  title: F5 Load Balancer F5 BIG-IP Application Services 3 Extension (AS3) 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.

        the declaration and configures the BIG-IP to match. Use the
