Remediation Auditor for Cloud VM Impairment Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud computing systems face impairments in virtual machines due to hardware or software faults, misconfiguration, and other factors, leading to reduced quality of service, and existing remediation methods may not effectively address the underlying causes of these impairments.
Innovation Solution
A remediation auditor is introduced to analyze the effectiveness of remediation operations in cloud computing systems, identifying the root causes of impairments and adjusting the remediation service to apply the most effective corrective actions, including replacing impaired virtual machines and notifying support authorities of potential faults in underlying systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remediation operations are performed frequently to correct impairments in virtual machines, then the reliability of cloud services is improved, but the complexity of the remediation system increases
Solution Approach 1:
The patent implements a feedback mechanism where the remediation auditor analyzes the effectiveness of remediation operations and provides feedback to adjust future remediation strategies. The system monitors whether impairments are successfully corrected and uses this information to tune the frequency and type of remediation operations, resolving the contradiction by making the system adaptive rather than statically complex
Solution Approach 2:
The remediation auditor automatically analyzes impairment data, determines remediation effectiveness, and adjusts remediation parameters without requiring external intervention. The system self-tunes by comparing pre and post-remediation impairment indicators and autonomously modifies remediation operation frequency and type, reducing the perceived complexity while maintaining high reliability
2Reliability
If remediation operations are performed to correct impairments, then the quality of service is improved, but the time required for remediation and analysis increases
Solution Approach 1:
The system performs preliminary actions by continuously monitoring and collecting impairment indicators before actual remediation is needed. The remediation auditor is pre-configured with analysis capabilities and thresholds, so when impairments occur, the system can quickly determine effectiveness without lengthy analysis delays, reducing the time loss while maintaining service quality
3Productivity
If the remediation service applies corrective actions without analysis, then the productivity is improved, but the manufacturing precision of remediation effectiveness decreases
Solution Approach 1:
The system applies partial analysis actions selectively - it performs full effectiveness analysis only when necessary to tune remediation parameters, while allowing routine remediation operations to proceed with standard procedures. The auditor samples and analyzes specific cases to determine if parameter tuning is needed, maintaining high productivity while ensuring sufficient precision through targeted analysis rather than exhaustive review of every remediation operation

AI summary
A system for mitigating operational impairment of a computer system includes a plurality of computing nodes. Each of the computing nodes includes a processor and memory coupled to the processor. The computing nodes are configured to: implement a plurality of computing devices; identify an impairment in operation of a first of the computing devices; execute a first remediation operation to mitigate the impairment; analyze operation of the first of the computing devices after execution of the first remediation operation to determine whether the first remediation operation is effective to mitigate the impairment; and change a frequency with which the first remediation operation is applied to mitigate the impairment based on whether the first remediation operation is deemed effective to mitigate the impairment.
