Pricing behavior (not a price list)
These points describe when users typically pay more and what usage patterns trigger upgrades.
Actions that trigger upgrades
- Need managed Postgres aligned to Azure enterprise governance
- Need a managed relational baseline for multiple apps/teams
- Need a production baseline aligned to Azure operations as governance and audit requirements increase
What gets expensive first
- Operational standards are still required to keep reliability and performance predictable
- Switching cost increases with deep Azure integration
- Cost predictability still requires budgets/labels and ownership discipline
Plans and variants (structural only)
Grouped by type to show structure, not to rank or recommend SKUs.
Plans
- Compute - provisioned instances - Billed by instance size/region; HA and read replicas add cost.
- Storage + I/O - separate drivers - Storage, backups, and I/O/operations can materially change total cost.
- Availability - pay for resilience - Multi-AZ/high availability configurations increase reliability and spend.

Next step: constraints + what breaks first
Pricing tells you the cost cliffs; constraints tell you what forces a redesign.
