摘要：Cloud elasticity allows dynamic resource provisioning in concert with actual application demands. Self Tuning fuzzy control has been applied with success to resource allocation. However, cloud dynamics make the design of the accurate and stable resource controller challenging, especially when client request increased gradually. To address these challenges, we introduced novel fuzzy controller (NFC) approach with neural concept and used scheduling algorithm. It supports adaptive multi-objective and service differentiation. Experimental results on representative server workloads show that NFC approach outperforms popular controllers such as Kalman filter, ARMA and, Adaptive PI in the control of CPU, memory, and disk bandwidth resources under both static and dynamic workloads
