Solution Overview

Problem

Developing and managing application services in a cloud environment requires extensive coding for custom resource operators, leading to errors and inefficiencies, particularly in Kubernetes deployments, where multiple developers are needed to configure and integrate components, resulting in complex and error-prone processes.

Innovation Solution

The Custom Resource Abstraction and Fabrication Tool (CRAFT) architecture enables developers to create and manage application services with minimal coding by providing high-level configurations and abstractions, allowing a single developer to define custom resource operators and automate reconciliation, validation, and feedback processes, using Kubernetes operators and CRD structural schema validation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If extensive coding is used for custom resource operators, then functionality and control are improved, but complexity and error rate increase

Engineering Contradiction:

ImprovefunctionalityVSAvoidcomplexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces CRAFT as an intermediary tool that sits between the developer and the Kubernetes platform. Instead of developers directly writing complex operator code, CRAFT serves as a mediator that translates high-level service specifications into operational configurations, thereby reducing the coding burden while maintaining full functionality and control over the deployed services.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service through automated service fabrication. CRAFT automatically generates the necessary operator code, resource definitions, and deployment configurations based on service specifications provided by developers. This self-automating approach reduces manual coding requirements while maintaining adaptability and control, as the system serves itself by generating the operational artifacts needed for deployment.

Inventive Principle:

Principle #25Self-service

2Reliability

If multiple developers are used to configure and integrate components, then reliability is improved, but time consumption and coordination overhead increase

Engineering Contradiction:

ImprovereliabilityVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

CRAFT implements self-service by automatically generating service deployments and managing resource integration. The system takes service specifications as input and autonomously produces the complete deployment package, including operators, custom resource definitions, and configuration files. This eliminates the need for multiple developers to manually configure and integrate components, significantly reducing time consumption while maintaining reliability through automated validation and consistent generation processes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent incorporates feedback mechanisms where CRAFT validates service specifications against platform requirements and provides automated feedback on configuration correctness. This feedback loop enables single developers to identify and correct issues early in the specification phase, ensuring reliability without requiring extensive manual review and coordination among multiple developers, thereby reducing time consumption.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If manual configuration processes are used, then flexibility is improved, but productivity and efficiency decrease

Engineering Contradiction:

ImproveflexibilityVSAvoidproductivity

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

CRAFT implements self-service automation that maintains flexibility while dramatically improving productivity. The system automatically generates service deployments, configures resources, and manages integrations based on high-level specifications. This automated service fabrication eliminates manual configuration tasks, enabling single developers to deploy complex services quickly and efficiently while maintaining the flexibility to customize service behavior through specification-level control.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If high-level configurations and abstractions are used, then ease of use is improved, but control and customization capability may be reduced

Engineering Contradiction:

Improveease of useVSAvoidcontrol

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

CRAFT serves as an intermediary that translates high-level service specifications into detailed operational configurations. Developers interact with simple, high-level abstractions when defining services, while CRAFT automatically generates the necessary low-level Kubernetes resources, operators, and configurations. This intermediary approach maintains ease of use through high-level specifications while preserving full control and customization capability by generating precise operational artifacts that can be further modified if needed.

Inventive Principle:

Principle #24Intermediary (Mediator)
