Exactly. SRE is about monitoring and troubleshooting at scale.
Google runs on a microservices architecture. It's done that since before that was cool. You have to do a lot to make a microservices architecture work. Google did not advertise a lot of that. Today we have things like Data Dog that give you some of the basics. But for a long time, people who left Google faced a world of pain because of how far behind the rest of the world was.
As I see it, the issue isn’t requiring static compiling to scale. It’s requiring it to make troubleshooting or measuring performance at scale easier. Not required, per se, but very helpful.
