DEVELOPMENT OF A CONCEPTUAL MODEL FOR ENSURING FAULT TOLERANCE OF SOFTWARE SYSTEMS
Digital transformation is a comprehensive process of integrating information technology into all areas of human activity. Almost all aspects of our lives, from personal communications to global economic processes, are increasingly integrated with digital technologies. Banking, manufacturing, healthcare, education, and transportation are all increasingly using software to improve efficiency, optimize processes, and provide new services. Modern applications are becoming increasingly complex, consisting of many interconnected components. This increases the likelihood of errors and failures. The relevance of research in the field of software reliability is steadily growing.This article is devoted to the study of the differences and relationships between information and software systems, as well as an in-depth analysis of the key concepts of software reliability and fault tolerance. The main approaches and strategies for ensuring fault tolerance are considered, including redundancy, backup, monitoring, duplication, load balancing, microservices, backup, prediction and detection of errors, as well as their practical application. The aim of the study is to define the principles and methods of self-healing software and to analyze the risks associated with automatic response to failures. To solve the problem of ensuring fault tolerance in dynamic and complex software systems, a conceptual model for designing reliable, self-learning and self-adaptive systems is proposed (pp.35-46).
