Stateless vs Stateful in Horizontal Scaling | System Design Interview Guide

Описание: In this video, I explain why stateless architecture is critical for horizontal scaling and how it helps build scalable, reliable, and distributed systems.

If you're preparing for System Design interviews or working as a backend engineer, understanding this concept is extremely important.

In this video, you’ll learn:
1. What horizontal scaling means
2. Difference between stateful and stateless architecture
3. Why stateful systems create scaling bottlenecks
4. How stateless services improve load balancing
5. Real-world system design relevance
6. Interview-focused explanation

Stateless architecture allows any server to handle any request, which makes scaling out much easier and more efficient.

This concept is heavily used in large-scale systems like:
1. Microservices architectures
2. Cloud-native applications
3. Distributed backend systems

Ideal for:
1. SDE2 / Senior Engineer interview preparation
2. Backend developers
3. Engineers learning System Design
4. Anyone building scalable systems
