Resource Registry for Nondeterministic Cloud Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource management systems in deterministic environments face challenges in flexible resource allocation and communication between various applications, particularly in cloud computing, due to changing resource locations and differing APIs, leading to complex and error-prone configurations.
Innovation Solution
A nondeterministic operation execution environment with a resource registry that allows registration, updating, and unregistration of resources, providing a feedback feature for status updates, enabling flexible access and monitoring through a common API, decoupling operation requestors and executors, and allowing polling for operation status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct communication between operation requestors and executors is implemented, then operational control and status monitoring are improved, but system complexity and configuration difficulty increase
Solution Approach 1:
The patent introduces a resource registry as an intermediary component that decouples operation requestors from executors. The registry maintains resource information including URLs and APIs, allowing requestors to obtain executor locations without direct configuration. This mediator handles the complexity of resource location management while providing simple access to requestors.
Solution Approach 2:
The system segments the resource management functionality into separate components: the resource registry handles resource registration and information storage, while operation requestors handle operational tasks. This segmentation allows each component to be independently configured and managed, reducing overall system complexity.
2Adaptability or versatility
If resource locations are made dynamic and migratable, then system flexibility and scalability are improved, but communication reliability and configuration stability deteriorate
Solution Approach 1:
The resource registry implements a feedback mechanism where executors periodically update their location information and status with the registry. The registry maintains current resource URLs and API information, providing requestors with up-to-date communication channels. This feedback loop ensures communication reliability even as resources migrate or scale.
Solution Approach 2:
Executors autonomously manage their own location information by registering with the resource registry and updating their status. This self-service approach allows dynamic resource allocation and migration without requiring manual reconfiguration of requestors, maintaining communication reliability through automated information synchronization.
3Adaptability or versatility
If multiple different types of applications are allowed to access resources, then system versatility is improved, but configuration complexity and error-proneness increase
Solution Approach 1:
The resource registry serves as a universal access point for multiple different types of applications. It provides a standardized interface for registering and querying resource information, allowing diverse applications (CRM, ERM, cloud services) to access resources without application-specific configuration. This universal mechanism simplifies multi-application support.
4Adaptability or versatility
If different executors provide different APIs, then executor functionality and specialization are improved, but resource allocation flexibility and ease of operation deteriorate
Solution Approach 1:
The resource registry acts as an intermediary that abstracts away the differences in executor APIs. Requestors interact with the registry through a standardized interface to obtain resource information, while the registry handles the complexity of communicating with different executor APIs. This decoupling maintains executor specialization while simplifying resource allocation for requestors.

AI summary
A resource registry provides nondeterministic operation environment affording flexible access for resource execution and status monitoring on the cloud. The resource registry service provides generic resource management utilizing registration, updating, and unregistration by resource providers. A requester for an operation may register in the resource registry, an operation resource having parameters defined in metadata. The resource registry notifies a registered resource listener of this registration of the operation resource. The resource listener may then execute the operation according to parameters defined in the operation resource. The resource listener returns a response to the resource registry, concerning a result of execution of the operation. The resource registry updates this status in the metadata of the operation resource. The requester is then able to look up the operation resource's metadata to determine current status of the operation. The nondeterministic operation environment desirably avoids direct coupling between operation requestor and operation executor APIs.
