Load balancing is a key resilience strategy in both traditional and cloud environments. It evenly distributes network or application traffic across multiple servers to ensure no single server becomes a point of failure or overloaded, thereby improving system availability, performance, and fault tolerance.

In cloud infrastructure, load balancers may work at various OSI layers (Layer 4 or Layer 7) and are often integrated into cloud platforms as managed services (e.g., AWS Elastic Load Balancer or Azure Load Balancer). They play a critical role in mitigating risks like traffic spikes, system failure, or regional outages.

This technique is described in Domain 7: Infrastructure Security of the CCSK guidance, which highlights tools like load balancing, redundant systems, and failover mechanisms to support cloud resilience and availability.
