i had a client who was burning… $10k? maybe $20k per month largely on nodes for EKS when they had no paying customers and ~zero load. (they had fully “production” sized clusters in all of their environments, and they had a slew of weird not-quite-prod environments.)
they also had some rabbitmq-on-k8s system going that fell over during small tests because they couldn’t get k8s to actually scale it. (which then convinced them they needed k8s, and bigger nodes)
sigh
