Abstract

With its fast uptake of multi-cloud systems, the financial systems have transformed the horizon to become flexible, more scalable and cost effective. Nonetheless, the coordination and integration of information across several cloud environment comes with great challenges because of the following problems; these include data silos, poor data format and absence of interoperability. The study examines the development and execution of data federation policies of multi-cloud systems in financial systems, paying attention to the maximization of data management, integration, and accessibility between different cloud systems. We suggest an elaborate model that embraces the superior data federation tools to facilitate the smooth access to data by various cloud providers in real time e.g. data virtualization, data integration, hybrid cloud solutions etc. The framework is designed in a manner that it meets the most urgent requirements of the financial systems such as consistency of data, data security and low latency access to large data. Also the paper explores how data federation has helped to enhance the decision making ability, the efficiency in its operations, and the ability to meet regulatory requirements in financial environments. The suggested solution has been adopted and tried with a set of use cases of financial industry, which have been encouraging in terms of its performance, scalability, and data integrity. The results imply that the solution to the multi-cloud architectures in the financial system is the apprehension of the successful implementation of data federation strategies allowing the organizations to explore the full potential of cloud technologies and at the same time keep the key financial information under control.
