A clear understanding of some basic concepts can make a huge difference in the way you tackle any system design problem.
After analyzing 30 key system design concepts, I’ve put together this one-page cheat sheet to help you:
1. Scale like a pro – Auto-scaling, horizontal scaling, database sharding, and CDN strategies.
2. Manage data efficiently – Data partitioning, NoSQL, SQL transactions, and indexing best practices.
3. Ensure reliability & fault tolerance – Load balancing, redundancy, heartbeat mechanisms, and event-driven architecture.
4. Master caching strategies – Read-through vs. write-through caching, Denormalise Databases, and Distributed Caching.
5. Design flexible architectures – Microservices, async tasks, and avoiding over-engineering.
6. Define problems before jumping into solutions – System constraints, trade-offs, WebSockets, and security.
This is the ultimate cheat sheet I wish I had before my system design interviews.
