> Cloud costs are higher than DC costs Those aren’t the only options. VPS are a thing, cost less and are pretty easy to operate (even easier than cloud, I’d argue). You can, of course, use cloud services for some stuff (databases? S3?) that are high maintenance, but some things (like the Cognito example from the OP article) just don’t make sense from the point of reducing costs – you trade some complexity for more complexity with a vendor lock-in and some additional costs on top.
