I wonder if an upgrade like this would be less painful if the db layer was containerized?

The migration process they described would be less painful with k8s. Especially with 2100+ nodes/VMs

Their entire setup seems somewhat suspect. I can't think of any technical justification for needing 21k instances for their type of business.
