A sovereign wealth fund based in Singapore is migrating its core financial reporting platform to AWS. To comply with national data sovereignty laws, all financial records must reside physically within Singapore. Additionally, the platform must be highly available and resilient against localized power grid or cooling failures. Which of the following infrastructure designs satisfies these requirements?

  1. Deploy the application across multiple Availability Zones within the Singapore Region.Cevap
  2. B
    Deploy the application across multiple AWS Regions within Southeast Asia to distribute the workload.
  3. C
    Deploy the application in a single Availability Zone and replicate data to Edge Locations situated throughout Asia.
  4. D
    Deploy the application across multiple data centers inside a single Availability Zone to ensure physical isolation.

Cevap

Deploy the application across multiple Availability Zones within the Singapore Region.
The correct architecture uses multiple Availability Zones within the Singapore Region. This keeps the data within the national boundary of Singapore to satisfy compliance laws, while leveraging the physical separation, independent power, and cooling of multiple Availability Zones to ensure high availability and disaster resilience.

Adım Adım Çözüm

1
Analyze the business requirements for data residency and physical isolation.
The application must keep all data physically inside Singapore and must survive a localized power or cooling failure at a facility.
This establishes constraints: the data must remain in the Singapore Region, and the deployment must span multiple isolated infrastructure boundaries.
2
Map these constraints to AWS Global Infrastructure components.
An AWS Region provides a defined geographic boundary (Singapore), while Availability Zones (AZs) within that Region provide isolated locations with redundant power, networking, and connectivity.
Using multiple AZs in the Singapore Region ensures that if one AZ suffers a facility outage, the application remains operational in another AZ, all while keeping the data within Singapore's physical borders.

Anahtar Kavram

AWS Regions provide data sovereignty and residency boundaries, while Availability Zones provide fault isolation and high availability within a Region.
