Solution Overview

Problem

Traditional systems for managing virtual server resources risk widespread disruptions due to undiscovered errors in new code versions, leading to operational failures, increased costs, and user dissatisfaction when deployed without adequate testing under real user interactions.

Innovation Solution

A computer-implemented system for test deployment of computational code on virtual servers, which selects a test virtual server, uploads and initializes the code, receives performance measurements, calculates a test score, and stops the code if it exceeds set thresholds, ensuring minimal disruption to user experiences by comparing resource usage with baseline servers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If computational code is mirrored across all virtual servers to standardize user experiences, then resource management is simplified and user experience consistency is improved, but the risk of widespread disruption increases when undiscovered errors in new code versions are deployed

Engineering Contradiction:

Improveresource managementVSAvoidoperational stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system segments the virtual server fleet into a control group (remainder servers) and a test group (single test server). This allows the new code to be tested on a isolated server before being mirrored to all servers, thus maintaining ease of management while reducing the risk of widespread disruption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary testing of the new computational code on a dedicated test server before deploying it to the production environment. This preliminary action allows undiscovered errors to be detected early, preventing them from causing widespread disruption across all servers.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If new code versions are deployed to test virtual servers for validation, then the ability to test with real user interactions is improved, but the risk of deleterious impacts on user experiences increases if errors are not detected

Engineering Contradiction:

Improvecode testing capabilityVSAvoiduser experience disruption

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system applies local quality by creating a dedicated test server environment with specific characteristics (isolated from production traffic) that allows safe testing of new code. This local test environment has different quality attributes from production servers, enabling thorough testing without impacting user experiences.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The test server acts as an intermediary between code development and production deployment. It provides a controlled environment where new code can be validated with real user interactions while isolating potential failures from the production user base, thus preventing deleterious impacts.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If computational performance measurements are collected and analyzed to determine code deployment, then the precision of deployment decisions is improved, but the complexity of monitoring and evaluation increases

Engineering Contradiction:

Improvedeployment decision accuracyVSAvoidmonitoring system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts the testing function from the production server environment by using a dedicated test server. This separation allows comprehensive performance measurements to be collected without the complexity of monitoring all production servers simultaneously, improving measurement precision while managing system complexity.

Inventive Principle:

Principle #2Taking out (Extraction)
