Cloud Outage Message Filtering via Inheritance Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud computing service chains, outages at lower-level cloud services can cause cascading outages and flooding of irrelevant or unfamiliar outage messages to consumers, compromising service reliability and consumer confidence.
Innovation Solution
Implementing an outage monitor system that applies inheritance rules to determine whether to pass on outage messages, with an option for human review and rendering of messages to align with consumer SLAs, ensuring only relevant information is communicated to consumers in a recognizable format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If outage messages are passed on through the entire cloud service chain, then complete information is provided to consumers, but irrelevant and unfamiliar outage messages flood the consumers
Solution Approach 1:
The patent introduces an intermediary component (outage message handler/filter) between the cloud service and consumers that selectively processes outage messages. This intermediary applies filtering rules to determine which outage messages should be passed through to consumers, blocking irrelevant messages while allowing critical information through, thus resolving the contradiction between information completeness and message flooding.
Solution Approach 2:
The patent applies different filtering criteria and message handling strategies to different types of consumers and different types of outage messages. Rather than a uniform approach, the system tailors the information flow to specific consumer needs and message characteristics, allowing relevant information to reach appropriate consumers while filtering out irrelevant content for each specific consumer context.
2Reliability
If all outage messages are forwarded to consumers, then transparency is maintained, but consumer confidence decreases due to unfamiliar message formats
Solution Approach 1:
The intermediary component not only filters outage messages but also translates and reformats them into consumer-friendly formats. This mediator layer maintains the transparency of outage information while presenting it in familiar, understandable formats that preserve consumer confidence, thus resolving the contradiction between transparency and message familiarity.
Solution Approach 2:
The patent changes the format, language, and presentation parameters of outage messages as they pass through the system. Outage messages are transformed from internal service formats to consumer-facing formats that are more understandable and familiar to end users, maintaining information integrity while improving consumer perception and confidence.
3Measurement precision
If manual review of outage messages is implemented, then message accuracy is improved, but response time to consumers decreases
Solution Approach 1:
The patent implements selective manual review rather than reviewing all outage messages manually. Automated filtering handles the majority of messages, with manual review applied only to specific cases that meet certain criteria or require human judgment. This partial automation approach maintains high accuracy for critical messages while minimizing overall delays.
Solution Approach 2:
The system implements feedback mechanisms where automated filtering decisions can be reviewed and corrected, and where consumer responses to outage notifications feed back into refining the filtering rules. This continuous feedback loop improves message accuracy over time while maintaining rapid automated response for routine cases.

AI summary
Various examples are directed to systems and methods for providing software services to one or more consumer systems. A cloud service provider system may receive a first outage message from a second cloud service provider system. The first outage message may describe a first outage of a first software service consumed by the first cloud service provider system and provided by the second cloud service provider system. The cloud service provider system may apply a set of outage inheritance rules to the first outage message and determine that the first outage is to be auto-reported. The cloud service provider system may render a revised first outage message and send the revised first outage message to a consumer system that receives a second software service provided by the cloud service provider system.
