Titre : Improving resource elasticity in cloud computing thanks to model-free control Auteurs : Cédric Join, Michel Fliess, Maria Bekcheva, Alireza Moradi, Hugues Mounier, Revue : Control Numéro : Issue 1 Volume : 2 Date : 2018/10/1 DOI : 10.21494/ISTE.OP.2018.0296 ISSN : 2631-4924 Résumé : In cloud computing management, the dynamic adaptation of computing resource allocations under timevarying workload is an active domain of investigation. Several control strategies were already proposed. Here the modelfree control setting and the corresponding “intelligent” controllers, which are most successful in many concrete engineering situations, are employed for the “horizontal elasticity.” When compared to the commercial “Auto-Scaling” algorithms, our easily implementable approach, behaves better even with sharp workload fluctuations. This is confirmed by experiments on Amazon Web Services (AWS). Éditeur : ISTE OpenScience
