Moving to TLS 1.2 for Azure Cosmos DB: Ensuring Secure Connections
Security and reliability are at the core of modern cloud applications. To strengthen data protection and align with industry best practices, we encourage all Azure Cosmos DB customers to transition to TLS 1.2. This post explains why this change is important, how to make the transition, and the benefits it brings to your applications. Why Move to TLS 1.2? Transport Layer Security (TLS) is a critical component in securing data transmitted over networks. TLS 1.2 offers enhanced security features compared to its predecessors, TLS 1.0 and 1.1. By moving to TLS 1.2 or later, you ensure that your data is protected wi...
DocumentDB is Gaining Momentum in the Open-Source Database World

Use Azure Cosmos DB as a Docker container in CI/CD pipelines
There are lot of benefits to using Docker containers in CI/CD pipelines, especially for stateful systems like databases. For example, when you run integration tests, each CI job can start the database in an isolated container with a clean state, preventing conflicts between tests. This results in a testing environment that is reliable, consistent, and cost effective. This approach also reduces latency and improves the overall performance of the CI/CD pipeline because the database is locally accessible. The Linux-based Azure Cosmos DB emulator is available as a Docker container and can run on a variety of platf...
Doctors generate faster, more accurate medical charts with Sayvant and Azure Cosmos DB
This article is guest authored by Justin Mardjuki, CEO, Sayvant. Emergency rooms and urgent care facilities handle an estimated 350 million visits each year. Acute care environments are fast-paced, unpredictable, and high stakes. In these settings, providing care quickly is paramount. That’s why we created Sayvant, the leading clinical documentation AI solution for acute care. Sayvant helps clinicians generate accurate, defensible medical charts in seconds, enabling them to focus on delivering patient care instead of administrative tasks like documentation. Sayvant automates the creation of clinically accurate...

Cosmos DB Embeddings Generator Sample
Ever since our first preview announcement for vector indexing and support for DiskANN and then again when we announced the GA for these features, customers have been asking us to make it easier to generate Azure OpenAI embeddings on their data in Azure Cosmos DB. So we did just that and created the Azure Cosmos DB Embeddings Generator sample application and hosted it on GitHub. This sample shows how to use an Azure Cosmos DB Trigger and Output Binding in Azure Functions to automatically generate Azure OpenAI embeddings on a new or updated item, then save it back to the same item in Cosmos DB. There is bo...
An introduction to Multi-Agent AI apps with Azure Cosmos DB and Azure OpenAI
Azure Cosmos DB was named by Bloomberg as the no. 1 Database of choice for Retrieval Augmented Generation (RAG) and Large Language Model (LLM) customization. It is used by OpenAI to scale it’s ChatGPT service, and by many thousands of customers worldwide, serving billions of end-users with globally distributed apps at planet scale. In this blog we will explore a simple example for lightweight multi-agent orchestration in Python using OpenAI Swarm. We’ll also see the benefits of being able to use Azure Cosmos DB as both a vector store and an operational database. What are multi-agent apps? Multi-agent AI apps...
