Cram Sheet — Design governance
Place boundaries, policy, cost ownership, compliance evidence, and privileged access at the right scope. Use this sheet after the linked lessons: it is a retrieval map and decision aid, not a substitute for the worked examples.

- Recommend and reject
Decision matrix
| Requirement shape | Start with | Qualifying rule |
|---|---|---|
| Enterprise hierarchy | Management groups and subscriptions | Organise by durable governance differences |
| Prevent configuration drift | Azure Policy and initiatives | Audit first, then deny/modify/deploy with remediation |
| Protect lifecycle operations | Resource locks and deployment stacks | Do not confuse protection with authorization |
| Govern access lifecycle | PIM, access reviews, entitlement management | Remove standing and stale access |
The phrase start with matters. A default is only defensible after checking all hard constraints: region and SKU support, protocols, scale, availability, security, residency, recovery, skills, and operating ownership. When two rows appear in one scenario, compose them rather than forcing one service to solve every concern.
Fast design method
- Name the workload boundary and the users or systems that cross it.
- Extract measurable requirements: latency, throughput, volume, RTO/RPO, consistency, outage window, and retention.
- Mark security and governance constraints: identity, network reachability, encryption, residency, audit, and separation of duties.
- Select the simplest viable default from the matrix.
- Test it against failure domains, scale transitions, deployment, monitoring, and cost.
- State the nearest alternative and the one constraint that makes it weaker.
Text equivalent: derive requirements, choose a default, qualify it against constraints, add operational and failure behaviour, then explain the trade-off.
High-value traps
- Tags do not inherit without policy.
- NotActions is not an explicit deny.
- Root-scope assignments can create exception debt.
Scenario rehearsal
An organisation asks for the capability described by the first matrix row, but also adds a strict recovery target, private connectivity, and a small operations team. Write a recommendation that identifies the core service, the supporting continuity and network controls, and the operating trade-off. Then reject the nearest service alternative using one explicit requirement. If your answer lists products without a traffic, data, identity, or recovery flow, it is incomplete.
Final-minute checklist
- I can distinguish every service in the matrix by requirement, not logo or name.
- I know which controls operate at identity, management, data, and network planes.
- I check regional/SKU support and current limits when a scenario depends on them.
- I include monitoring, health, capacity, recovery, and ownership in the recommendation.
- I can explain why the strongest distractor fails.
