## How Azure Database pricing works

Azure Database for PostgreSQL and MySQL (Flexible Server) bills each database by its compute tier under two models. On-demand is pay-as-you-go with no commitment, shown as a monthly figure (hourly rate x 730). Reserved instances commit you to a tier for one or three years in exchange for a lower rate; the effective monthly cost is the reservation amortized over the term.

There are three tiers. Burstable (B-series) is priced per fixed machine size for low or spiky workloads. General Purpose (Ddsv5, 4 GB per vCore) and Memory Optimized (Edsv5, 8 GB per vCore) are priced per vCore, so cost scales with the size you pick. Reserved terms cut compute by roughly 38% (1-year) and 55% (3-year); Burstable has no reserved option. The interactive table at https://www.bytebase.com/dbcost/azure-flexible-server-pricing lets you switch region and engine and sort by any column.

The price shown is for compute only. Storage, provisioned IOPS, zone-redundant high availability (which roughly doubles compute), backups, and outbound bandwidth are billed separately and vary by region. Rates here are the current-generation v5 series, single-zone.

## Azure Database pricing FAQ

### How much does Azure Database for PostgreSQL / MySQL cost?

On-demand Azure Database Flexible Server starts around $12/month for a Burstable B1ms instance and scales to several thousand per month for the largest Memory Optimized machines (PostgreSQL, East US). That is compute only - storage, high availability, backups, and bandwidth are billed separately.

### What is the difference between Burstable, General Purpose, and Memory Optimized?

Burstable (B-series) gives a baseline of CPU with the ability to burst - best for dev/test and low-traffic workloads. General Purpose (Ddsv5, 4 GB per vCore) is the balanced tier for most production databases. Memory Optimized (Edsv5, 8 GB per vCore) suits memory-hungry workloads.

### What is the difference between on-demand and reserved Azure pricing?

On-demand has no commitment and is billed per hour. Reserved instances commit you to a compute tier for 1 or 3 years and cut the effective monthly cost by roughly 38% and 55%. Burstable has no reserved option.

### Does the price include storage and high availability?

No. The price is for the database instance (compute) only. Storage, provisioned IOPS, zone-redundant high availability (which roughly doubles compute), backups, and outbound bandwidth are billed separately by Azure.

### What is the cheapest Azure Database instance?

The Burstable B1ms is the cheapest option (about $12/month on-demand in East US). For steady production workloads a General Purpose D-series is usually the better value per vCore.

### Is Azure Database pricing the same in every region?

No. Rates vary by Azure region; East US is usually among the cheapest.
