are you guys practicing much of the reactive principles when architecting system, are the feelings all positive? I have worked on a few microservice based systems and i don't think there really is a way to totally isolate any direct inter-service dependancy or am i missing a trick :)

Hey paypal devs.. I was a massive advocate of you guys up until stripe came along with a super easy payment api, since then I haven't really used anything else. Just want to know since they came on the scene what kind of board stroke improvements you have made to win back developers :) Sorry if its sensitive but will really help us busy devs read into more details later on and make the switch again :)
