Скачать или смотреть Vertical vs Horizontal Scaling 🔥 | System Design Explained Simply (with Real Examples)

Scaling is one of the most important — and misunderstood — parts of System Design.

In this video, we break down Vertical Scaling vs Horizontal Scaling in the simplest way possible, with visual comparisons and real-world examples inspired by Alex Xu’s System Design Interview book.

🔍 What you’ll learn:
✅ What is Vertical Scaling (Scale-Up) — when and why it’s used
✅ What is Horizontal Scaling (Scale-Out) — benefits and trade-offs
✅ The impact on fault tolerance, scalability, and cost efficiency
✅ Real examples from large-scale systems like Amazon, Netflix, and YouTube
✅ How to choose the right scaling strategy for your project

💡 Quick takeaway:
Vertical scaling gives more power to a single machine 💻,
while horizontal scaling adds more machines to share the load ☁️.

By the end, you’ll clearly understand when to scale up vs scale out, and why most real-world architectures use a hybrid approach for maximum efficiency.
