Unified Grayscale Testing via Request Tag Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grayscale testing modes lack flexibility, requiring separate rule configurations for each service involved in the full link, which complicates the testing process and reduces efficiency.
Innovation Solution
The solution involves a method and apparatus that determine a target environment and test version for a target service based on a request tag, allowing for flexible adaptation to complex grayscale release scenarios by isolating different versions and uniformly managing traffic requests, thereby simplifying the configuration and increasing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate rule configurations are made for each service involved in the full link, then the grayscale testing can be performed on each service, but the device complexity and configuration work increase significantly
Solution Approach 1:
The patent merges the grayscale testing configuration into a unified service deployment descriptor (yaml file) that covers all services in the full link. Instead of configuring each service separately, the deployment information includes a comprehensive grayscale rule set that applies to service 1, service 2, service 3 and any other services in the chain, thereby reducing configuration complexity while maintaining testing capability
Solution Approach 2:
The deployment descriptor serves multiple functions simultaneously: it defines service deployment configurations, specifies grayscale testing rules for all services, and provides routing information. This universal configuration file replaces multiple separate configuration files, reducing the overall system complexity while enabling comprehensive grayscale testing
2Reliability
If separate rule configurations are made for each service, then each service can be tested independently, but the time required for configuration and testing increases
Solution Approach 1:
The grayscale testing rules for all services are pre-configured in the deployment descriptor before deployment. The configuration includes all necessary routing rules, version information, and traffic splitting parameters for service 1, service 2, service 3 and other services in advance, eliminating the need for time-consuming post-deployment configuration and enabling immediate testing
3Productivity
If multiple versions are deployed without environment isolation, then resource utilization improves, but version interference occurs and testing reliability decreases
Solution Approach 1:
The patent segments the deployment environment into isolated environments for different versions using namespace separation. Each version (e.g., version 1.0, version 2.0) is deployed in its own namespace, preventing interference between versions while allowing concurrent operation. The routing rules direct traffic to appropriate namespaces based on grayscale parameters, maintaining both resource efficiency and testing reliability

AI summary
A method of information processing includes obtaining a traffic request for a target service. The traffic request includes a request tag. The method further includes determining a target environment that matches with the request tag and obtaining first deployment information of the target service. The first deployment information of the target service indicates one or more test versions of the target service to be tested, and one or more corresponding environments respectively deployed for the one or more test versions of the target service. The method also includes determining, from the one or more test version, a target test version that is deployed to the target environment and accessing the target service in the target test version in the target environment. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
