This can lead to performance degradation compared to the execution of services in isolation. This work proposes a Confirmatory Factor Analysis (CFA)-based model to estimate performance interference across containers, caused by the use of CPU, memory and IO across a number of co-hosted applications. The approach provides resource characterization through human comprehensible indices expressed as time series, so the interference in the entire execution lifetime of a service can be analyzed. Our experiments, based on the combination of real services with different profiles executed in Docker containers, suggest that our model can accurately predict the overall execution time, for different service combinations. The approach can be used by a service designer to identify phases, during the execution life-cycle of a service, that are likely to lead to a greater degree of interference, and to ensure that only complementary services are hosted on the same physical machine. Interference-awareness of this kind will enable more intelligent resource management and scheduling for cloud systems, and may be used to dynamically modify scheduling decisions. info:eu-repo/grantAgreement/ES/DGA-FSE/T35-17D info:eu-repo/grantAgreement/ES/MINECO/PGC2018-099815-B-100 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.4 2023 COMPUTER SCIENCE, INFORMATION SYSTEMS 87 / 250 = 0.348 2023 Q2 T2 TELECOMMUNICATIONS 47 / 119 = 0.395 2023 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 122 / 353 = 0.346 2023 Q2 T2 0.96 2023 Engineering (miscellaneous) 2023 Q1 Materials Science (miscellaneous) 2023 Q1 Computer Science (miscellaneous) 2023 Q1 9.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Arronategui, Unai Universidad de Zaragoza (orcid)0000-0003-4457-3938 Rana, Omer Bañares, José Ángel Universidad de Zaragoza (orcid)0000-0002-4198-8241 Tolosana-Calasanz, Rafael Universidad de Zaragoza (orcid)0000-0003-3057-6273 5007 035 Universidad de Zaragoza Dpto.
