I’m a Software Engineer at Microsoft working on high-load distributed systems. Over the years, I’ve come across many system design solutions for Stripe aka Payment Gateway and I have seen a lot of crucial details missed there. So today we will do the most complete and details system design solution for Stripe We’ll cover: How Cart Network (Visa, Mastercard) works, why do we need to use it How the integration with bank and with card network works How stripe handles 500 million payments per day (and we will design it) How to do it highly availble, with use of replication and still linearizable (strongly consistent) 00:00 Intro 00:39 Payments Domain background 01:40 How Stripe moves funds from card to merchant 05:33 How Card Network (Visa, MC) works 07:25 Define Functional Reqs 10:06 Define Non-Functional Reqs 13:02 Satisfy Functional reqs 17:02 Avoid Double Charge (CAS) 20:28 Finishing Functional reqs 22:41 Non-Functional reqs 22:58 Scale APIs and Storages 26:53 High availability, CAP 29:07 Leader-Follower vs Leader-Leader vs RAFT 30:59 continue with High Availability 33:56 Improve architecture with Kafka 36:24 Deliver webhook at least once 37:18 Kafka scaling + availability 37:43 Handling spikes 38:36 Conclusion & Feedback
