Annotation: International organizations deploy distributed IT infrastructure in different countries, taking into account the requirements of national legislation, supranational regulators, and industry standards. Failure to comply with the regulations of any jurisdiction can lead to serious legal, financial, and reputational consequences, making it crucial to monitor the compliance of IT infrastructure with international and national regulations, as well as to control its reliability, availability, and information security. In such conditions, traditional engineering approaches to infrastructure design are insufficient without integrating multi-criteria selection models, risk-oriented management, and compliance management. The purpose of this article is to develop, based on the application of multi-criteria selection models, risk-oriented management, and compliance management, libraries of standard architectural solutions, as well as a formalized model and algorithm for selecting the optimal scenario for building an IT infrastructure architecture for foreign offices of an international company in multiple jurisdictions with heterogeneous legal regimes, various network restrictions, and high uncertainty in the regulatory and technological environment. The practical significance of the proposed model and algorithm lies in the fact that 2 they: provide arguments and reduce the decision-making time for IT managers and compliance officers of international organizations; document and provide a formal justification for the choice of IT infrastructure architecture for each jurisdiction of the countries of presence during audits and regulatory inspections; and maintain the architecture of the distributed IT infrastructure in an up-to-date state, allowing for the preevaluation of the consequences of possible changes in the regulation of data flows and localization requirements. The results obtained can serve as a conceptual and methodological basis for applied decision support systems in the field of building, developing, and managing international IT infrastructure.
