Post-Migration Optimization and the FinOps Handoff (2026): The First 30 Days After Cutover Decide Your Run-Rate

A lift-and-shift migration copies on-prem specs sized for peak plus headroom, then the migration partner rolls off and nobody owns the bill. The waste is predictable: 30–60% of cost untagged, over-provisioned EC2/RDS, idle NAT Gateways and orphaned EBS, and commitments bought on top of all of it. This is the explicit migration→FinOps handoff — owner first, visibility second, right-size before you commit — with a 30-day checklist and an optimization-backlog CSV.

A composite mid-market manufacturer exited a colo of 150 workloads and ~400 TB in 21 months across 8 waves, with 47 minutes of unplanned cutover downtime (industry median per Gartner: ~4 hours per major cutover).

Because the real cost is re-platform time (~$113k in our model), not the ~$4,400 egress line. Here is how to make an AWS workload defensibly reversible.

Multi-Cloud vs AWS-First (2026): A Buyer Decision Guide That Counts Requirements, Not Slogans

Barclays says ~86% of CIOs plan to move some workloads back; IDC says only ~8-9% fully repatriate. Both are true—the trend is per-workload placement, not multi-cloud-by-default. This guide gives you a scored matrix to decide AWS-first vs multi-cloud and prices the daily tax of "just in case" portability.
