Multi-Cloud Disaster Recovery across AWS, Azure, and GCP
Table of Contents
Mitigating Single Cloud Vendor Concentration Risk
While major public cloud providers boast high uptime SLA percentages, global cloud region outages still occur. Relying on a single cloud provider creates single-point-of-failure vulnerabilities for mission-critical apps.
Designing Cross-Cloud Data Replication Pipelines
Multi-Cloud DR establishes continuous database replication between AWS Aurora/RDS and Azure SQL or GCP Cloud Spanner, maintaining standby application instances ready to receive traffic instantly.
Automated Cross-Cloud DNS Failover Routing
Global Traffic Managers (GTM) perform health check probes every 10 seconds. In the event of a primary AWS cloud region failure, DNS traffic routes automatically to the secondary Azure environment.
