This leads to the enlargement of data centers, and an increase in the number of servers and virtual machines. In such systems, live migration is used to move virtual machines from one server to another, which affects the quality of service. Therefore, the problem of finding the total migration time is relevant. This article proposes analytical approach to obtaining analytical expression of the probability density of the total migration time based on the use of the apparatus of characteristic functions. The obtained expression is used to calculate characteristics of migration, taking into account the applications contributing the most randomness to the total migration time. To simplify the calculation of migration characteristics, the use of the Laguerre series can be recommended as giving more reliable results compared to Gram-Charlier series.<\/p>","DOI":"10.4018\/ijertcs.2020040104","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T12:22:20Z","timestamp":1593606140000},"page":"58-75","source":"Crossref","is-referenced-by-count":8,"title":["Analytical Approach to Estimating Total Migration Time of Virtual Machines With Various Applications"],"prefix":"10.4018","volume":"11","author":[{"given":"Andrew","family":"Toutov","sequence":"first","affiliation":[{"name":"Moscow Technical University of Communications and Informatics, Russia"}]},{"given":"Anatoly","family":"Vorozhtsov","sequence":"additional","affiliation":[{"name":"Moscow Technical University of Communications and Informatics, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2851-8472","authenticated-orcid":true,"given":"Natalia","family":"Toutova","sequence":"additional","affiliation":[{"name":"Moscow Technical University of Communications and Informatics, Russia"}]}],"member":"2432","reference":[{"key":"IJERTCS.2020040104-0","first-page":"37","author":"S.Akoush","year":"2010","journal-title":"Predicting the performance of virtual machine migration.
