What is system design ?
→ We make system for 100-1000 in prototype part
→ System design we need when we need to scale

Why is popular ?
Because every “tech” system is “designed”.
Companies make the product that is meant for use is “designed”.
Why System Design Matters for Developers
System design is real-world development.
Databases, APIs, cache, CDN, storage—this is what we work on in companies every day.At some point, writing code becomes secondary.
Deciding how the system works becomes the main job.
Why It’s Important for Everyone
- If you want to build systems that actually scale, system design is mandatory.
It’s not just for seniors or interviews.
System Design in the AI Era
- AI can generate code fast.
But AI cannot design scalable, fault-tolerant systems.
Real systems have:
Traffic spikes
Failures
Edge cases
That complexity needs human thinking.
What We Do in System Design
Break big problems into small ones → solve-able
Give each component a clear responsibility
Design for failure and availability
Key challenges while scaling
setting up the boundaries.
