Google Cloud Digital LeaderDigital transformation with Google CloudMedium
A traditional financial institution is undergoing a digital transformation to modernize its core banking systems. They need to ensure strict regulatory compliance, including data residency requirements, and maintain extremely low-latency access to customer transaction data for real-time fraud detection and personalized customer experiences. The solution must provide high availability and disaster recovery across multiple locations within a specific geographical region. Which Google Cloud deployment strategy would best address these concerns?
- AUsing on-premises infrastructure with direct peering to Google Cloud.
- BDeploying resources across multiple regions globally for maximum distribution.
- CDeploying resources across multiple zones within a single region.
- DDeploying all resources in a single zone within one region.
Show answer & explanationAnswer & explanation
Correct answer: C. Deploying resources across multiple zones within a single region.
Deploying resources across multiple zones within a single region ensures high availability and disaster recovery by distributing workloads across isolated failure domains, while strictly adhering to data residency requirements within that specific geographical region. This balances resilience with compliance and low latency.
Why the other options are wrong
- A. While direct peering can improve connectivity, it doesn't inherently provide the cloud-native high availability and disaster recovery benefits across zones within a region.
- B. Multiple global regions would violate data residency requirements if data crosses geographical boundaries.
- D. A single zone deployment lacks high availability and disaster recovery in case of a zone-wide outage.
Google Cloud Regions and Zones
Google Cloud services are deployed in geographical regions, which are further divided into zones. Regions offer geographic isolation, while zones within a region provide high availability and fault tolerance.
- Regions are independent geographic areas.
- Zones are isolated locations within a region.
- Multi-zone deployments offer high availability within a region.
Memory trick: Zones keep data safe and near, regions keep it clear.
