Configuration Drift Reconciliation for SDDC Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern Software-Defined Data Center (SDDC) managers lack visibility and unified configuration management for SDDC resources, leading to issues with configuration drift, where custom configurations are overridden during updates, causing errors and reducing reliability.
Innovation Solution
The implementation of a configuration drift reconciliation orchestrator and reconciler service, which allows for on-demand, selective reconciliation of configuration updates and fixes at different resource granularities, detects anomalous configuration drifts, and enables policy-based remediation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration updates are applied during SDDC manager updates, then system functionality is improved, but configuration drift occurs causing reliability degradation
Solution Approach 1:
The patent implements a pre-update reconciliation phase that detects and resolves configuration drifts before the actual SDDC manager update is applied. This preliminary action ensures that custom configurations are identified and preserved beforehand, preventing configuration drift from occurring during the update process. The system performs a dry-run reconciliation that maps custom configurations to update packages and determines compatibility before execution.
Solution Approach 2:
The patent establishes a feedback mechanism where the system continuously monitors configuration states, detects drifts, and triggers reconciliation processes. The reconciliation service provides feedback about configuration compatibility and drift status, enabling the system to adjust update execution accordingly. This feedback loop ensures configuration consistency is maintained while allowing necessary updates to proceed.
2Reliability
If custom configurations are preserved during updates, then reliability is improved, but update execution time increases
Solution Approach 1:
The patent implements selective reconciliation that focuses only on configurations relevant to the specific update package being applied. Rather than reconciling all configurations comprehensively, the system performs partial reconciliation targeted at the subset of configurations that may be affected by the current update. This reduces unnecessary processing time while maintaining reliability for the configurations that actually matter.
Solution Approach 2:
The patent segments the configuration management process into distinct phases: pre-update reconciliation, update execution, and post-update verification. Each phase handles specific tasks independently, allowing parallel processing and optimization. The reconciliation service is segmented into multiple components that can process different configuration types simultaneously, reducing overall reconciliation time while preserving configuration stability.
3Measurement precision
If comprehensive configuration monitoring is implemented, then configuration drift detection accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a unified configuration management framework that serves multiple functions: monitoring, detecting, reconciling, and verifying configurations. The reconciliation service acts as a multi-functional component that can perform drift detection, compatibility assessment, and configuration mapping through a single integrated system. This universal approach improves detection accuracy without proportionally increasing complexity, as one system handles multiple tasks.
Solution Approach 2:
The patent introduces a configuration reconciliation service as an intermediary layer between the SDDC manager and the configuration data. This mediator component abstracts the complexity of comprehensive monitoring by providing a standardized interface for drift detection and reconciliation. The intermediary handles the complex logic of comparing configurations, identifying drifts, and determining compatibility, while presenting a simplified interface to other system components.
4Ease of operation
If selective reconciliation at different resource granularities is enabled, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic reconciliation system that can adapt its granularity and scope based on operational needs. The system can switch between different levels of abstraction (individual resources, resource pools, or entire SDDC environments) and adjust the depth of reconciliation accordingly. This dynamic capability allows operators to choose the appropriate level of detail for each operation, improving ease of use while the system internally manages the complexity of handling multiple granularities.
Solution Approach 2:
The patent provides pre-update reconciliation planning that allows operators to review and approve configuration changes before they are applied. This preliminary review process simplifies operation by giving operators visibility and control over what will be reconciled, at what granularity, and with what impact. The system prepares reconciliation plans in advance, allowing operators to make informed decisions without dealing with the complexity of real-time reconciliation logic.
