this white paper is all about how to adapt the elements in The Reactive Manifesto, https://www.reactivemanifesto.org/, to an @awscloud environment

these systems are "more flexible, loosely-coupled and scalable"

the manifesto lays out four key areas for reactive systems:

1. responsive 2. resilient 3. elastic 4. message driven

the white paper follows this structure and adds observability & tracing

I'll say this right now, tracing is absolutely critical to the success of any loosely coupled system. trying to figure out which events/messages related to which issue is a nightmare if you haven't planned ahead

that 🧠 is echoed more politely in the paper

the paper walks through example use cases (like #adtech) that you should abstract as much as possible.

you might not be serving ads but your problem set might look similar

there's also blocking & synchronicity. these are great topics to dive deeper into

the tail of the paper lines up some key @awscloud services & features with the reactive elements.

this is ok, but honestly, I would prefer a more neutral take or links out to projects that show specifics.

the middle ground doesn't hold much value here

all-in-all this is an interesting paper that highlights a great cloud-native approach to system design.

it's deep enough to give you an idea of the advantages but you'll need more if you're going to actually build a reactive system on @awscloud
