Configuration Lease System for Dynamic Software Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software systems require manual intervention and are time-consuming, error-prone, and unsuitable for containerized applications and dynamic deployment, as they necessitate static configuration files that are updated at compile-time.
Innovation Solution
A method for leasing decoupled configurations, where a unique configuration set is dynamically assigned to a client application at runtime, managed through a lease system that persists configuration changes and allows for dynamic scaling and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration parameters are locked in at compile-time through static configuration files, then the application can operate reliably on specific hardware, but the configuration cannot be changed without manual intervention, recompilation, and rebuilding
Solution Approach 1:
The patent implements dynamic configuration loading at runtime through a configuration server that provides configuration parameters to client applications during execution. This allows configuration to change without recompilation, resolving the contradiction between reliability (stable configuration) and adaptability (flexible configuration) by making the configuration dynamic rather than static.
Solution Approach 2:
The configuration parameters are extracted from the application binary and stored separately on a configuration server. The application loads configuration at runtime from this external source rather than having it compiled in, allowing the configuration to be modified independently of the application code, thus achieving both reliability and adaptability.
2Adaptability or versatility
If configuration files are edited manually and applications are recompiled, then configuration changes can be made, but the process is time-consuming and error-prone
Solution Approach 1:
The configuration server pre-loads and manages configuration parameters before the application needs them. Configuration changes are prepared and made available on the server beforehand, allowing the application to simply retrieve updated configuration at runtime without manual editing or recompilation, significantly reducing configuration update time.
Solution Approach 2:
The application automatically retrieves configuration parameters from the configuration server at runtime without requiring manual intervention. The system serves itself by loading configuration dynamically, eliminating the time-consuming manual edit-compile-build process.
3Reliability
If configuration is tied to physical or virtual hosts, then the application can operate on specific hardware, but the configuration cannot be used by other hosts or scaled dynamically
Solution Approach 1:
The configuration server provides a universal configuration service that can serve multiple client applications on different hosts. Instead of host-specific configuration files, the same configuration server can provide appropriate configuration to any client that connects to it, enabling both host-specific configuration stability and deployment scalability.
Solution Approach 2:
The configuration server acts as an intermediary between the application and the configuration parameters. Rather than the application being directly tied to host-specific configuration files, the configuration server mediates by providing configuration dynamically based on the client's needs, enabling scalability across multiple hosts while maintaining configuration stability.
4Stability of the object's composition
If static configuration files are used, then the application can maintain consistent configuration, but manual updates are required for any configuration changes
Solution Approach 1:
The application automatically retrieves configuration parameters from the configuration server at runtime without requiring manual updates. The system maintains configuration consistency through the server's controlled distribution of configuration parameters while making updates easy through automatic retrieval, eliminating the need for manual file editing.
Solution Approach 2:
The configuration server implements a feedback mechanism where configuration changes are pushed to or retrieved by client applications automatically. This ensures configuration consistency is maintained through centralized control while ease of operation is achieved through automated configuration distribution and updates.
Data Source
AI summary
Provided is a computer-implemented method, system, and computer program product for leasing decoupled configurations and managing configuration lease persistence with application state management including receiving a configuration set lease request from a client application in response to the client application being launched. In response to receiving the configuration set lease request, the method, system, and computer program product includes determining a unique configuration set from a pool of different configuration sets. Further, the method, system, and computer program product includes communicating the unique configuration set to the client application and activating a lease of the unique configuration set by associating the client application with the unique configuration set in a lease database. In response to determining that the lease is valid, persisting the lease in the lease database. In response to determining that the lease is invalid, deactivating the lease of the unique configuration set in the lease database.
