Cross-Domain Container Observation via Intermediary Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Domain restrictions in computing environments, while enhancing security, often interfere with the interoperation of containers from different domains, particularly when an application needs to observe changes in data objects across domain boundaries, leading to issues like notification throttling, concurrency conflicts, and scalability problems with ad-hoc synchronization techniques.
Innovation Solution
A device coordinates domain-restricted containers by creating an observed container on behalf of an observing container from a different domain, providing a message-passing communication interface to monitor data object updates and notify the observing container, thus enabling data object observation while respecting domain restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If domain restriction is applied to containers to enhance security, then security of the computing environment is improved, but interoperation between containers from different domains is worsened
Solution Approach 1:
The patent introduces an intermediary communication interface that mediates between domain-restricted containers. This interface allows containers to observe and interact with data objects from other domains without breaking domain restrictions, thus maintaining security while enabling interoperation. The intermediary manages cross-domain observations and notifications without requiring containers to directly communicate across domain boundaries.
2Adaptability or versatility
If ad-hoc notification techniques are used to enable container observation, then interoperation capability is improved, but implementation complexity and resource utilization are worsened
Solution Approach 1:
The patent implements a self-service observation mechanism where the communication interface automatically manages notification subscriptions, throttling, and delivery between containers. Instead of requiring developers to manually implement complex synchronization logic, the system autonomously handles observation registration, notification routing, and resource management, significantly reducing implementation complexity while maintaining observation capabilities.
3Adaptability or versatility
If ad-hoc synchronization techniques are used for data object monitoring, then observation functionality is improved, but scalability and resource utilization are worsened
Solution Approach 1:
The patent creates a universal communication interface that handles multiple observation and notification functions through a single standardized mechanism. This interface can manage observations across numerous containers and data objects using consistent protocols for subscription, notification, and throttling. The multi-functional design enables the system to scale efficiently by reusing the same infrastructure for diverse observation scenarios rather than implementing separate ad-hoc solutions for each case.
Data Source
AI summary
A device may feature a set of containers from different domains, where the containers are restricted from interoperation due to domain restrictions. The device may provide a communication interface that enables simple communication between containers, such as string-based message-passing. While adequate for some uses, it may be difficult to utilize the communication interface in an ad-hoc manner for more complex uses, such as enabling a first container to observe state changes in an object within a second container. Instead, the device may receive a request by an observing container to create an observed container that is associated with a different domain, and to observe a data object within the observed container. Accordingly, the device may monitor the data object on behalf of the observing domain, and upon detecting an update, may transmit a notification of the update to the observing domain through the communication interface between the domain-restricted containers.
