Version 1.0 · Published April 2026 · Last verified April 2026
A load balancer distributes incoming network traffic across multiple backend servers to prevent any single server from becoming overwhelmed. It monitors server health, removes failed nodes from rotation, and supports algorithms like round-robin, least connections, and weighted distribution.
Why Load Balancer Matters for Your Cybersecurity Career
Load balancers play a defensive role against DDoS attacks by distributing malicious traffic across multiple endpoints. Security engineers configure load balancer health checks and TLS termination. Understanding load balancer behavior matters for incident response because attackers sometimes target session persistence mechanisms.
