Original: What Is Load Balancing? A Beginner's Guide to Faster and More Reliable Applications
Short summary
A beginner-friendly introduction to load balancing using a supermarket checkout analogy, explaining how traffic is distributed across multiple servers to prevent overload. Covers horizontal vs vertical scaling, request routing flow, and common algorithms like round-robin and least-connections. The article is mostly conceptual with ASCII diagrams and lacks depth for practitioners.
- •Load balancers distribute requests across servers to prevent single-server overload
- •Common algorithms include round-robin and least-connections routing
- •Article is entry-level with analogies but thin on implementation details
