The paper proposes a resource framework
COROB
for overload handling in component application hosting center through dynamic resource borrowing among hosted applications. The main idea is to utilize the fine-grained idle server resource of other applications to partake of surging workload, while keeping the resource borrowing under control for not violating the SLA of the donor application. The contribution of the paper is two-fold: (1) a queuing analysis-based resource borrowing algorithm is proposed for overloaded applications to acquire as exact amount of resource as possible; (2) an adaptive threshold-driven algorithm is presented to drive the overload handling with threshold values adaptively tuned according to changing workload. Empirical data is presented to demonstrate the efficacy of COROB for overload handling and response time guarantee in a prototype service hosting cluster environment.
