Automated Maintenance Scheduling for Containerized Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data centers with container orchestration systems, determining optimal maintenance times is challenging due to complex interactions between services and global user patterns, leading to potential significant downtime impacts on end users, especially in software-defined data centers where dependencies are dense and difficult to analyze manually.
Innovation Solution
An automated system that determines service dependencies and learns collective usage patterns to predict low-impact maintenance intervals by analyzing resource utilization and network interactions, providing a recommended maintenance schedule that minimizes overall impact across dependent services.

Engineering Contradiction Analysis
1Object-affected harmful factors
If maintenance is performed during off-peak hours to reduce user impact, then user experience is improved, but determining optimal times becomes complex and error-prone due to global user patterns and service dependencies
Solution Approach 1:
The patent introduces an automated maintenance scheduling system that acts as an intermediary between maintenance needs and user impact. This system analyzes service dependencies, collects usage metrics globally, and automatically determines optimal maintenance windows, eliminating the complexity of manual analysis while protecting user experience.
Solution Approach 2:
The system implements feedback loops by continuously collecting usage metrics from global users and analyzing service dependencies. This feedback enables the automated scheduling system to learn from actual user patterns and adjust maintenance timing decisions to minimize impact, transforming the complex decision-making process into an automated adaptive system.
2Ease of operation
If manual analysis of service dependencies is performed, then some maintenance scheduling can be achieved, but the dense interdependencies in software-defined data centers make manual analysis infeasible and error-prone
Solution Approach 1:
The patent replaces the mechanical process of manual dependency analysis with an automated computational system. The system automatically traverses service dependency graphs, collects usage metrics, and calculates optimal maintenance windows, substituting human analytical effort with automated algorithms that can handle the complexity of dense service interdependencies in software-defined data centers.
Solution Approach 2:
The maintenance scheduling system performs self-service by automatically analyzing its own service dependencies and usage patterns. The system collects metrics from itself and other services, traverses the dependency graph, and generates maintenance recommendations without external intervention, making the complex analysis process transparent and automated.
3Ease of manufacture
If broadcast approaches are used for maintenance scheduling, then simple implementation is achieved, but significant downtime impact on end users occurs due to lack of optimized timing
Solution Approach 1:
The patent applies preliminary action by pre-analyzing service dependencies and collecting usage metrics before maintenance is needed. The system determines optimal maintenance windows in advance based on learned user patterns and dependency analysis, allowing maintenance to be scheduled at optimal times rather than using simple broadcast approaches that cause unnecessary downtime impact.
