Important
Azure Cosmos DB for PostgreSQL is on a retirement path and no longer recommended for new projects. Instead, use one of these two services:
For PostgreSQL workloads, use the Elastic Clusters feature of Azure Database For PostgreSQL to take advantage of horizontal scale-out and distributed PostgreSQL features within the open source Citus extension. For migration guidance, see migrate to Azure Database for PostgreSQL with Elastic Cluster.
For NoSQL workloads, use Azure Cosmos DB for NoSQL for a distributed database solution that includes a 99.999% availability service level agreement (SLA), instant autoscale, and automatic failover across multiple regions.
Azure Cosmos DB for PostgreSQL is available in the following Azure regions:
