Scaling to 100k Users
This is relevant only for multimedia apps.I have fintech systems in production with 100k+ users with complex Gov app for entire country that runs on commodity hardware (majority of work done by 1 backend server , 1 database server and all reporting by 1 reporting backend server using the same db). Based on our grafana metrics it can survive x10 number of users without upgrade of any kind. It runs on linux and dot net core and Sql Server.Most of the software is not multimedia in nature and those numbers are off the charts for such systems.
