An interactive simulator demonstrates how different load balancing algorithms distribute traffic across servers. It covers Round Robin, Least Connections, IP Hash, and Least Response Time strategies, explaining when to use each approach. The tool illustrates server failure handling, Layer 4 vs Layer 7 differences, and includes real-world examples from NGINX, AWS ELB, Kubernetes, and Cloudflare. Best practices include using weighted algorithms for varying server capacities, implementing health checks, and choosing appropriate layers for specific routing needs.

Looks cool, but it’d be better if you could demonstrate what happens when one of the servers fail

Nice blog on load balancing, and a great UI explanation of each method showing how requests are sent to different servers.

What if a request has already passed the load balancer and server failed before processing request
wouldn’t it will be counted as failed request ?

This is an amazing little simulator, super clear and demonstrates to people exactly what’s going on. Definitely going to share this with my team
