Storing frequently accessed data in high-speed memory (Redis, Memcached) to reduce database load and cut latency. 3. The 4-Step Interview Framework

A curated collection of PDFs, whitepapers, video links, and case studies detailing how real-world tech giants (like Netflix, Uber, and Airbnb) scale their infrastructure.

Calculate the Scale. Assume a number of Daily Active Users (DAU), read/write ratios, and estimate the required storage, bandwidth, and memory. Step 2: High-Level Architecture Design (10–15 Minutes) With the right resources at your fingertips, you

Star the repo. Download the PDF. Then close them. Open a blank whiteboard (or Excalidraw). And ask: “Under what conditions does this beautiful diagram actually fail?”
