The elasticity in cloud is essential to the effective management of computational resource as it enables readjustment at runtime to meet application demands. Over the years, researchers and practitioners have proposed many auto-scaling solutions using versatile techniques ranging from simple if-then-else based rules to sophisticated optimization, control theory and machine learning based methods. However, despite an extensive range of existing elasticity research, the aim of implementing an efficient scaling technique that satisfies the actual demands is still a challenge to achieve. In this paper, we aim to address the challenge using a holistic biologically-inspired feedback switch controller. This approach utilizes multiple controllers and a switching mechanism, implemented using fuzzy system that realizes the selection of suitable controller at runtime. The fuzzy system also facilitates the design of qualitative elasticity rules. Furthermore, to improve the possibility of avoiding the oscillatory behavior (a problem commonly associated with switch methodologies), we integrate a biologically-inspired computational model of action selection. Lastly, we use some real workload patterns to evaluate the performance of the proposed approach against the state-of-the-art approaches.
