Ever heard of “Single Point of Failure (SPOF)” in System Design Interviews?
If not — this might be the reason you fail your next tech interview. 😬

In this reel, I break down:
✅ What is a Single Point of Failure (SPOF)
✅ Why it’s dangerous in large-scale systems like Netflix, YouTube, or Instagram
✅ How to avoid it in your designs — by using replication, load balancing, and redundancy
✅ Real-world examples from distributed systems

Whether you’re preparing for FAANG interviews or just starting to learn System Design, understanding SPOF is non-negotiable. Interviewers often test this concept when they ask questions like:

“How would you ensure high availability?”

“What if this server goes down?”

“How does your system recover from failure?”

🎯 Here’s why this matters:
Even a perfect design can collapse if you don’t eliminate SPOFs. A single database, a single server, or even a single network link can bring down your whole product — leading to downtime, data loss, or user frustration.

In this video, you’ll learn how to design fault-tolerant, highly available systems that scale and survive real-world failures.

👩‍💻 Perfect for:

Aspiring Software Engineers, Backend Developers, and System Design beginners

People preparing for FAANG, startups, or top tech companies

Anyone building real-world systems and wants to think like a senior engineer

💡 What You’ll Learn:

The core idea behind redundancy and replication

How to use Load Balancers to distribute traffic

Why active-active and active-passive setups matter

How big companies like Google, Netflix, and Amazon design for zero downtime

🔥 Pro Tip:
Always ask yourself — “If this component fails, does my entire system go down?”
If yes — that’s your SPOF. Fix it. That’s how you stand out in interviews.
