The article presents an analysis of the theoretical foundations of cloud migration – the process of transitioning from traditional on-premises IT infrastructure to cloud-based solutions. It emphasizes that the current conditions of business operations and the public sector are marked by increasing demands for scalability, flexibility, and information security, which are often unattainable using outdated local systems. However, despite the numerous advantages of cloud technologies, the migration process is accompanied by a range of challenges related to data protection, compatibility, legal compliance, and cybersecurity risks. Based on the analysis of recent studies, including both international and Ukrainian scientific publications, the paper identifies three key aspects that must be considered during cloud transformation: (1) the shortcomings of traditional on-premises IT infrastructure, including high maintenance costs, limited scalability, technical complexity of support, and low resilience to failures; (2) the advantages of cloud-based solutions, such as flexible scalability, cost-effectiveness, the availability of service models like IaaS, PaaS, and SaaS, automated management, and compliance with international security standards; and (3) the challenges of securely transferring services and data, covering issues such as encryption, access control, system compatibility, and adherence to legal regulations. The article also focuses on modern practices for securing information in cloud environments, including penetration testing, microsegmentation, the use of multi-factor authentication, and risk management models. A systematic approach to planning and implementing cloud migration is proposed, taking into account the specifics of business processes, technical limitations, regulatory frameworks, and information security threats. The results of the study can serve as a foundation for developing digital transformation strategies across various industries, as well as an analytical basis for further scientific and applied developments in the field of cloud security and IT infrastructure optimization.
