Mine is in the picture: 1544 days and counting!
It's an EC2 nano instance that's used only as a monitor for a few services that are running inside my VPN. It has served me well over all these years!
EDIT: before everyone starts screaming about "security":
It’s not internet facing and no port is opened, all it does is fire up a notification if/when something doesn’t reply.
Even in the unlikely scenario that someone gain access to it that means that my VPN is already compromised, and I’ve got bigger problems to worry about.
Just because it’s not public facing doesn’t mean that it’s not an issue. It might be less of an issue, but it is still a massive vulnerability.
All it takes is one misconfiguration or other vulnerable system to use this as a jumping off point to burrow into other systems. Especially if this system has elevated access to sensitive locations within your network.
