Server Rotation by Address Reassignment for Low-Downtime Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server deployment systems face inefficiencies and uncertainties during transitions between test, staging, and production servers due to the need for manual modifications, additional testing, and downtime, especially when dealing with different certificates and database synchronization.
Innovation Solution
Implementing a system where test and production servers are rotated by address reassignment or DNS changes, using wildcard SSL/TLS certificates, and cloning machine images to minimize modifications, allowing seamless transitions with minimal downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual deployment and configuration changes are made during server transitions, then servers can be updated with new code and dependencies, but downtime and operational disruptions occur
Solution Approach 1:
The patent merges the test and production server configurations into a single unified server instance. By combining both environments in one server, the system can switch between test and production modes dynamically without requiring separate physical servers, thereby eliminating downtime associated with manual deployment and configuration changes.
Solution Approach 2:
The patent implements dynamic server configuration that allows the same server to dynamically switch between test and production roles. The server can change its operational state based on incoming requests or administrative commands, enabling seamless transitions without manual intervention or service interruption.
2Reliability
If separate test and production servers are maintained with different certificates and configurations, then secure https access can be provided for each environment, but additional configuration steps and complexity are required during rotation
Solution Approach 1:
The patent implements a universal server configuration that serves both test and production environments with a single SSL/TLS certificate. The server can handle secure HTTPS requests for both environments simultaneously, eliminating the need for separate certificate management and configuration for each environment.
Solution Approach 2:
The patent changes the operational parameters of the server dynamically rather than maintaining separate fixed configurations. By modifying runtime parameters such as environment variables, configuration files, or routing rules, the server can adapt its behavior for test or production modes without requiring structural configuration changes.
3Adaptability or versatility
If code and data are deployed to separate test and production servers, then development and testing can proceed independently, but synchronization and consistency between environments become difficult
Solution Approach 1:
The patent merges the data storage and code deployment into a single unified system for both test and production environments. By using a shared database and common codebase that both environments access, the system eliminates data synchronization issues while still allowing independent development through environment-specific configuration parameters.

AI summary
Systems and methods in the field of software development and workflows for networked applications. System would allow rotation of test, staging, and production servers by reassigning their respective addressing, with minimal or no modification to the servers. It would reduce or eliminate uncertainty, additional testing, delays, and downtime as a result of server rotation and maintenance.
