BriefCaseStudy
I'm on my way to become a senior dev, and system design never made sense to me on paper. I knew the concepts but I was struggling putting them together. It only started making sense to me once I started reading case studies of outages. So I've been turning them into 5 minute cases you can play through, as if you were the one fixing the outage. Then you see what the real team did, and roughly how your version of the choices would've gone. The hardest part in this project for me has been scoring. Rating your choices against what the company did feels wrong as there are many correct choices, and sometimes the company got it wrong too, so answers are pretty much rated against what was known at that minute. The first one is Supabase's February outage, where a monitoring deploy cut off a whole AWS region: https://briefcasestudy.com/system-design/c/0 I'd love to hear any feedback, or if you learned anything from this case :D
