A global manufacturing company with operations in multiple countries is evaluating a cloud provider for its new enterprise resource planning (ERP) system. The company requires consistent application performance and data residency compliance across its global offices. The cloud provider offers 'Regions' and 'Availability Zones'. To meet the global performance and compliance requirements, which strategy should the company prioritize when deploying its ERP system?
- ADeploy the ERP system across multiple Regions, ensuring a Region is selected for each country with specific data residency compliance.
- BUtilize multiple Availability Zones within a single relevant Region for high availability and disaster recovery.
- CDeploy the ERP system in a single Availability Zone within a central Region to simplify management.
- DLeverage Edge Locations and Content Delivery Networks (CDNs) exclusively to improve performance for all global users.
Show answer & explanationAnswer & explanation
Correct answer: A. Deploy the ERP system across multiple Regions, ensuring a Region is selected for each country with specific data residency compliance.
Deploying across multiple Regions is crucial for global performance and data residency compliance. Each Region is a distinct geographic area, allowing the company to deploy its ERP system closer to users in different countries for consistent performance and to ensure data is stored within the boundaries of specific countries to meet data residency regulations.
Why the other options are wrong
- B. Multiple AZs within a single Region provide high availability within that Region but do not address global performance or data residency across multiple countries.
- C. A single AZ in a central Region would not address global performance or data residency requirements.
- D. Edge Locations and CDNs are for caching content and improving delivery, not for hosting the primary ERP application itself or ensuring data residency for core data.
Cloud Global Reach (Regions)
The capability of cloud providers to offer services across geographically dispersed data centers (Regions) to meet requirements for data residency, low latency, and disaster recovery.
- Regions are distinct geographic areas
- Critical for data residency compliance
- Ensures low latency for global users
Memory trick: For global success, think 'R' for Regions for Residency and Reach, not just local 'A' for AZ Availability.
