> Kubernetes is up to 80% cheaper compared to PaaS like Heroku and you can choose between different cloud providers (no lock-in).

I'm not a fan of these business case buzzword sentences. There is lock-in, although less, and "up to" is meaningless. It could be 81% cheaper, or it could be more expensive.

"up to 80%". isn't it to be read as "from the same price to a 80% discount" ?

Which is meaningless, like a $20,000 - $100,000 salary range.

Pretty sure he is disputing that it could be 81% cheaper that the original comment said. "Up to 80% cheaper" means 80% or less, not 80% or more.

> It could be 81% cheaper

I think "up to 80% cheaper" implies "No more than 80% cheaper".

Yes I know - I'm saying it could be even cheaper than that, or it could get more expensive to move to Kubernetes. A percentage like this isn't useful.
