I use Cloud Run for all my server rendered web apps and I _love_ it. That’s where the pricing model makes sense since as soon as the request is served I stop paying. The actual cash price is less than what I was paying to run on GKE and the total cost of ownership is far lower.

Web sockets are a handy thing to have access to but the app described is a pretty pathological case for the Cloud Run pricing model. I think people knocking the article on pricing alone are missing the point.
