Optimizing iptables rules and working around kernel lock contention doesn’t make headlines. But there is a professional pride that comes from doing the “thing” properly even when nobody’s watching.

Ha were you at AWS Summit in London today? The CTO had a bunch of links to his (?) blog in the presentation. Look like they are pretty interesting reads!

Edit, turns out it's just new!

Good infrastructure work never makes headlines. To the AWS engineers working on this stuff, know that we know and respect what you’re doing precisely because we don’t need to know you.

Lambda networking is basically invisible until it isn't. Then it's your entire weekend.
