-geo-replicated-distributed-cache-b381ad80f8a0" data-linktype="external">geo-replicated distributed caching</a> to backup to <a href="vector-database" data-linktype="relative-path">vector indexing and search</a>. It provides the data infrastructure for modern applications like <a href="ai-agents" data-linktype="relative-path">AI agent</a>, digital commerce, Internet of Things, and booking management. It can accommodate all your operational data models, including relational, document, vector, key-value, graph, and table.</p> <h2 id="an-ai-database-providing-industry-leading-capabilities">An AI database providing industry-leading capabilities...</h2> <h2 id="for-free">...for free</h2> <p>Azure Cosmos DB is a fully managed NoSQL, relational, and vector database. It offers single-digit millisecond response times, automatic and instant scalability, along with guaranteed speed at any scale. Business continuity is assured with <a href="https://azure.microsoft.com/support/legal/sla/cosmos-db" data-linktype="external">SLA-backed</a> availability and enterprise-grade security.</p> <p>App development is faster and more productive thanks to:</p> <ul> <li>Turnkey multi-region data distribution anywhere in the world</li> <li>Open source APIs</li> <li>SDKs for popular languages</li> <li>AI database functionalities like integrated vector database or seamless integration with Azure AI Services to support Retrieval Augmented Generation</li> <li>Query Copilot for generating NoSQL queries based on your natural language prompts (<a href="nosql/query/how-to-enable-use-copilot" data-linktype="relative-path">preview</a>)</li> </ul> <p>As a fully managed service, Azure Cosmos DB takes database administration off your hands with automatic management, updates, and patching.
