🚀 CDN vs Load Balancer

Both improve performance and reliability. 
But they solve different problems.

1️⃣ CDN (Content Delivery Network) 🌍

Distributes static content across global servers.

➤ How: Caches images, CSS, JS near users 
➤ User connects to nearest CDN server 
➤ Wins: Faster load times, reduced server load 
➤ Risk: Mostly for static content 

Best for:
Images, videos, static assets

Flow:
User → Nearest CDN → Cached content delivered


2️⃣ Load Balancer ⚖️

Distributes traffic across multiple servers.

➤ How: Routes requests to healthy backend servers 
➤ Wins: High availability, prevents overload 
➤ Risk: Does not cache content 

Best for:
Handling high traffic APIs

Flow:
User → Load Balancer → Server A / Server B / Server C


💡 Key Difference

CDN → Speeds up content delivery 
Load Balancer → Distributes traffic 

CDN = Performance optimization 
Load Balancer = Traffic management
