Centralized Request Validation Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional service-oriented systems face inefficiencies in request validation due to late detection of invalid data and tightly coupled validation schemes, leading to wasted computing resources and time, as each service validates requests based on its own specifications without access to downstream services' rules.
Innovation Solution
Implementing a centralized request validation system with a central validation server that stores and maintains request validation specifications for all domain services, allowing the gateway service to validate requests against multiple downstream services' specifications before invoking them, thereby enabling early error detection and reducing redundant processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each computerized service validates requests based on its own request validation specification, then the service can ensure its own data requirements are met, but validation occurs late in the process and computing resources are wasted by invoking downstream services unnecessarily
Solution Approach 1:
The gateway service performs preliminary validation by obtaining request validation specifications from multiple downstream computerized services before invoking them. This allows the gateway service to validate the request against all necessary specifications in advance, detecting invalid data early and avoiding unnecessary invocations of downstream services, thus reducing computing time while maintaining validation accuracy
2Ease of operation
If each computerized service stores its own request validation specification, then the service has access to its validation rules, but the validation scheme becomes tightly coupled to individual service implementations and lacks centralized control
Solution Approach 1:
The request validation specifications are extracted from individual computerized services and consolidated at the gateway service. This allows the gateway service to access and apply validation rules from multiple downstream services without tight coupling to their implementations, reducing system complexity while maintaining ease of operation through centralized validation management
