Disaster Recovery Alpha Node Coordination Across Distributed Data Lakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems and methods for managing applications and databases in enterprise environments lack sufficient intelligence for quick and reliable disaster recovery, leading to significant downtime and loss of critical data due to cyber-attacks or hardware/software failures.
Innovation Solution
A method for performing disaster recovery across geographically dispersed nodes, where an alpha node coordinates beta nodes, periodically checks their status, attempts to restore non-responsive nodes, notifies users of unsuccessful restoration, and updates the node order, ensuring seamless operation even if one or more nodes are attacked or fail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current systems and methods are used for managing applications and databases, then system operation is maintained, but significant downtime and loss of critical data occur during disasters or attacks
Solution Approach 1:
The system performs preliminary actions by pre-establishing multiple geographically dispersed nodes (alpha and beta nodes) that are ready in advance to take over if a failure occurs. The alpha node continuously monitors beta nodes, and the system maintains pre-configured restoration capabilities, so when a disaster strikes, the recovery process can begin immediately without waiting for system analysis or configuration setup.
Solution Approach 2:
The invention creates copies of the system across multiple geographically dispersed nodes. Each node maintains copies of databases and application states, allowing any node to potentially serve as a backup. When a node fails, the system can switch to a copied instance at another location, minimizing data loss and downtime.
2Reliability
If multiple geographically dispersed nodes are implemented for disaster recovery, then service continuity is improved, but system complexity increases
Solution Approach 1:
The system implements asymmetry by designating specific roles to different nodes: one alpha node and multiple beta nodes. The alpha node has special responsibilities (monitoring, coordination, initiating restoration) while beta nodes have simpler roles (being monitored, providing backup capacity). This asymmetric role distribution simplifies coordination compared to a fully symmetric peer-to-peer model, as there is a clear hierarchy and single point of control for disaster recovery operations.
Solution Approach 2:
The alpha node continuously receives feedback in the form of status signals from all beta nodes. This feedback mechanism allows the system to monitor node health in real-time and automatically trigger restoration procedures when failures are detected. The feedback loop enables automated decision-making and reduces the need for complex manual coordination protocols.
3Productivity
If automated restoration procedures are implemented, then recovery speed is improved, but false restoration attempts may occur
Solution Approach 1:
The system uses feedback from status signals sent by beta nodes to verify their actual state before initiating restoration. The alpha node monitors these signals continuously and only triggers restoration when genuine failure conditions are confirmed, reducing false positives. The feedback mechanism provides real-time verification that helps distinguish between temporary glitches and actual failures requiring restoration.
Solution Approach 2:
The system performs preliminary verification by analyzing status signals and determining node health conditions before initiating restoration procedures. This preliminary assessment step ensures that restoration is only triggered when truly necessary, preventing premature or false restoration attempts while maintaining rapid response capability once failure is confirmed.

AI summary
Embodiments described herein relate to methods, systems, and non-transitory computer readable mediums storing instructions for maintaining application instances or contexts across a plurality of geographically distributed nodes. These applications may take the form of web applications and/or databases that are exposed to the Internet and/or other unsecured networks. In order to prevent the loss of these applications due to cyber-attacks or due to day-to-day hardware and/or software failures, an alpha node is established and the remaining nodes are established as beta nodes. When any node goes down one or more embodiments of the invention allow for the orderly and continued operation of the remaining nodes.
