This paper proposes to employ linear programming algorithms for global resource scheduling to reduce the extra cost, including power consumption as well as operation expenditures, for remote resource access in a cloud-based resource pool. Unlike previous static work in this field, the proposed scheduler adapts the problem-modeling granularity and resolution algorithm to the changing demands of an integral procedure comprising various stages including the initial construction and subsequent operation/extension of a cloud-based resource infrastructure. In particular, the proposed scheduling strategies take into account resource configuration, service deployment and real-time load, among other factors, to strike a trade-off among the scheduling performance (i.e., cost reduced), response time, and computation cost, from a service or infrastructure operator's point of view.
