Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity and variability of software deployments in datacenters lead to challenges such as unpredictable failures, unplanned downtimes, poor resource utilization, and difficulties in maintaining standardized configurations, due to the ever-increasing number of software versions and patch levels.
Innovation Solution
A standardization management system that recommends and manages standardized configuration levels across different target software deployments by generating software configuration signatures, normalizing patches, and maintaining gold images to ensure compliance and reduce drift, thereby optimizing resource utilization and improving manageability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of software deployments and versions increases to meet diverse business needs, then adaptability and versatility improve, but device complexity and difficulty of managing standardized configurations worsen
Solution Approach 1:
The patent applies parameter changes by transforming software configuration states into standardized parameters that can be measured, compared, and managed. Configuration drift is detected by comparing actual configuration parameters against baseline parameters, enabling systematic management of software diversity through parameterized control rather than ad-hoc management
Solution Approach 2:
The patent implements feedback mechanisms by continuously monitoring software configuration states and comparing them against standardized baselines. When drift is detected, the system generates alerts and enables corrective actions to restore compliance, creating a closed-loop feedback system that maintains configuration standards across diverse deployments
2Ease of operation
If ad-hoc changes are made frequently to address system issues, then ease of operation improves, but reliability worsens due to unpredictable failures
Solution Approach 1:
The patent applies preliminary action by establishing standardized configuration baselines and policies before ad-hoc changes are made. The system pre-defines acceptable configuration states and compliance rules, so that when changes are needed, they can be evaluated against these pre-established standards rather than creating uncontrolled drift
Solution Approach 2:
The patent implements feedback by continuously monitoring configuration changes and alerting when drift occurs. This enables operators to see the impact of ad-hoc changes in real-time and take corrective action to restore compliance, preventing accumulation of unstable configurations
3Adaptability or versatility
If software configurations are allowed to drift across deployments, then adaptability to local needs improves, but manufacturing precision of standardized configurations worsens
Solution Approach 1:
The patent applies local quality by allowing targeted, controlled deviations from standard configurations at specific locations (individual deployments) while maintaining overall standardization. Configuration baselines can be customized for specific environments while maintaining core standardized elements, enabling local adaptation without sacrificing global precision
Solution Approach 2:
The patent implements feedback by continuously comparing actual configurations against baselines and detecting drift. This enables organization of configurations into compliance groups based on their drift status, allowing systematic management of standardized versus customized deployments
