Virtual Resource Overlay for Legacy Access Rule Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy resource services are constrained by outdated data models, hindering technological innovation and adoption due to the need for overhauling legacy infrastructure and uneven stakeholder support.
Innovation Solution
A thin network-based resource integration service that overlays virtual resource services on legacy services, allowing custom-defined rules and access operations through a front-end interface while maintaining backend integration with legacy systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy resource services are modified to support new innovations, then innovation capabilities are improved, but system complexity and overhaul costs increase
Solution Approach 1:
The patent introduces an intermediary layer (virtual account service, rule engine, and network-based service) that sits between the legacy resource service and the user/application. This intermediary handles innovation requirements (custom rules, virtual resources) without modifying the legacy system, thus improving adaptability while avoiding increased system complexity in the legacy infrastructure.
Solution Approach 2:
The system segments functionality by separating legacy resource management from innovation capabilities. The legacy service remains unchanged while a new virtual account service layer provides innovative features. This segmentation allows independent evolution of each layer, improving innovation capabilities without complicating the legacy system.
2Adaptability or versatility
If legacy infrastructure is overhauled to support innovations, then innovation adoption is improved, but implementation time and cost increase
Solution Approach 1:
The patent establishes a pre-built virtual account service infrastructure with rule processing capabilities and network-based service layers before innovation deployment. This preliminary infrastructure enables rapid adoption of innovations without requiring time-consuming legacy system overhauls, as the innovative features are ready to be activated through configuration rather than implementation.
3Adaptability or versatility
If custom rules and virtual resources are implemented, then resource flexibility is improved, but processing complexity increases
Solution Approach 1:
The rule engine and network-based service act as intermediaries that manage custom rules and virtual resources. These intermediaries abstract the processing complexity from the legacy system while providing flexible resource management capabilities. The complexity is contained within the intermediary layer rather than propagating through the entire system.
4Adaptability or versatility
If virtual resource services are overlaid on legacy services, then service functionality is improved, but system integration complexity increases
Solution Approach 1:
The system segments the service architecture into distinct layers: the legacy resource service layer remains unchanged while the virtual account service layer provides enhanced functionality. The network-based service acts as a bridge between these layers, managing integration complexity separately and allowing each layer to evolve independently with improved service functionality.
Data Source
AI summary
A legacy resource is virtualized as a virtualized resource defined by features and capabilities set by an individual through a front-end user interface. Access rules are set on the virtualized resource based on the features and capabilities. When an access is requested to the virtualized resource, the corresponding access rules are enforced. Assuming there is no violation in the access rules, virtualized legacy resource services are overlaid on legacy resource services to cause the legacy resource services to perform any needed access operations on the corresponding legacy resource associated with the virtualized resource without changing any workflows processed by the legacy resource services.
