Zorluk: OrtaAWS Global Infrastructure

A global media network is migrating its digital publishing platform to AWS. The network needs to ensure that its primary publishing database is resilient against localized disasters, such as power grid failures or flooding, within its main operating market. Additionally, the network must deliver static image and video assets to a worldwide audience with minimal delay. Which of the following AWS Global Infrastructure design decisions will meet these requirements? (Select TWO).

  1. Deploying the primary database across multiple Availability Zones within a single AWS RegionCevap
  2. Utilizing AWS Edge Locations to cache and serve static media assets globallyCevap
  3. C
    Hosting the primary database directly within AWS Edge Locations to achieve high availability
  4. D
    Replicating the database synchronously across multiple AWS Regions to guard against local power outages
  5. E
    Deploying the database in a single Availability Zone and configuring Amazon Route 53 to host database replicas

Cevap

Deploying the primary database across multiple Availability Zones within a single AWS Region, and utilizing AWS Edge Locations to cache and serve static media assets globally.
Deploying the primary database across multiple Availability Zones within a single AWS Region ensures high availability and resilience because each Availability Zone is physically isolated with independent infrastructure (power, cooling, network). Utilizing AWS Edge Locations to cache and serve static media assets globally reduces latency for international viewers by serving files from locations closer to them.

Adım Adım Çözüm

1
Analyze the high-availability requirement for the database.
Identify that protecting against localized disasters (power failures, flooding) within a market requires deploying resources across physically separated locations within the same region (Availability Zones).
Availability Zones are isolated locations within a geographic AWS Region that are connected through low-latency links but are on separate power and flood plains.
2
Analyze the low-latency content delivery requirement.
Identify that serving static images and videos to a worldwide audience with minimal delay requires caching content close to the users.
AWS Edge Locations cache content close to global end-users, reducing latency for static assets.
