AWS and older hardware is no different. Set it once and it keeps running for many years.

I've came across old AWS account (startup have been using AWS for the longest). All the network traffic or VPN goes through a single instance with 3 years of uptime.

AWS EC2 instances or their host machines can fail at any time and it’s out of your hands.

True fact! I recently had EC2 migrate my VM when the physical server it was on reached EOL. If they had fired my VM up again, I wouldn't have even noticed. They didn't. Fortunately it had an EBS volume and I was able to manually restart it without data loss.
