Azure Cosmos DB for MongoDB vCore now supports private endpoint, enhancing security and connectivity within Azure. This feature allows virtual network (VNet) hosts to securely access data over Private Link, ensuring traffic between the VNet and database remains on the Microsoft backbone network, away from public internet exposure. Users can select private access during cluster setup or switch from public to private access anytime, leveraging Azure Private Link's benefits for secure, efficient database connections.
