Performance evaluation of cloud computing accounting for expenses on information security
А. Д. Хомоненко, Sergey I. Gindin · 2016
An approach to the performance evaluation of cloud computing accounting for the expenses on information security is proposed. For this purpose the model of multi-channel non-Markov queueing system with a “warm-up” is used. When applied to information security at cloud computing warm-up can be understood as: user/terminal authentication, network encryption, caching database queries, on-demand resource allocation, etc. The study demonstrates the influence of the “warm-up” process on the cloud computing performance and shows the need to collect data and examine “warm-up” patterns to assure that the system capabilities are appropriate for significantly different levels and patterns of demand. Obtained results of numerical experiments show the influence patterns which the “warm-up” process has on the system performance.
