Abstract

Methods and apparatus, including computer program products, are provided for determining whether there is a benefit to implementing a dynamic cluster system rather than a static cluster system. In one aspect, there is provided a computer-implemented method. The method may include accessing, at a static cluster system, information representative of the static cluster system and accessing information representative of a dynamic cluster system. Based on the accessed information, a value may be determined, such that the value represents a benefit (e.g., an indication of usefulness or worth as well as a lack of usefulness or worth) of implementing the dynamic cluster system rather than the static cluster system. The determined value may be provided to a user interface, so that a user may decide whether to implement the dynamic cluster system rather than a static cluster system. Related apparatus, systems, methods, and articles are also described.
