Staging is where the software is tested as a whole before the production and in many cases it's more than a few containers. I'd not pay $500 for "Up to 5 containers/env" to set up a staging environment for my app that consists of many microservices deployed on Kubernetes. My two cents; change the pricing model. It's not only expensive but also container count is not that helpful. Number of environments is a good proxy for the value I get but I don't want to be punished just because of my number of containers; cpu + memory could be more acceptable.
