Abstract
The article proposes a workspace representation model for real-time systems in distributed structures using the CAP theorem. This model reflects the principles of operation of real-time systems in distributed systems, where it becomes possible to determine the size of the workspace. The workspace representation model has a feature that consists of choosing some compromise solutions between two boundaries. This allows developers to design a real-time system, taking into account the “margin of safety” (or reliability) of the operation of a distributed structure where property P will be observed (i.e., obtaining undistorted answers). The practical implementation of the object of study is based on the algorithm for creating a software environment, divided into two stages: creating and deploying a Docker image for a distributed structure. The development of a multi-stage project implementation made it possible to create research stages using real-time systems in distributed structures. The article also explores issues and problems associated with using real-time systems in distributed structures, where the properties of the CAP and PACELC theorems are mainly considered. A literature review was conducted using the CAP and PACELC theorems. A demo that violates Consistency properties (CAP or PACELC theorems) in a distributed structure is shown. Some modern solutions to the problem of using real-time systems in distributed structures have been provided.
