A method dynamically responds to a change in a workload managed by Availability Management Framework (AMF), where the workload is represented by a set of service instances (Sis) protected by a service group (SG) in a cluster. When receiving a notification of the workload change indicating an impacted SI in the set of Sis, the method applies at least one strategy from a collection of SG-level strategies and cluster-level strategies to adjust an amount of resources available to at least the impacted SI. Each SG-level strategy changes one or more configuration attributes within the SG according to a redundancy model used by the SG, and each cluster-level strategy changes one or more configuration attributes within the cluster according to one or more redundancy models used by SGs within the cluster. The method causes the AMF to apply a configuration change to respond to the workload change.
