This is actually not at all unusual, and even when it's not already the case, most well-architected applications serving hundreds of concurrent users can already scale to 1ks or 10ks without changing anything.
I think this is where your disconnect is. In 2019, 10ks of concurrent users is not special. It's ordinary. Even 100ks or 1Ms are not that unusual.
I am not a fan of cloud services or most of the new hotnesses in vogue today, but this is something that they've enabled even most new grads with an iota of training to do.
Looking from the outside in, the problem (and arms race) involved in determining whether one video is actually a 'like'/edited version of another infringing video seems much more interesting.

So which services have 1M concurrent users, outside of the top 10? At 100M daily users a service would get 1.1k users per sec (on average). And those have quite large deployment and plenty of engineers.
- Amezarak 7y agoA lot of services peak in the millions. I don't know what you consider the top ten, but a lot of chat apps - Discord, Skype, Whatsapp (even prior to Facebook acquisition, and which famously had what, 50 employees?), a lot of games, mobile and desktop, top apps in the app store, top couple hundred websites or so. If we just think about TPS, bajillions of applications you've never heard of are dealing with large loads (10-100k TPS) in every economic sector you can think of.
- doh 7y agoWhatsApp stored no data and ran everything as through service, that's why they did it with so few engineers. Almost no games ever reach scale close to what you just wrote. The few that do are known with large technical teams. Same goes to everything else. The reason why you can name them almost all is because it's so rare. You are grossly overblowing the numbers. Only a very few services ever get to these numbers and once they do, they talk about the challenges of scale constantly [0] [1] [2] [0] https://blog.discordapp.com/using-rust-to-scale-elixir-for-11-million-concurrent-users-c6f19fc029d3 https://blog.discordapp.com/using-rust-to-scale-elixir-for-1...
