Hybrid Cloud Disaster Recovery Orchestration for Active-Passive Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no automatic active-passive disaster recovery solution for digital hybrid cloud computing infrastructures, where a private cloud is connected to a public cloud, and existing manual solutions are not compatible with the concept of end-to-end automation in current digital hybrid cloud products.
Innovation Solution
A digital hybrid cloud computing infrastructure is designed with one active and one passive site, each connected to a public cloud, featuring a replication module, management domain, and a cloud orchestrator to automate disaster recovery by replicating storage resources and synchronizing recovery plans across sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual active-passive disaster recovery is implemented, then disaster recovery protection can be established, but it is not compatible with end-to-end automation concept
Solution Approach 1:
The system enables self-service automation where the cloud orchestrator automatically discovers protected virtual machines, retrieves their configurations, and executes recovery operations without requiring manual intervention. The site recovery manager modules automatically synchronize disaster recovery configuration information between sites through the cloud orchestrator, eliminating the need for manual setup while maintaining full automation capability.
Solution Approach 2:
The system implements feedback mechanisms where the cloud orchestrator receives disaster recovery configuration requests from the public cloud, processes them, and updates site recovery manager modules accordingly. This feedback loop enables automatic configuration synchronization and ensures that disaster recovery settings are automatically updated across both sites without manual reconfiguration.
2Extent of automation
If automatic active-active disaster recovery is implemented, then automation is achieved, but it does not support passive site with reduced virtual machines
Solution Approach 1:
The system dynamically adapts its behavior based on the operational mode. The site recovery manager modules can automatically configure and execute recovery plans for passive sites with reduced virtual machines, while maintaining the capability to handle active-active scenarios. The cloud orchestrator processes disaster recovery configuration requests to update site recovery manager modules, enabling flexible adaptation between different disaster recovery modes without requiring system redesign.
3Reliability
If replication module replicates storage resources, then disaster recovery capability is enabled, but system complexity increases
Solution Approach 1:
The cloud orchestrator serves multiple functions: it acts as a centralized controller for disaster recovery operations, communicates with both sites through the public cloud, processes disaster recovery configuration requests, updates site recovery manager modules, and coordinates replication operations. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while enabling comprehensive disaster recovery protection across both active and passive sites.
