Azure is expanding its Postgres portfolio with managed services for developers and teams of all sizes. Here are the main Postgres options on the Azure Marketplace:

• Azure Database for PostgreSQL: First managed Postgres service, with Single Server and Flexible Server flavors. Flexible Server is the recommended option, offering features like multi-AZ deployments, customizable maintenance windows, VNet integration, and autoscaling.
• Neon Serverless Postgres: A serverless Postgres solution for teams to ship modern applications faster. It separates compute and storage, supports database branching, and automatically scales resources based on usage.
• Azure Cosmos DB for PostgreSQL: A distributed Postgres database service for large-scale, high-performance applications. It uses a shared-nothing architecture and offers features like automatic sharding and built-in replication.
• EDB Postgres AI Cloud Service: An offering from EnterpriseDB with Oracle compatibility. It provides features like Oracle syntax support, replication, and optimizations for machine learning workloads.

Each option has its own features and is suitable for different scenarios. The best choice depends on the application's requirements, team size, and budget. Explore the options in the Azure Marketplace to make the right decision.
