Professional practice
Case studies
The responsibility, judgement and outcomes behind my work in cloud and infrastructure operations. Each study explains the decisions I made, what changed and what another IT professional can apply.
Two studies. From recognising capacity risk to designing change that a team can safely reverse and continue.
Case study 01 · Operational resilience
Establishing operational control across a global Azure SQL estate.

- Practice
- Capacity risk, evidence-led reporting and ACOI
