Database for PostgreSQL
Azure Database for PostgreSQL — commitment brief
Data sourced: March 2026. Verify current figures at the Azure Pricing Calculator.
Coverage summary
Azure Database for PostgreSQL — Flexible Server supports reserved capacity for compute costs, with discounts up to ~65% vs. pay-as-you-go depending on region and performance tier. Reservations are scoped to a region, performance tier, hardware generation, and vCore count. The legacy Single Server product reached end of support in March 2025 and is retired. Additionally, the Azure Database Savings Plan (a separate 1-year savings instrument) explicitly covers Azure Database for PostgreSQL, providing flexibility for workloads where region or tier may shift.
What is covered: vCore compute costs for Flexible Server instances across General Purpose and Memory-Optimized tiers (via reservations), or infrastructure and software costs across eligible database tiers (via the Database Savings Plan).
What is not covered: Storage (billed per GB), backup storage, networking/egress, I/O operations. Compute consumption beyond the reserved vCore count is billed at pay-as-you-go rates. Reservations do not auto-renew.
Azure Hybrid Benefit
Not applicable. PostgreSQL is open-source with no Microsoft-owned software license component. AHB is not available for this service.

Reservation vs. Azure Database Savings Plan
Reservation: Scoped to a specific region, performance tier, hardware generation, and vCore count. Delivers the highest discount (up to ~65% at 3-yr) for stable Flexible Server deployments with predictable vCore footprint.
Azure Database Savings Plan (1-yr only): Hourly spend commitment covering infrastructure and software IP costs across Azure SQL Database, Azure SQL Managed Instance, Azure Database for PostgreSQL, and other eligible managed database services. Flexible — automatically applies across regions and eligible database engines. Best for organizations with mixed database estates or workloads that shift regions. Up to ~35% savings vs. pay-as-you-go.
The standard Azure Compute Savings Plan does not cover managed database services.
Regional availability
Azure Database for PostgreSQL Flexible Server reservations are available in all commercial Azure regions where the service is deployed. Reservations are region-scoped and performance-tier-scoped. Hardware generation availability varies by region — verify that your desired hardware generation is available in your target region before purchasing.
Notable exclusions: Azure Government and Azure China regions are not supported for PostgreSQL Flexible Server reservations. The retired Single Server product is not eligible for reservations in any region.
⚠️ Availability varies by SKU and region. Always verify in the Azure portal or via the Azure Retail Pricing API before purchasing.
Archera
Azure Database for PostgreSQL — Flexible Server is within Archera's commitment management scope. Archera can automate reservation purchase, monitor vCore utilization by tier, and wrap commitments in a GRI/GSP — eliminating downside risk on over-committed database compute.
