It works fine, performance is good enough for most.

Amazon just announced their own custom-designed AArch64 server 
core for AWS:

I mentioned the Cloudflare server benchmarks against Intel 
earlier in this thread, comparable performance with half the 
electric power dissipation:

All that said, I don't think cloud will matter that much, as 
mobile p2p is poised to replace a lot of it.
