Google Cloud Digital LeaderDigital transformation with Google CloudHard
A global technology company is implementing a robust disaster recovery strategy for its critical applications hosted on Google Cloud. They need to ensure that their applications can fail over to a different region with minimal downtime (low RTO) and minimal data loss (low RPO) in the event of a regional outage. Which Google Cloud capability is most crucial for achieving these disaster recovery objectives?
- ACompute Engine custom machine images.
- BCloud IoT Core for device connectivity.
- CGlobal network infrastructure and multi-region deployments.
- DCloud Storage Nearline for cost-effective archiving.
Show answer & explanationAnswer & explanation
Correct answer: C. Global network infrastructure and multi-region deployments.
Google Cloud's global network infrastructure and the ability to deploy applications across multiple regions are fundamental for achieving low RTO and RPO in disaster recovery, as they enable rapid failover and data replication across geographically dispersed locations.
Why the other options are wrong
- A. Custom machine images are useful for consistent deployments but don't inherently provide multi-region failover capabilities for disaster recovery.
- B. Cloud IoT Core is for connecting IoT devices, which is unrelated to application disaster recovery.
- D. Cloud Storage Nearline is for archival storage, not for active disaster recovery of critical applications requiring low RTO/RPO.
Google Cloud Global Infrastructure
Google Cloud's global network of data centers, regions, and zones, connected by a high-performance fiber network, designed for high availability, low latency, and disaster recovery.
- Regions are independent geographic areas, zones are distinct locations within regions.
- Enables multi-region deployments for fault tolerance and disaster recovery.
- Facilitates global load balancing and data replication.
- Underpins services like Cloud Spanner, global load balancers.
