This project stood up a new generation of AKS clusters specifically so we could decommission an older, duplicate set of infrastructure that was quietly costing money every month.</p> <p>The approach was straightforward: build the new clusters alongside the old ones, migrate workloads over, validate, and then tear down the legacy infrastructure. Running both environments in parallel for a short overlap period had a real (if temporary) cost - a few thousand dollars over a couple of months - but it bought us a safe cutover with a rollback path, which was worth it compared to the ongoing cost of carrying duplicate infrastructure indefinitely.</p>
