Load Balancer – Your Cloud Traffic Cop 🚦
A Load Balancer spreads traffic across multiple instances so no single instance gets overwhelmed:
- Types: ALB (Application Load Balancer), NLB (Network Load Balancer)
- Ensures high availability – your app doesn’t crash when traffic surges
- Think of it as a traffic cop directing cars so no road jams happen 🚗🚙🚗
Quick Analogy
| Component | Analogy |
|---|---|
| Load Balancer | Traffic cop 🚦 |
| Multiple Instances | Multiple lanes on a highway 🛣️ |
| Users | Cars trying to reach destination 🚗 |
Why Noobs Should Care
- Your apps stay fast and available even if traffic spikes
- AWS automatically handles scaling and distribution – you chill 😎
- Great for websites, APIs, or anything that might go viral 📈
Pro Tip
- Start simple: one instance + ALB (optional)
- Experiment with Auto Scaling policies once comfortable
- Monitor CloudWatch metrics to
