THE EVOLUTION OF SOUNDCLOUD'S ARCHITECTURE: PART 1

Summary from the TLDR Web Dev newsletter

SoundCloud kept its initial technology stack simple. As the platform grew, it made strategic choices, like adding HAProxy and RabbitMQ, to address performance bottlenecks caused by long-running requests and high traffic. To further optimize performance and support its growth, SoundCloud eventually decoupled its architecture, introduced caching and new data stores, and transitioned towards a microservices model.
