Solution Overview

Problem

Existing methods for resolving configuration conflicts in virtual machines (VMs) within cloud computing environments are costly and time-consuming, often requiring system rebooting and manual interventions, especially when multiple conflicting configurations are present.

Innovation Solution

An automated configuration validation and testing system that performs configuration conflict resolution by determining a subset of changes to be committed, using a dynamic match ordering methodology to merge configurations efficiently and restore the VM state through lightweight restoration without rebooting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional configuration conflict resolution methods are used, then system reliability is maintained through manual validation, but time consumption and operational complexity increase significantly

Engineering Contradiction:
Improveconfiguration correctnessVSAvoidconfiguration resolution time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary validation by computing configuration hashes and identifying differences before actual configuration changes are applied. This allows the system to detect conflicts early in the process, before they can cause system failures, thereby maintaining reliability while reducing the time needed for actual resolution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The configuration management system automatically detects conflicts, validates configurations, and resolves issues without requiring manual intervention. The system self-validates configuration integrity through hash computation and automatic rollback mechanisms, eliminating the need for manual validation while ensuring configuration correctness.

Inventive Principle:
Principle #25Self-service

2Stability of the object's composition

If complete configuration reloading is performed to resolve conflicts, then system state consistency is ensured, but service interruption and downtime increase

Engineering Contradiction:
Improvesystem state consistencyVSAvoidservice availability
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The system segments the configuration validation process into distinct phases: hash computation, difference identification, conflict detection, and selective rollback. This segmentation allows the system to validate only the specific configuration portions that changed, rather than reloading entire configurations, thereby maintaining consistency while minimizing service interruption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies local validation by computing hashes for specific configuration files and identifying only the differences in those particular files. When conflicts are detected, rollback operations are performed locally on only the affected configuration portions rather than system-wide configuration reloading, preserving service availability while ensuring local consistency.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If manual configuration validation and testing is performed, then configuration accuracy is improved, but operational complexity and resource requirements increase

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidvalidation system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system replaces manual configuration validation with automated computational methods. Configuration hashes are computed algorithmically, differences are identified through automated comparison, and conflicts are detected through systematic validation rules. This substitution of mechanical manual processes with automated computational systems maintains high configuration accuracy while reducing operational complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Speed

If configuration changes are applied without validation, then deployment speed increases, but system failure risk increases

Engineering Contradiction:
Improveconfiguration deployment speedVSAvoidsystem stability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary hash computation and configuration validation before changes are deployed. By calculating configuration hashes and identifying differences in advance, the system can quickly validate configurations during deployment without slowing down the process. This preliminary validation ensures system stability is maintained while deployment speed is preserved.

Inventive Principle:
Principle #10Preliminary action

AI summary

An automated toolset performs configuration conflict resolution for virtual machines (VMs) providing services in a networked cloud computing system by determining a set of changes to be committed through a series of automated actions. The toolset resolves conflicts among multiple possible configurations that could result in an incorrect VM state and merges configurations in view of inputs from internal and external systems. The toolset operates to identify only a subset of changes that differ between current and new configurations that are loaded into the system to streamline configuration loading and provide for lightweight restoration by rolling back only those differences. Further efficiencies are achieved using an automated test suite environment that is specially adapted to test and validate new configurations to ensure correct loading and avoid system failures.
