I agree about making an informed choice. I disagree with: > Because by choosing RoR you are making an assertion up front: our startup will never scale beyond X users (because you're never going to get buy-in for a rewrite). How can this be true when we know that Shopify, Gitlab, Github and all others are using RoR. Here is a more concrete scale[1]: > We served 75.98 Million requests per minute to our commerce platform at peak. That’s 1.27 Million requests per second! Is that a bit enough limit for you? Here is more: > We achieved 99.999+% uptime while averaging 3 Terabytes per minute of egress traffic across our infrastructure [2] [1] https://twitter.com/shopifyeng/status/1597983926126977024 https://twitter.com/shopifyeng/status/1597983926126977024 [2] https://twitter.com/shopifyeng/status/1597983918900510720 https://twitter.com/shopifyeng/status/1597983918900510720
