Grid Service SLA Compliance Monitoring via Execution Time Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grid technologies lack a mechanism to monitor and enforce service level agreements (SLAs) for timeliness, particularly in grid environments, which can lead to non-compliance and a lack of compensation for clients when performance guarantees are not met.
Innovation Solution
A grid service that monitors the execution time of grid jobs by starting a timer from the entry point to the exit point, calculates restitution fees for non-compliance, and awards bonus credits for timely execution, ensuring compliance with agreed-upon SLAs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If grid technologies are used to share and coordinate diverse resources in distributed environments, then resource sharing and coordination capability is improved, but there is no mechanism to monitor and enforce service level agreements for timeliness
Solution Approach 1:
The patent implements a feedback mechanism by monitoring the execution time of grid jobs and comparing it against SLA thresholds. When jobs exceed their allowed execution time, the system automatically triggers restitution actions. This closed-loop feedback system ensures that resource sharing operations maintain reliability by continuously verifying compliance and correcting deviations.
Solution Approach 2:
The patent introduces an intermediary monitoring component that sits between the grid job execution system and the resource management system. This intermediary tracks execution times, enforces SLA compliance, and manages restitution processes, thereby bridging the gap between resource sharing operations and compliance guarantees without disrupting the core grid functionality.
2Device complexity
If no SLA monitoring mechanism is implemented, then device complexity is reduced, but compliance with service level agreements cannot be enforced
Solution Approach 1:
The patent segments the SLA monitoring function into distinct modular components: a monitoring module that tracks execution times, an evaluation module that compares times against SLA thresholds, and a restitution module that executes compensation actions. This segmentation allows the system to add enforcement capability while maintaining manageable complexity through clear separation of concerns.
3Measurement precision
If execution time monitoring is implemented for all grid jobs, then SLA compliance detection is improved, but processing overhead increases
Solution Approach 1:
The patent applies local quality by implementing execution time monitoring selectively based on job characteristics and SLA requirements. Rather than uniformly monitoring all grid jobs, the system identifies which jobs require compliance tracking and applies monitoring only to those cases. This targeted approach maintains measurement precision for critical jobs while minimizing processing overhead across the entire system.
Data Source
AI summary
A computer-implemented method, system, and program for managing compliance with service level agreements in a grid environment are provided. A grid service for managing compliance with service level agreements in a grid environment detects a grid job passing a timing entry point, and flowing towards a grid environment provided by a grid vendor. When the grid job is detected passing the timing entry point, the grid service starts a timer to monitor an amount of time from the grid job passing the timing entry point until a result of the grid job passes a timing exit point while flowing away from the grid environment. When the grid service detects the result of the grid job passing the timing exit point, the grid service determines whether a value of the timer exceeds a timing term agreed to in a service level agreement specifying performance requirements for said grid job agreed to by said grid vendor, such that compliance with the service level agreement is automatically managed within the grid environment.
