Dynamic Resource Controller Lifecycle Management in Containerized Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Containerized systems face challenges in conserving system resources due to idle controllers and processes, as existing technologies cannot efficiently manage resource over-subscription and idle states within these systems.
Innovation Solution
A method is introduced that involves a master controller monitoring resource controllers in containerized systems. When a resource controller is determined to be idle, it is terminated, and the master controller watches for events specified in an event-criteria list. Upon detecting relevant events, the master controller recreates the resource controller, thereby optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource controllers are continuously running to monitor events, then system reliability is improved, but system resource consumption increases
Solution Approach 1:
The patent implements dynamic resource controller management by transitioning controllers between running and terminated states based on idle detection. The system dynamically adjusts resource controller lifecycle using event-criteria lists and idle determination logic, allowing controllers to be terminated when idle and recreated when events occur, thereby optimizing the balance between reliability and resource consumption
Solution Approach 2:
The system changes the operational state parameter of resource controllers from continuous running to conditional termination. By monitoring idle states and using parameters such as event-criteria lists and idle determination thresholds, the system transforms the static parameter of continuous operation into a dynamic state that adapts to actual workload requirements
2Loss of energy
If resource controllers are terminated when idle, then resource consumption is reduced, but system response time to events may increase
Solution Approach 1:
The system performs preliminary actions by maintaining event-criteria lists before termination and implementing rapid recreation mechanisms. When a resource controller is terminated, the system has already prepared the event-criteria list that the controller will monitor, enabling quick recreation and resumption of monitoring without significant delay in detecting subsequent events
3Productivity
If the system monitors and recreates resource controllers dynamically, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms through idle determination logic that continuously monitors resource controller states and triggers appropriate actions. The system uses event-criteria lists as feedback inputs to determine when controllers should be recreated, creating a closed-loop control system that automatically adjusts resource controller lifecycle based on actual system conditions without requiring complex manual management

AI summary
A method for conserving resources in a distributed system includes receiving an event-criteria list from a resource controller. The event-criteria list includes one or more events watched by the resource controller and the resource controller controls at least one target resource and is configured to respond to events from the event-criteria list that occur. The method also includes determining whether the resource controller is idle. When the resource controller is idle, the method includes terminating the resource controller, determining whether any event from the event-criteria list occurs after terminating the resource controller, and, when at least one event from the event-criteria list occurs after terminating the resource controller, recreating the resource controller.
