CompTIA Cloud Essentials+ (CLO-002)Business Principles of Cloud EnvironmentsMedium
A global e-commerce company is experiencing rapid growth and needs to ensure its customer-facing application is highly available and responsive to users worldwide. They want to minimize latency and provide disaster recovery capabilities across different geographical locations. Which cloud concept is MOST critical for achieving these goals?
- ACloud Regions and Availability Zones
- BServerless Computing
- CContent Delivery Network (CDN)
- DVirtual Private Cloud (VPC)
Show answer & explanationAnswer & explanation
Correct answer: A. Cloud Regions and Availability Zones
Cloud Regions allow for deploying applications closer to global users to minimize latency, while Availability Zones within a region provide isolation for high availability and disaster recovery, addressing all stated requirements.
Why the other options are wrong
- B. Serverless computing is an execution model, not a concept for geographical distribution and disaster recovery.
- C. CDN helps with content delivery latency but doesn't provide the underlying infrastructure for application deployment, high availability, or comprehensive disaster recovery across regions.
- D. VPC provides network isolation but doesn't inherently address global reach, latency, or disaster recovery across geographies.
Cloud Regions and Availability Zones
Geographically distinct locations (Regions) hosting multiple isolated data centers (Availability Zones) to provide global reach, high availability, and disaster recovery for cloud services.
- Regions offer geographic proximity for low latency.
- Availability Zones provide fault isolation within a region.
- Crucial for high availability, disaster recovery, and compliance.
Memory trick: Regions are big lands, Zones are safe sands.
