The goal of the study was to work out an approach for evaluating the reasonable system capacity under heavy workload. For that purpose, Zabbix monitoring solution is used and business metrics are applied in relation to existing system ones. A prediction data model is proposed to compute the future forecast of the user activity based on the collected historical statistics and to verify whether capacity adjustment is possible or not. The results of capacity planning are implemented at Genesys International Telecommunications Company. System analysis of the production environment indicates the possibility to downscale the capacity of certain virtual servers, which allowed savings to the annual operational costs of $3500 (50%) for each affected server.<\/jats:p>","DOI":"10.3390\/fi12050082","type":"journal-article","created":{"date-parts":[[2020,4,29]],"date-time":"2020-04-29T13:23:45Z","timestamp":1588166625000},"page":"82","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Digital Cloud Environment: Present Challenges and Future Forecast"],"prefix":"10.3390","volume":"12","author":[{"given":"Serg","family":"Mescheryakov","sequence":"first","affiliation":[{"name":"Department of Computer Science, Peter the Great St. Petersburg Polytechnic University, 195251 St. Petersburg, Russia"}]},{"given":"Dmitry","family":"Shchemelinin","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Peter the Great St. Petersburg Polytechnic University, 195251 St. Petersburg, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9412-5693","authenticated-orcid":false,"given":"Konstantin","family":"Izrailov","sequence":"additional","affiliation":[{"name":"Department of Secured Communication Systems, The Bonch-Bruevich Saint-Petersburg State University of Telecommunications, 193232 St. Petersburg, Russia"}]},{"given":"Victor","family":"Pokussov","sequence":"additional","affiliation":[{"name":"Kazakhstan Information Security Association, Almaty 050022, Kazakhstan"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,29]]},"reference":[{"key":"ref_1","unstructured":"Mescheryakov, S., and Shchemelinin, D.
