what about costs of running the application? You're not taking that into account.. I can run my elixir app far cheaper than you can a ruby app for instance. This means I can charge less than my competitors and offer more to my customers.

Sure I am, for a personal project, of which I have a couple, a $5 per month Digital Ocean droplet can run pretty much anything I will ever write.

Professionally my company uses AWS, and I will concede that you might make a small saving using a few less EC2 instances.

Edit: This is on a JVM (Tomcat) stack by the way, not Ruby.
