Your team is growing. Who needs to manage your Azure Cosmos DB account, and who needs access to its data?

Those are separate jobs with separate permissions.

Iria Osara and Sudhanshu Khera walk through a practical access model for Azure Cosmos DB for NoSQL: assign roles to groups, give applications managed identities, scope access to the work, and make production elevation temporary.

Review your access assignments and give each person or application the permissions its job requires.
