# Service LB Policy

Service LB Policy in Google Cloud defines how internal or external load balancers distribute traffic among backend services. It allows configuration of load balancing behavior, such as session affinity, connection draining, and failover settings. This policy helps optimize performance, reliability, and traffic management for services deployed across multiple regions or instances.
