Models of the information structure of multicloud computer systems with data replication

In the article, a conceptual model of the information structure of a multicloud system in the form of an IDEF0 diagram is proposed. Its decomposition for a native multi-cloud of the DBaaS type with identifications of the input and output parameters, mechanisms, and restrictions is developed. Based on these information models, a mathematical model of a generalized type of multi-cloud with data replication has been developed, which takes into account the geo-location of both the resources of cloud service providers and clusters of end users.
