Solution Overview

Problem

Existing virtualization technologies are resource-intensive and have long startup times, while container technologies, although providing isolation, can occupy physical machine resources and require complex management, affecting stability and efficiency for applications with low isolation requirements.

Innovation Solution

Utilize a root file system configuration device to build a container image, package it into a static file data package, and deploy it on a target physical machine without requiring a container image building tool or orchestration system, using a customized root file system to provide a lightweight isolated environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If virtualization technology is used to create virtual machine instances, then application isolation is achieved, but resource consumption increases and startup time lengthens

Engineering Contradiction:

Improveapplication isolationVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the root file system into a packaged format that can be deployed independently. By dividing the file system into manageable packages that can be pre-built and distributed, the system achieves isolation without requiring full virtual machine instances, thereby reducing resource consumption while maintaining application isolation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts the essential isolation mechanism from the full virtualization stack by using a customized root file system package. This extraction removes unnecessary components (full OS, device drivers, etc.) while retaining the core isolation functionality, allowing applications to run in isolated environments without the overhead of complete virtual machine instances.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If container technology is used to package applications, then resource efficiency improves, but physical machine resources are occupied and management complexity increases

Engineering Contradiction:

Improveresource efficiencyVSAvoidmanagement complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent creates lightweight, disposable root file system packages that can be rapidly deployed and discarded. These packages are self-contained and do not require persistent container runtime infrastructure, eliminating the need for complex container orchestration systems while maintaining resource efficiency. Each package is independent and can be managed without sophisticated tooling.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The root file system packages are designed to be self-sufficient, containing all necessary dependencies and configuration files within the package itself. This self-service design eliminates the need for external container management systems to provision, configure, or monitor the application environments, significantly reducing management complexity while preserving resource efficiency.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If container image building tools and orchestration systems are deployed, then application deployment capability improves, but system stability decreases due to additional components

Engineering Contradiction:

Improvedeployment capabilityVSAvoidsystem stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the deployment functionality from complex container orchestration systems by using simple file package extraction. The root file system packages can be deployed using basic file extraction commands without requiring specialized deployment tools or orchestration infrastructure, thereby maintaining deployment capability while eliminating the stability risks associated with additional system components.

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If virtual machine instances are created for isolation, then application security is enhanced, but startup time increases

Engineering Contradiction:

Improveapplication securityVSAvoidstartup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-building and packaging the root file system in advance. The packages are prepared beforehand with all necessary files and configurations, allowing for rapid deployment without the need for time-consuming virtual machine boot processes. This pre-packaging approach maintains security isolation while dramatically reducing startup time.
