Embodiments dynamically measure latency for a plurality of functions with a plurality of corresponding frequency levels within a serverless computing cluster; measure a transition latency from an idle state to an active state for the plurality of functions; determine whether a target response time to perform a service level objective (SLO) within the serverless computing cluster is going to be missed; dynamically reallocate at least one core and changing a frequency level across the plurality of functions by scaling down in response to a determination that the target response time to perform the SLO within the serverless computing cluster is going to be met; and dynamically reallocate the at least one core and changing the frequency level across the plurality of functions by scaling up in response to a determination that the target response time to perform the SLO within the serverless computing cluster is going to be missed.
