The present study is devoted to the analysis of architectural approaches to scaling financial systems based on SAP HANA platform, which is an urgent task in the context of growing volumes of transactional data and increasing complexity of computational processes. The features of SAP HANA architecture based on in-memory technology, which provides high performance and low latency in data processing, are considered. Special attention is paid to the comparison of horizontal and vertical scaling, their advantages and disadvantages in the context of financial systems. A combined approach that combines both methods to achieve an optimal balance of performance and fault tolerance is presented. The paper concludes with recommendations for selecting the appropriate architectural solution depending on the needs and characteristics of the organization, and suggests directions for further research, including integration with cloud technologies.
