Load balancers are critical for managing traffic in distributed systems, ensuring scalability, fault tolerance, and optimal performance. In this video, we explore why load balancers are essential, their role in horizontal scaling, and how they perform health checks to maintain system reliability. We’ll break down key static and dynamic load balancing algorithms, including Round Robin, Weighted Round Robin, Least Connections, IP Hashing, and URL Hashing. Learn how these strategies distribute traffic and keep modern systems like Netflix and Amazon running smoothly.
