Agreed, sure scaling is one factor, but I don't think this person has ever really dived into why containers are slick. Why you aren't tracking down what dependency hell caused your app to crash. Conflicting cuda versions. Two apps using the same port. Trying to decipher a language you've never used before
Whenever I hear "containers are too complex" or "I don't like containers" I read it as "I don't understand containers". There are some real flaws to them, but no self respecting ops engineer would ever say "containers have no value beyond scaling"
