System Design Newsletter is the 'visual encyclopedia' of distributed systems.

It's unique for its simplified, visual-first approach—using clean diagrams to explain the difference between Kafka and RabbitMQ, or why you'd choose SQL over NoSQL. It is an essential read for anyone looking to transition from 'coder' to 'architect'.
