Load balancers are critical for modern web applications. They help distribute incoming traffic across multiple servers, improve performance, and ensure high availability. However, like any technology, load balancers can present challenges if not implemented correctly.

System design is a critical skill for software engineers, architects, and tech enthusiasts aiming to build scalable, reliable, and efficient systems. Whether you are preparing for interviews, planning to architect complex applications, or simply want to deepen your understanding, this structured learning path will guide you step-by-step.

System design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. It's about building software and hardware systems that are scalable, reliable, and maintainable.

Load balancing might sound technical, but at its core, it's about being smart with traffic. Whether you're building a small app or designing a large-scale system, adding a load balancer ensures your app can handle growth and users smoothly.

As user traffic to your application grows, your **load balancer** must scale and perform efficiently to maintain seamless user experiences. Poorly scaled or optimized load balancers can lead to latency, server overload, or even downtime.
