Configuration Change Planning for Application-Aware VM Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infrastructure management systems fail to recognize and manage configuration changes across multiple layers of an IT infrastructure, leading to potential destruction of system environments during operations like VM migration due to lack of application setting information reference.
Innovation Solution
A configuration change support apparatus and method that includes a storage device and processing device to manage IT infrastructure configuration information, application dependency information, and create additional configuration change information to minimize application impact, notifying users of potential effects and necessary changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If configuration changes are made without recognizing application setting information, then migration speed and operational simplicity are improved, but system reliability deteriorates due to potential destruction of system environment
Solution Approach 1:
The system performs preliminary analysis of application setting information before executing configuration changes. The processing device acquires and analyzes application setting information that describes storage configuration, identifying dependencies between applications and infrastructure components. This preliminary action enables the system to predict potential impacts and prepare appropriate measures before migration occurs, thus maintaining reliability while enabling efficient migration.
Solution Approach 2:
The system implements feedback by notifying the configuration change maker about the effects on applications. The processing device creates and communicates effect information that describes how configuration changes will impact running applications. This feedback loop allows operators to make informed decisions about whether to proceed with changes, modify them, or delay them, thereby preventing system environment destruction while maintaining migration productivity.
2Reliability
If application setting information is analyzed for every configuration change, then system reliability is improved by preventing environment destruction, but device complexity increases due to additional information processing requirements
Solution Approach 1:
The system extracts only the necessary application setting information related to the specific configuration change being considered. Rather than analyzing all application settings comprehensively, the processing device identifies and extracts only those settings that describe storage configuration and have potential relevance to the planned change. This extraction approach maintains reliability by focusing on critical information while reducing processing complexity by eliminating unnecessary analysis.
Solution Approach 2:
The system changes the parameter of information analysis from comprehensive to targeted based on the type of configuration change. The processing device adjusts the depth and scope of application setting information analysis according to the specific migration or configuration operation planned. For example, storage migration triggers storage-related setting analysis, while VM migration triggers compute-related setting analysis, thereby maintaining safety while reducing overall processing complexity.
Data Source
AI summary
A configuration general management server includes a storage device and a processing device. The storage device stores IT infrastructure configuration information indicating physical connections and logical connections and arrangement information of resources constituting the IT infrastructure, and application dependency information indicating dependency of an application being executed by a host on the IT infrastructure. The processing device acquires configuration change information, creates additional configuration change information to minimize an effect on the application if a configuration change based on the configuration change information is made, according to the configuration change information, the IT infrastructure configuration information, and the application dependency information, creates an application effect element indicating an effect on the application if a configuration change based on the configuration change information and the additional configuration change information is made, and notifies a configuration change maker of the application effect element and the additional configuration change information.
