AWS Summit is approaching. I usually find other teams, even nominal competitors, or hulking behemoths of industry, to be quite proud of what they've built, and generous with their battle tested knowledge. All you have to do is reach out and ask ;)
Be careful with things like this - it is ultimately an AWS marketing channel, so they’re not going to bring on people who say “we tried running everything on Lambda and it turned out to be a deployment nightmare”. The very best way to do this is find a tech meet-up around the sort of thing you do, and then go for the after event drinks. Get to know people, chat with them, and find out all the many ways architectures can shoot you in the foot.
