QoS Envelope for Dynamic Resource Allocation and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large data centers face inefficiencies in resource allocation and security threats from malicious software, leading to administrative overhead due to false positives and resource mismanagement.
Innovation Solution
Implementing a Quality-of-Service (QoS) envelope managed by a QoS agent that enforces resource allocation policies, predicts future resource usage, and generates security events for malicious activity, while queuing and metering excessive resource requests to maintain efficient operation and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security tools are used to prevent malicious software, then security protection is improved, but false positive results increase leading to greater administrative overhead
Solution Approach 1:
The system enables applications to self-regulate their resource consumption through embedded QoS agents that automatically monitor and control resource usage without requiring external security tool intervention, thereby reducing false positives and administrative overhead while maintaining security
Solution Approach 2:
The QoS agent continuously monitors resource usage and provides feedback to adjust resource allocation dynamically, creating a closed-loop system that prevents malicious behavior without generating false positives that require administrative intervention
2Productivity
If resource allocation is made more efficient through centralized management, then productivity is improved, but system complexity increases
Solution Approach 1:
The system divides resource management into distributed QoS agents on each application and a central QoS manager, allowing local decision-making that reduces communication overhead and system complexity while maintaining centralized policy enforcement for efficient resource allocation
Solution Approach 2:
The QoS envelope is dynamically adjusted based on real-time resource usage patterns and predicted future needs, allowing the system to adapt resource allocation efficiently without requiring complex static configuration management
3Productivity
If QoS envelope strictly enforces resource ceilings, then resource allocation efficiency is improved, but application performance may deteriorate when resources are needed
Solution Approach 1:
The QoS envelope dynamically adjusts resource ceilings based on predicted future resource usage and actual consumption patterns, allowing applications to receive adequate resources when needed while maintaining overall allocation efficiency through continuous adaptation
Solution Approach 2:
The system performs preliminary resource allocation based on predicted future usage before actual resource demands occur, ensuring applications have necessary resources available while preventing over-allocation that would reduce overall system efficiency

AI summary
A managed node executes one or more applications. The applications utilize the resources of the node. A quality-of-service (QoS) agent on the managed node enforces a QoS policy for the node. The QoS agent characterizes an application's usage of the node's resources and predicts its future usage. The QoS agent analyzes the predicted resource usage in view of the QoS policy and generates a QoS envelope for the application. The QoS envelope specifies a ceiling on the level of resources that can be used by the application. The QoS agent queues and meters usage above the ceiling specified by the QoS envelope. A security module determines variations between predicted and actual resource usage and generates security events if warranted.
