> For most businesses, being able to serve 20k concurrent requests is way more than they need anyway: an internal app used by 500k This is a very simple distinction and I am not sure why is it not understood For some reason people design public apps the same as internal apps The largest companies employ circa 1 million people - that’s Walmart, Amazon, etc. most giants, like Shell, etc. companies have ~ 100k tops. That can be handled by 1 beefy server. Successful consumer facing apps are hundred millions to billion. It’s 3 orders of magnitude difference I have seen a company with 5k employees invest into mega-scalable microservice event driven architecture and I was was thinking - I hope they realise what they are doing and it’s just CV-driven development
