EVALUATION OF USER PREFERENCES WHEN CHOOSING CLOUD SOFTWARE PRODUCTS
The article analyzes the assessment of user preferences when choosing cloud software products (CSP). The peculiarity of the choice of OPP is not only the choice of an enterprise - supplier of CSP of the necessary functionality, but also the choice of enterprises-intermediaries of cloud digitalization, which include an enterprise for designing a cloud information system (CIS) based on the selected CSP and a cloud data processing center during the operation of the CIS.
