I never understood why AWS has so much appeal when it comes to cloud infrastructure. Why not cheaper clouds? Is it about scalability, reliability, speed, modernity of equipment, customer support, UI, speed of networks?<p>Let's say the requirement is to build a platform like Twitter with 100mln daily active users. Wouldn't cloud like Hetzner with AWS/GCP/Azure failover, survive this?<p>I worked with AWS as a developer for a long time, but in pretty much ever case 10 was more than enough.<p>Would be very grateful if someone could share some insight into it!
