Hints for Distributed Systems Design 🤟
The blog post by Murat Demirbas provides heuristic principles for designing robust and efficient distributed systems. Inspired by Butler Lampson's work, the post categorizes these principles into functionality, performance, and fault-tolerance. Key takeaways include the importance of abstraction for simplifying complex systems, minimizing coordination to improve efficiency, and ingraining fault-tolerance from the design phase. The author also emphasizes leveraging time for performance gains and the need for observability tools. A bonus hint suggests rethinking system design for the cloud era, moving away from traditional physical box models to a more flexible, cloud-based approach.
