Managing Performance of Aging Applications Via Synchronized Replica Rejuvenation

Abstract. We investigate the problem of ensuring and maximizing performance guarantees for applications suering software aging. Our focus is the optimization of the minimum and average performance of such applications in virtualized and non-virtualized scenario. The key technique is to use a set of simultaneously active application replica and to optimize their rejuvenation schedules. We derive an analytical method for maximizing the minimum any-time performance for certain cases and propose a heuristic method for maximization of minimum and average performance for all others. To evaluate our method we perform extensive
