Situational management system as a multiservice technology in a cloud environment: analytic services

This article is the fourth in a series of articles devoted to the methodology of development and implementation of automated situational management systems as a public multiservice technology in a cloud environment. It is proposed to use existing IaaS (Infrastructure as a Service) and DaaS (Desktop as a Service) service models that allow implementing the required infrastructure (servers, workstations, storage, and databases) and specialized workstations with application software that implement the necessary functionality. The main approaches to the creation of a multiservice standard situational management system as a service CSaaS (Control System as a Service) are proposed. The article describes approaches to the construction and detailing of one of the main groups of CSaaS services which ensure the creation, maintenance, and use of a system of analytical services that support decision-making processes.
