Disaster recovery and data residency in Canada
summary
Overview of concrete options and tradeoffs for Canadian disaster recovery: Canada region has three AZs and supports multi‑AZ failover within a single region, while a second Calgary region Q4 2023 provides a full separate region for active‑active designs; AWS estimates a $21B regional investment over 15 years and $39B GDP impact. Recovery targets use explicit RPO/RTO numbers to pick patterns: backup/restore, pilot light, warm standby, or hot active‑active; use AWS Fault Injection Simulator to test.
