Background. At the conceptual level of designing a distributed computing system, there can be proposed various schemes of client interactions with servers, in the implementation of which clients differently access one or a group of servers. An urgent problem is the organization of such interactions in cloud-based distributed computing systems (CB DCS) and the transition from a conceptual representation of the functional architecture to network applications. The object of the study is the CB DCS. The subject of the research is the synthesis technique of the functional architecture of such systems. The aim of the study is to solve the urgent task of expanding the functionality of the CB DCS, combining the properties of the actual cloud and grid systems with the properties of multi-agent systems. A feature of the proposed new functional architecture is that mobile agents performing specified functions are provided for rent to the user.
Materials and methods. The studies were performed on the basis of a networked computer interpretation of executable logical-algebraic models and apparatus of logical Petri nets.
Results. The concept of building the CB DCS based on the formalization of the transition from the cloud-based architecture of FaaS – Function-as-a-Service to the new architecture AaaS – Agent-as-a-Service is proposed. The formalization of the functional architecture of the CB DCS based on the systems of logical-algebraic operational expressions (LAOE), belonging to the class of executable models and suitable for direct software implementation in a networked computer environment, is proposed; an additional property of LAOE is the possibility of reconfiguration (modification of the operating mode) of the resulting network software. A technique for mapping a system of logical-algebraic operational expressions onto a computer network architecture that takes into account the regular nature of the model is proposed.
Conclusions. The synthesis technique of cloud systems with the new AaaS architecture, based on formalized logical-algebraic specifications, allows you to speed up the creation of software and expands the functionality of the systems in question.
