Good, well-structured blueprint — the FinOps table is the most useful part, especially the contrast between monthly surprise bills and real-time tag-based cost attribution, since that is usually where the 20-35% savings you cite actually come from. One addition worth considering: the IaC disaster-recovery point assumes the state and the pipeline themselves survive the region outage, so storing Terraform state remotely with locking and keeping the pipeline definition in Git matters as much as re-provisioning the resources. Same for the canary point — automatic rollback only works if the pipeline has a clear, pre-agreed error-budget signal to trigger on, otherwise it rolls back on noise. Solid overview overall.
