Abstract: Techniques for predictive autoscaling and resource optimization of software deployments. In an implementation, users declare performance objectives, and machine learning of application behavior and load profile is to used to determine minimum cost resourcing to meet the declared performance objectives. In an embodiment, convergent deployments are monitored and related feedback is provided to improve forecasting, behavior modeling, and resource estimation over time.

Abstract: A portable, motorized chain driver for lifting and lowering loads by attaching the chain driver to a manual chain hoist for driving the chain. The chain driver comprises a chain and rotor housing attached to a compact electrical or gas driver unit with an angled head, a gear reduction and a handle with direction and speed controls. The chain and rotor housing comprises two halves which include integral chain guides, a central rotor and clutch area and a drive source mount. The chain driver is particularly useful for driving manual chain driven hoists and garage doors.
