DNS Domain Failover Using Backup Data Center Replicas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud service providers face challenges in seamlessly integrating separate identity management systems for IaaS and SaaS/PaaS services, leading to unsatisfactory customer experiences and obstacles in service interactions, and there are inefficiencies in data center failover processes that cause significant delays in user transfer during data center unavailability.
Innovation Solution
Implementing an integrated identity management platform that transparently combines IAM and IDCS systems, and utilizing DNS addresses to automatically redirect users to backup data centers with replicated domains for faster failover, minimizing service disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legacy approaches of transferring a user to another data center are used, then service availability is maintained, but the transfer time is significant and causes service disruption
Solution Approach 1:
The patent applies preliminary action by pre-establishing backup data centers with replicated domains before any failure occurs. When a data center becomes unavailable, the system can immediately redirect users to the pre-prepared backup data center, eliminating the time-consuming transfer process of legacy approaches while maintaining service availability.
Solution Approach 2:
The patent uses an intermediary mechanism in the form of a unified DNS-based address that abstracts the underlying data center location. This intermediary address automatically resolves to the appropriate data center (primary or backup), enabling seamless user redirection without requiring users to be explicitly transferred, thus reducing transfer time while maintaining reliability.
2Adaptability or versatility
If separate identity management systems (IAM and IDCS) are used for IaaS and SaaS/PaaS services, then service specialization is achieved, but integration complexity increases and customer experience deteriorates
Solution Approach 1:
The patent merges separate identity management systems (IAM for IaaS and IDCS for SaaS/PaaS) into a unified identity management platform. This consolidation maintains the specialized functionality of each system while eliminating integration complexity, allowing seamless cross-service authentication and improving customer experience without sacrificing service specialization.
Solution Approach 2:
The patent creates a universal identity management platform that can handle authentication and authorization across multiple service types (IaaS, SaaS, PaaS) through a single system. This multi-functional approach replaces multiple specialized systems, reducing integration complexity while maintaining adaptability to different service requirements.
Data Source
AI summary
An approach of performing data center failover using an address that indicates a backup data center. The address includes common names indicating a data center with a domain and a backup datacenter with a replica of the domain. A cloud service provider can receive the address, establish a connection with an available data center, and failover to the backup data center if the data center with the connection becomes unavailable.
