Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for managing network-based failover services are overly complicated, increase design work for customers, and lack features that provide customer visibility and control, leading to inefficient failover workflows and potential data integrity issues.
Innovation Solution
A system for managing network-based failover services that coordinates failover workflow design and execution, allowing customers to manually or automatically remediate unavailable regions to meet availability requirements, using processing rules to identify and characterize available failover regions based on capacity, location, and other criteria, ensuring data integrity and application availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing mechanisms for managing network-based failover services are used, then failover services can be provided, but the management becomes overly complicated and design work for customers increases
Solution Approach 1:
The patent introduces a failover management service as an intermediary component that sits between customers and the complex failover infrastructure. This service abstracts and simplifies the management of failover workflows, region characterization, and remediation processes, allowing customers to manage failover services without dealing with the underlying complexity of region coordination, capacity management, and failover execution mechanisms.
2Ease of operation
If manual failover management is implemented, then customer control is increased, but customer interaction during failures increases
Solution Approach 1:
The patent implements preliminary action by requiring customers to pre-configure their failover workflows, region preferences, and remediation policies before failures occur. The failover management service stores these preferences and automatically executes them when failures happen, eliminating the need for customer interaction during actual failover events. This allows customers to maintain control over failover behavior while avoiding time-consuming interactions during critical failure moments.
3Speed
If failover regions are not properly characterized, then failover can occur quickly, but data integrity issues may arise
Solution Approach 1:
The patent applies preliminary action by implementing a region characterization process that evaluates and validates failover regions before they are needed. The failover management service assesses regions based on multiple criteria including capacity, data synchronization status, and operational readiness. This pre-characterization ensures that when failover is triggered, the system can quickly identify suitable regions while guaranteeing data integrity requirements are met, thus achieving both speed and reliability.
4Productivity
If elastic computing resources are dynamically scaled, then resource efficiency is improved, but system architecture complexity increases
Solution Approach 1:
The patent implements universality by designing the failover management service to handle multiple functions within a single unified system. It simultaneously manages failover workflow coordination, region characterization, capacity optimization, remediation processes, and customer preference management. This multi-functional approach consolidates what would otherwise require separate complex systems, achieving resource efficiency while managing architecture complexity through a unified service layer.

AI summary
The present disclosure generally relates to managing a failover service for regions in an active-active configuration. The failover service can receive a list of regions and a list of rules that must be satisfied for a region to be considered available for failover. For each primary region of a plurality of primary regions, the failover service can then determine the regions that satisfy each rule of the list of rules and are available for failover. The failover service can then deliver this information to a client. The failover service can determine the regions that do not satisfy one or more of the rules from the list of rules and deliver this information to a client. The failover service can perform automatic remediation and client remediation to the unavailable failover regions.
