Perfenforce Demonstration: Data Analytics With Performance Guarantees

We demonstrate PerfEnforce, a dynamic scaling engine for analytics services. PerfEnforce automatically scales a cluster of virtual machines in order to minimize costs while probabilistically meeting the query runtime guarantees offered by a performance oriented service level agreement (SLA). The demonstration will show three families of dynamic scaling algorithms feedback control, reinforcement learning, and online machine learning and will enable attendees to change tuning parameters, performance thresholds, and workloads to compare and contrast the algorithms in different settings.
