Substantiation of the declarative approach in the development and management of information systems using cloud technologies

In today's world of rapid technological development and the growing importance of information systems for large organizations, including the Armed Forces of Ukraine, the need to optimize their development and management is becoming urgent. In the Armed Forces of Ukraine, the principle of hierarchy prevails in the construction of information and communication systems, which imposes restrictions on the process of implementing new flexible solutions. The process of developing and managing information systems is mostly based on the imperative approach. At the same time, the use of the declarative approach in these systems opens up wide opportunities to ensure their efficiency, flexibility and simplicity in development and management. The article discusses the possibility of using the principles of the declarative approach to optimize the development and management of information systems using cloud technologies, and also the advantages and examples of its application. The research is concerned with the need to optimize the process of developing and managing information systems using cloud technologies in the context of the rapid pace of technology development and the growing needs of the Armed Forces of Ukraine to use these systems to increase information awareness and accelerate decision-making by commanders during combat operations. The purpose of the study is to analyze the principles of the declarative approach and determine its capabilities for optimizing the development and management of information systems using cloud technologies. To achieve this goal, the author uses methods of analyzing the current state and trends in the development of cloud technologies, as well as analyzes examples of the declarative approach in various IT projects. The analysis shows the importance of the declarative approach to improve the efficiency of development and management of information systems using cloud technologies. The results of the study may be useful for departments considering implementing the declarative approach in their projects. The declarative approach can be applied in the latest developments of information systems to increase the level of automation and optimize the infrastructure management processes of the Armed Forces of Ukraine.
