5 System Design Concepts Every Developer Must Know 🏗️⚡

Why do systems break when a million users show up at once? 🤯 In this video from AI ML Python (@ai_ml_py), we break down 5 system design concepts that keep real architectures standing under pressure. Each one comes with an animated diagram, a real trade-off, and the question interviewers love to ask. ⏱️ Chapters 0:00 Why Systems Break? 0:33 Load Balancing 1:22 Caching 2:07 Replication & Sharding 2:50 CAP Theorem 3:23 Message Queues 3:57 Putting It Together 📌 What you'll learn ⚖️ Load balancing: round robin, least connections, consistent hashing ⚡ Caching: cache-aside, TTL, write-through vs write-back 🗄️ Replication & sharding: scaling reads and writes 🔀 CAP theorem: consistency vs availability when things break 📬 Message queues: retries, spikes, idempotent consumers 💬 Which concept should be our next full deep dive?
