A global technology company is planning to deploy a new highly available and fault-tolerant application on Google Cloud. They need to ensure that their application can withstand the failure of an entire data center. Which Google Cloud infrastructure component should they leverage to achieve this requirement?
- AGoogle Cloud Zones
- BGoogle Cloud Regions
- CGoogle Cloud Projects
- DGoogle Cloud Networks
Show answer & explanationAnswer & explanation
Correct answer: B. Google Cloud Regions
To withstand the failure of an entire data center, applications must be deployed across multiple independent data centers, which Google Cloud defines as Regions. Zones are locations within a Region and are not isolated enough for this requirement.
Why the other options are wrong
- A. Google Cloud Zones represent distinct locations within a Region and can fail independently, but a Region contains multiple Zones and offers broader isolation.
- C. Google Cloud Projects are organizational containers for resources and do not directly provide infrastructure for fault tolerance.
- D. Google Cloud Networks facilitate communication between resources but do not inherently provide the physical isolation required to withstand data center failures.
Google Cloud Regions
Google Cloud Regions are independent geographic areas that contain multiple Zones, designed for high availability and disaster recovery.
- Each Region is a collection of physically isolated data centers (Zones).
- Provides fault tolerance against an entire data center failure.
- Offers low-latency access to users within its geographic area.
Memory trick: Regions are like continents, holding many Zones like cities, ensuring global reach and resilience.
