Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static resource provisioning is used for peak demand, then service performance is maintained during high loads, but resource utilization deteriorates and causes wasted money
Solution Approach 1:
The patent implements dynamic resource provisioning through autoscalers that automatically adjust computing resources based on real-time workload conditions. The system transitions from static peak-demand provisioning to dynamic scaling that adapts resource allocation to actual service needs, maintaining performance during high loads while reducing resources during low-utilization periods.
Solution Approach 2:
The system employs feedback mechanisms where autoscalers continuously monitor service performance metrics and resource utilization levels. This feedback loop enables the system to make informed scaling decisions, adjusting resources upward when performance degradation is detected and downward when resources are underutilized, thereby resolving the contradiction between maintaining performance and avoiding waste.
2Ease of operation
If manual heuristics and static thresholds are used for autoscaling, then resource adjustment can be controlled, but configuration complexity increases and requires significant time and expertise
Solution Approach 1:
The patent implements self-service capabilities where the system automatically generates and optimizes autoscaler configurations without requiring manual intervention. The service itself provides the configuration information needed for autoscalers, eliminating the need for software engineers to manually specify scaling conditions and reducing configuration complexity while maintaining controlled resource adjustment.
Solution Approach 2:
The system dynamically changes autoscaler parameters based on service characteristics and workload patterns. Instead of requiring manual specification of static thresholds and scaling factors, the system automatically adjusts these parameters according to actual service behavior, reducing the expertise required for configuration while maintaining precise control over resource adjustment.
3Adaptability or versatility
If reactive autoscaling approaches are used, then resource adjustments can be made based on current load, but quality of service deteriorates when demand changes faster than reconfiguration time
Solution Approach 1:
The patent implements preliminary action by using predictive analytics to anticipate future resource demands before they occur. The system analyzes historical workload patterns and service metrics to predict upcoming scaling needs, enabling resource adjustments to be prepared in advance rather than reacting after performance degradation occurs. This maintains quality of service even when demand changes rapidly.
Solution Approach 2:
The system transitions from purely reactive autoscaling to a dynamic approach that combines real-time monitoring with predictive capabilities. The autoscalers adapt to changing workload conditions by incorporating predictive insights, enabling the system to maintain high quality of service during rapid demand changes while preserving resource adaptability to various workload patterns.
4Ease of manufacture
If conventional predictive approaches like linear regression are used, then simple workload behavior can be captured, but scalability deteriorates and huge amounts of samples are required
Solution Approach 1:
The patent changes the parameters and methodology of predictive modeling by service-specific analysis. Instead of applying generic predictive approaches across all services, the system tailors predictive models to each service's unique characteristics and workload patterns. This improves scalability by making the predictive approach efficient for individual services while maintaining ease of implementation through automated service-specific model generation.

AI summary
A system and method for automatically adjusting computing resources provisioned for a computer service or application by applying historical resource usage data to a predictive model to generate predictive resource usage. The predictive resource usage is then simulated for various service configurations, determining scaling requirements and resource wastage for each configuration. A cost value is generated based on the scaling requirement and resource wastage, with the cost value for each service configuration used to automatically select a configuration to apply to the service. Alternatively, the method for automatically adjusting computer resources provisioned for a service may include receiving resource usage data of the service, applying it to a linear quadratic regulator (LQR) to find an optimal stationary policy (treating the resource usage data as states and resource-provisioning variables as actions), and providing instructions for configuring the service based on the optimal stationary policy.
