  title: F5 Load Balancer F5 BIG-IP Application Services 3 Extension (AS3) Config Data Groups API
  description: The Application Services 3 Extension (AS3) provides a declarative API for managing application-specific configurations on BIG-IP systems. AS3 uses JSON declarations to describe the desired state of Layer 4-7 application services, enabling infrastructure-as-code workflows for load balancing, SSL offloading, and traffic management. Rather than issuing imperative commands, users submit a complete declaration and AS3 configures the BIG-IP to match the declared state.
