Solution Overview

Problem

FaaS deployment faces challenges with cascading execution of functions leading to increased resource consumption, execution time, and low performance due to serial provisioning of functions, which can result in higher costs and inefficient resource utilization.

Innovation Solution

A system dynamically collects information on deployed functions and fuses them into a single container, using static or dynamic analysis to identify cascading function calls and optimize resource usage, reducing compute resources and improving performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If functions are deployed as separate containerized functions with cascading execution, then function modularity and independence are improved, but resource consumption and execution time increase

Engineering Contradiction:

Improvefunction modularityVSAvoidresource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple containerized functions that execute in cascade into a single fused container. The system identifies cascading function calls, packages their source code together into one image, and deploys them as a unified entity. This combining approach maintains the functional modularity benefits while reducing resource overhead by eliminating redundant container infrastructure for each function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fused container becomes a universal execution unit that can handle multiple function invocations internally. Instead of requiring separate container instances for each function call in the cascade, a single fused container handles all functions, making the container infrastructure universal and reducing overall resource consumption while preserving function independence through internal code organization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If functions are deployed as separate containerized functions with cascading execution, then function independence is improved, but execution time increases

Engineering Contradiction:

Improvefunction independenceVSAvoidexecution time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

By merging cascading functions into a single container, the system eliminates the time required for inter-container communication and sequential provisioning. The fused container executes functions in a unified process space, removing overhead associated with container lifecycle management between function calls while preserving logical function independence through code structure.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If functions are provisioned serially in cascade, then function deployment flexibility is improved, but productivity decreases

Engineering Contradiction:

Improvedeployment flexibilityVSAvoidexecution efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system combines serially-provisioned functions into a parallel-execution unified container. The fused container can execute multiple functions concurrently or in optimized sequences within a single process space, dramatically improving productivity by eliminating the serial provisioning bottleneck while maintaining deployment flexibility through the containerization framework.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If multiple separate container instances are used for cascading functions, then function isolation is improved, but device complexity increases

Engineering Contradiction:

Improvefunction isolationVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent reduces system complexity by merging multiple container instances into one fused container. This consolidation simplifies the deployment architecture, reduces the number of managed entities, and lowers operational complexity while maintaining function isolation through internal code boundaries and execution contexts within the unified container.

Inventive Principle:

Principle #5Merging (Combining)
