Zorluk: OrtaAWS Global Infrastructure

A financial services startup is designing a secure payment transaction processing system. To protect against local site failures such as power outages or flooding at a single facility, they want to distribute their application servers across multiple physical data centers. However, all data must remain within the same geographic boundary for compliance, and the replication latency must be minimal. Which AWS infrastructure design should the startup implement to satisfy these requirements?

  2. B
    Deploy the application across multiple AWS Regions.
  3. C
    Deploy the application using AWS Edge Locations.
  4. D
    Deploy the application using AWS Outposts in multiple on-premises data centers.

Cevap

Deploy the application across multiple Availability Zones within a single AWS Region.
Deploying the application across multiple Availability Zones in a single AWS Region is the correct design. Availability Zones are physically distinct groups of data centers within a Region. They are isolated from local hazards like flooding or power grid failures, yet connected by low-latency networking. This allows for synchronous data replication and high availability while keeping all data residency within the same region.

Adım Adım Çözüm

1
Analyze the requirements: protection against local site failures (multi-facility/data center redundancy), minimal latency, and compliance requiring data to remain within the same geographic boundary.
Identify that the solution must utilize separate physical facilities located close enough to maintain low latency and within the same regulatory boundary.
This narrows down the choice between Regions, Availability Zones, Edge Locations, and Outposts.
2
Evaluate the architectural roles of AWS Global Infrastructure components.
Determine that Availability Zones (AZs) consist of isolated data centers within a single Region, providing low-latency replication and fault isolation while keeping data local. AWS Regions are too geographically dispersed and increase latency/sovereignty issues. Edge Locations are for content delivery caching. Outposts is for hybrid cloud, not cloud-native multi-facility redundancy.
This selects the single best component designed for high availability within a region.
