In the paper, the issues of modeling information technology for remote monitoring of technological processes and objects with the ability to control the state of monitoring objects are considered. The main objectives and constraints in the form of ISO/IEC/IIC standards and recommendations have been defined. According to the structural analysis and design methodology, a set of input and output parameters, mechanisms, and constraints affecting operations and data flows have been defined. A conceptual model of information technology for monitoring systems has been built and decomposed in the IDEF0 notation, the possibility of its implementation is shown using the example of a data acquisition unit in the form of an intelligent router that provides collection, processing, temporary storage of data and communication with a data processing server.

The current state of using CI/CD in commercial and open-source projects is analyzed. CI/CD pipelines are shown to be essential to the modern software development process, where they are used to configure workflows. Centralized and distributed approaches to building a software source code version control system are analyzed. For the web-oriented SCADA project, the choice and use of the version control system are justified. We provide concrete examples of using CI/CD that will allow ordinary developers, not DevOps specialists, to take the first steps to configure workflows for their projects and provide basic steps for configuring task execution using the example of the build and test phase of the source code of a real project that uses several programming languages. Проаналізовано поточний стан використання CI/CD у комерційних та opensource проектах.

Remote monitoring of objects or technological processes is used in many industries and service-oriented companies to obtain up-to-date information about the state of things or technical processes. The article is devoted to developing, analyzing, and implementing information technology (IT) for remote monitoring. The high-level design of IT and system for its implementation is based on the IDEF0 Functional Modeling methodology that describes the system hierarchy and establishes horizontal links between various activities. The achieved results confirm the possibility of implementing the proposed technology. The results will be of interest to technical specialists involved in the development of relevant applications but also to business analysts and managers for a better understanding of modern applied information technologies.
