This is really thorough and truly mirrors the way system at scale are architected in companies. The best set of videos on system design out there. Please continue making more of these :). Mom's favorite flower part was really funny. I can totally relate to this. Selling your platforms to different teams in your company is already super hard, never complicate it further by telling them to add a service client :D

4:00 why a rate limiter needs to be designed as a distributed system and not just for a single host 11:00 algorithm for deciding wether to accept or reject req, token bucket algorithm keeps a bucket of tokens for each unique client, and has a re-fill rate. When client makes a req we check if it has tokens remaining, if not reject 14:50 classes and interfaces oop 17:00 rate limiter across different hosts in a cluster 18:30 how token buckets communicate each just says how much they’ve used so far and the others can sum and make decision

I wanted to propose a slight change to refill method see if you accept it. 1. private void refill ( int tokens) 2. replace line #3 in refill method with -> currentBucketSize = Math.min(currentBucketSize + tokenToAdd, maxBucketSize + tokens); Also in the allowRequest method first line will change from refill() to refill(tokens);
