Sometimes it can be hard to give up sysadmin work because people consider it to be a core competency and to let that go feels like a loss. Kubernetes hits the sweet spot where you get to use a tool to manage sysadmin work that is at least as much work as hiring a sysadmin.
I completely agree but I’m not sure “cost-sensitive” is an adequate term because it’s like a cost on hosting (or an app you’ll use for years) triggers extremely high awareness by people who are extremely blasé about hemorrhaging staff time on support and slipped deadlines.
