Google Cloud Digital LeaderDigital transformation with Google CloudEasy
A global technology company is implementing a robust disaster recovery strategy for its critical applications and data on Google Cloud. They need to ensure that their services remain available even in the event of a regional outage. This involves deploying applications and storing data across multiple geographically separate locations, with automatic failover capabilities. Which Google Cloud infrastructure concept is fundamental to achieving this level of resilience?
- ACloud CDN
- BCloud VPN
- CCloud Logging
- DGoogle Cloud Regions and Zones
Show answer & explanationAnswer & explanation
Correct answer: D. Google Cloud Regions and Zones
Google Cloud's global infrastructure is organized into regions and zones. Deploying applications and data across multiple regions (for regional outages) and multiple zones within a region (for zonal outages) is fundamental to building highly available and resilient systems that can withstand failures and enable disaster recovery.
Why the other options are wrong
- A. Cloud CDN caches content at edge locations, improving performance but not directly providing a disaster recovery solution for core application infrastructure.
- B. Cloud VPN provides network connectivity, but doesn't define the physical locations for disaster recovery.
- C. Cloud Logging is for collecting and analyzing logs, not for defining infrastructure for disaster recovery.
Google Cloud Regions and Zones
Google Cloud's global infrastructure is divided into geographical regions, each containing multiple isolated locations called zones.
- Regions are independent geographic areas
- Zones are isolated locations within a region
- Deploying across multiple zones/regions provides high availability and disaster recovery
Memory trick: Regions and Zones are like 'rooms' and 'buildings' in a global city.
