Load Balancing & Auto-Scaling
Implement load balancing and auto-scaling groups to distribute traffic and dynamically adjust resources based on demand.
What is Load Balancing?
Imagine your app gets super popular! Too many users trying to access a single server can slow it down or even crash it.
Load balancing is like a traffic cop for your application. It distributes incoming network traffic across multiple servers, ensuring no single server gets overwhelmed.
How Load Balancers Work
When a user sends a request, it first hits the load balancer. The load balancer then decides which of your available servers should handle that request.
- It acts as a single point of contact.
- It checks server health to only send traffic to working servers.
- It uses different algorithms (like round-robin) to distribute requests fairly.
