Policy Manager for Runtime Usage Analysis in Distributed Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current distributed computer systems face challenges in efficiently managing and analyzing policies applied to web service clients and services, particularly in maintaining accurate runtime usage associations and updating them in real-time, which can lead to incorrect system behavior and security vulnerabilities.
Innovation Solution
A policy manager component that creates, modifies, and deletes runtime representations of policy associations, generating usage analyses and updating them in real-time, even when the server is offline, ensuring accurate policy usage tracking and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If runtime usage associations are maintained manually without automated management, then system complexity is reduced, but policy usage accuracy deteriorates leading to incorrect system behavior
Solution Approach 1:
The policy manager automatically manages runtime usage associations without requiring manual intervention. The system self-updates usage associations by monitoring policy attachments and detachments in real-time, eliminating the need for manual tracking while maintaining high accuracy in policy usage information.
Solution Approach 2:
The policy manager implements a feedback mechanism that continuously monitors policy usage and automatically updates runtime usage associations. When policies are attached or detached from web services, the policy manager detects these changes and refreshes the usage associations accordingly, ensuring accuracy through continuous feedback loops.
2Speed
If policy associations are updated in real-time while server is online, then policy management responsiveness is improved, but system reliability may deteriorate due to concurrent access issues
Solution Approach 1:
The policy manager prepares and validates policy association updates before applying them to the running system. By pre-processing policy attachment and detachment operations and validating them before execution, the system achieves real-time responsiveness while preventing concurrent access conflicts and maintaining reliability.
3Loss of time
If runtime usage associations are not refreshed when server starts, then system startup time is reduced, but policy usage information becomes outdated
Solution Approach 1:
The policy manager performs preliminary loading of policy associations during system startup, preparing the runtime usage associations in advance. This preliminary action ensures that when the server becomes operational, the policy usage information is already current and accurate, avoiding both startup delays and information outdatedness.
4Reliability
If policy manager automatically manages runtime usage associations, then policy usage accuracy is improved, but device complexity increases
Solution Approach 1:
The policy manager is designed as a universal component that handles multiple policy management functions simultaneously - creating, modifying, deleting, and refreshing runtime usage associations. By consolidating these diverse functions into a single multi-functional component, the system achieves high policy usage accuracy without proportionally increasing overall system complexity.
Data Source
AI summary
In one set of embodiments, methods, systems, and apparatus are provided for determining, by a server, a policy association between a web service policy and a policy subject associated with an application hosted by the server, the policy association being made while the server is offline, generating a runtime usage association based on the policy association, wherein the runtime usage association is between the web service policy and the policy subject; and generating a user interface based upon the runtime usage association, the user interface displaying one or more web service policies associated with one or more policy subjects of the application. The runtime usage association may be updated in response to a change to the policy association made by an administrative tool, where the change and the updating occur in real time while the server is online.
