Yeah, not quite related to the linked slides, which are about scaling in terms of productivity, but still a great talk.

I really found that "isolation" is just a key optimization and one of the most useful properties of a system, which they call out in that talk. I wrote about it a bit more in depth here: https://www.graplsecurity.com/post/architecting-for-performa...

I've written our data processing layer and our event orchestration layer as basically an actor oriented system, with push/pull systems in a couple of key places where it makes sense. It's incredible what you can do with strong isolated infrastructure in terms of performance, security, reliability, and quality.
