Virtualization Platform Updates Through Reserved-Node Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtualization platform software updates and migrations require additional resources, especially in edge computing environments with limited resources, and existing methods like blue-green and rolling updates have inefficiencies.
Innovation Solution
A method involving preparation of reserved nodes, forming a second virtualization platform on these nodes, migrating applications, and repeating this process until all nodes are updated without requiring additional resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If blue-green method is used for virtualization platform software update, then update time is shortened, but additional resources are required
Solution Approach 1:
The update process is segmented into multiple phases: selecting reserved nodes, forming new virtualization platforms on selected nodes, migrating applications, and repeating until completion. This segmentation allows incremental updates without requiring full additional resources like blue-green deployment.
Solution Approach 2:
Reserved nodes are pre-selected and prepared before the update process begins. These nodes are identified in advance as suitable candidates for hosting new virtualization platforms, enabling smoother transitions without resource conflicts during migration.
2Quantity of substance
If rolling update method is used for virtualization platform software update, then additional resources are not required, but update time is extended
Solution Approach 1:
The system performs preliminary selection of reserved nodes before migration begins. This advance preparation enables more efficient migration paths and reduces the overall update time compared to traditional rolling updates that process nodes sequentially without optimization.
Solution Approach 2:
The update process dynamically selects which nodes to update next based on system state and migration progress. Rather than following a fixed sequential order, the system adapts its update sequence to optimize resource utilization and reduce total update time.
3Productivity
If virtualization platform software is updated in edge servers with limited resources, then resource constraints are encountered, but efficient update is required
Solution Approach 1:
The update system manages its own resource allocation by selecting reserved nodes from within the existing infrastructure. It identifies and utilizes available capacity on specific nodes without requiring external resource provisioning, enabling efficient updates in resource-constrained edge environments.
Solution Approach 2:
The system applies different update strategies to different nodes based on their local characteristics and resource availability. Reserved nodes are selected based on their specific capacity and suitability, allowing optimized update execution across heterogeneous edge server environments.

AI summary
An information processing apparatus performs preparation process, first formation process, migration process, second formation process, and control process. The preparation process includes preparing, as a reserved node, one or more nodes in which one or more applications are not built on a first virtualization platform among a plurality of nodes in which the first virtualization platform is formed. The first formation process includes forming a second virtualization platform in the reserved node. The migration process includes migrating the one or more applications built on the first virtualization platform formed in a first node among the plurality of nodes to any second node among the one or more nodes in which the second virtualization platform is formed. The second formation process includes forming the second virtualization platform in the first node. The control process includes performing control to repeat the migration process and the second formation process.
