Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized orchestrator with static metrics is used for application assignment, then the system structure is simple and easy to implement, but the load distribution becomes suboptimal and scalability is limited
Solution Approach 1:
The centralized orchestrator is segmented into distributed computing nodes, each capable of independent suitability assessment. The monolithic decision-making structure is divided into multiple autonomous nodes that evaluate their own suitability for executing applications and communicate results through a messaging service, enabling parallel assessment and dynamic load distribution.
Solution Approach 2:
Static metrics in the centralized orchestrator are replaced with dynamic suitability assessments. Each computing node continuously evaluates its current resource availability, workload status, and suitability for executing applications, allowing the system to adapt to changing conditions in real-time rather than relying on predetermined static assignments.
2Ease of manufacture
If static metrics are used for application assignment decisions, then the implementation is straightforward, but the system cannot adapt to changing resource availability and current utilization
Solution Approach 1:
A feedback mechanism is introduced where computing nodes continuously assess their suitability for executing applications based on current resource availability and workload status. Suitability results are transmitted through a messaging service, creating a closed-loop system that adapts to changing conditions rather than relying on static predetermined assignments.
Solution Approach 2:
Each computing node performs self-assessment of its suitability for executing applications. Instead of a centralized controller making decisions based on static metrics, each node independently evaluates its own resource status, workload capacity, and suitability, enabling autonomous adaptation to changing system conditions.
3Device complexity
If conventional mapping solutions are used in heterogeneous clusters, then the system structure is simple, but the assignment of applications to computing nodes becomes problematic and inefficient
Solution Approach 1:
The patent applies local quality by allowing each computing node to have its own suitability assessment criteria and resource characteristics. In heterogeneous clusters where nodes have different capabilities, each node evaluates its own local resources and suitability independently, rather than applying a uniform mapping rule across all nodes. This enables optimal matching of applications to nodes based on local capabilities.
Solution Approach 2:
The system changes parameters dynamically by assessing suitability based on current resource availability, workload status, and node capabilities rather than using fixed static parameters. The suitability results transmitted through the messaging service reflect changing system state, enabling adaptive application assignment that accounts for heterogeneity in the cluster.
4Adaptability or versatility
If a decentralized distribution mechanism with dynamic assessment is implemented, then the adaptability and load distribution improve, but the system complexity and communication overhead increase
Solution Approach 1:
The messaging service acts as a universal communication infrastructure that handles multiple functions: transmitting suitability results, facilitating application assignment decisions, and enabling coordination between distributed nodes. This multi-functional component reduces overall system complexity by consolidating communication needs into a single standardized interface.
Solution Approach 2:
The messaging service serves as an intermediary between computing nodes, mediating the exchange of suitability results and application assignment information. This intermediary layer simplifies the decentralized architecture by providing a standardized communication protocol and buffer, reducing direct node-to-node complexity while enabling dynamic assessment and load balancing.

AI summary
A method for providing a distribution mechanism for distributing at least one application in a system of distributed computing nodes. Each of at least one of the computing nodes of the system performs the following assessment steps: receiving an application requirement from a request service, wherein the application requirement specifies at least one requirement of the application concerning at least one resource of the computing node, analyzing the received application requirement in order to compare the at least one requirement of the application with an availability of the at least one resource at the computing node, so as to ascertain a suitability result regarding a suitability of the computing node for executing the application, transmitting the ascertained suitability result to a messaging service in order to provide the suitability result at said messaging service together with further suitability results regarding the suitability of further computing nodes of the system.
