I work at a pretty big company by day. Multiple billions in annual revenue - but it's NOT a tech company. It's basically retail.
Yeah we have a website (it's not e-commerce though, it's like a brochure website)
We have internal tools (stock management, a data team, etc etc)
We're fairly geographically localised... we're not international.
For a setup like that do you think Kubernetes is overkill?
