To achieve the task of creating the structure of cloud services, standard methods of analysis of complex systems by the criterion of functional suitability while maintaining the basic principles of innovative entrepreneurship model are modified and supplemented. The methods are supplemented by the following elements: taking into account the hierarchy of the cloud environment, grouping of functions and structural elements of services, establishing dependencies between the functions of the service, taking into account the requirements of different technologies of building elements of cloud services, using quantitative and qualitative Quality of Service (QoS) parameters of structural elements of the service. A new model of creation of the cloud service structure based on the methods of complex systems analysis is developed. A new modular approach to building a multi-cloud service monitoring system is proposed, which will help specialists focus on abstract, non-specific cloud providers and concepts when setting up a system to control the activity of complex and heterogeneous services operating in multiple clouds. While creating the structure of the cloud service monitoring system, the proposed methods will allow simultaneously creating and controlling the Service Level Agreement (SLA) together with the system of metrics and performance indicators for cloud services.
