Abstract: To address the issues of abundant and frequently changing IT resources, complex IT architecture relationships and the lack of a unified IT service resource platform for collaboration among various technical departments, this paper analyzed internal business data operation status and combined the requirements of the bank’s secondary office and three centers. A model was proposed, introducing object-oriented design concepts to manage all IT service resources. By combining basic resources with models such as environment, application, and system management, various resource relationships were decoupled. This decoupling avoided the differences in actions across different systems, applications, and environments during DevOps automation construction. In conjunction with B/S architecture and OrientDB graph database technology, a resource management platform suitable for the financial industry was designed to effectively manage IT service resources and provide capabilities such as resource relationship topology visualization, data analysis visualization, and open external interfaces. This platform can provide scientific decision support for resource change impact analysis and resource fault analysis.
