What a load of rubbish. What, pray tell, do you want to replace it with? Bare metal? VPS? You think that is more elastic and cost effective? If you can run stuff on Lambda or similar, fine. But that's a fundamentally platform and set of affordances and constraints, that may or may not fit... So you need to have proper SRE/DevOps engineers running your platform. How bout you "full stack script kiddies" realise that platform engineering is actually complicated and requires more that just knowing about the latest fashionable bundler!
