Solution Overview

Problem

Serverless computing platforms face challenges with cold starts and developer experience due to the need for manual management of single-purpose functions, which slows down adoption and increases resource usage inefficiencies.

Innovation Solution

A parsing tool that automatically decomposes source code files containing multiple functions into single-purpose functions by analyzing syntax trees, creating mapping tables, and generating optimized output files for efficient deployment on serverless platforms, allowing developers to maintain a familiar coding experience while optimizing for serverless architectures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If developers use single-purpose functions in serverless computing, then resource usage efficiency improves, but developer experience and productivity deteriorate due to manual management overhead

Engineering Contradiction:

Improveresource usage efficiencyVSAvoiddeveloper experience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system automatically segments multi-function source code files into separate single-purpose function files. The parsing tool analyzes the source code, identifies individual functions, and generates separate deployment files for each function, enabling resource-efficient serverless deployment without requiring manual code segmentation by developers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The parsing tool performs automated code analysis and transformation, allowing the system to serve itself in converting multi-function code to single-purpose functions. This self-service capability eliminates the need for developers to manually manage function segmentation, thereby improving both resource efficiency and developer experience.

Inventive Principle:

Principle #25Self-service

2Use of energy by moving object

If developers manually create single-purpose functions, then resource usage efficiency improves, but development time and productivity worsen

Engineering Contradiction:

Improveresource usage efficiencyVSAvoiddevelopment time

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The parsing tool performs preliminary automated analysis of source code files before deployment, identifying and separating functions in advance. This preliminary action converts multi-function code into deployable single-purpose function files automatically, eliminating manual intervention and significantly reducing development time while maintaining resource efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces the mechanical manual process of creating single-purpose functions with an automated parsing tool that uses syntax tree analysis and mapping table generation. This substitution eliminates repetitive manual work, accelerates the development process, and maintains the resource efficiency benefits of single-purpose functions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If multi-function source code files are deployed directly, then developer experience improves, but cold start time increases

Engineering Contradiction:

Improvedeveloper experienceVSAvoidcold start time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The parsing tool segments multi-function source code into separate single-purpose function files, each with a focused scope and minimal dependencies. This segmentation reduces the initialization overhead for each function, thereby decreasing cold start time while allowing developers to continue using multi-function source files for development convenience.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system extracts individual functions from multi-function source code files and creates separate deployment units. By taking out each function as an independent single-purpose function, the system reduces the amount of code that needs to be loaded and initialized during cold start, thereby reducing cold start time while preserving developer-friendly multi-function source code structure.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A computer-implemented method that automatically parses an input source code files containing multiple functions to create one or more files, each containing a single-purpose function, for deployment on a serverless computing platform, such as Function-as-a-Service (“FaaS”), is disclosed herein. The method includes receiving an input source code file and creating a mapping table from the input source code file. A first function from the input source code file is mapped and a single-function output file for the first function is generated. The single-function output file is then deployed, for example, on the serverless computing platform.
