Zorluk: ZorAWS Global Infrastructure

A company is building a global video streaming platform. The architecture requires that the backend transcoding compute servers be highly available and resilient to the failure of an entire physical data center facility. At the same time, the static video files must be cached globally to minimize delivery latency for viewers worldwide. Which combination of AWS infrastructure components best satisfies these design requirements?

  1. Deploy the transcoding compute servers across multiple Availability Zones in a single AWS Region, and use AWS Edge Locations to cache the video files globally.Cevap
  2. B
    Deploy the transcoding compute servers in a single Availability Zone, and configure AWS Edge Locations to host the backup standby servers for automatic failover.
  3. C
    Deploy the transcoding compute servers across multiple AWS Regions to protect against local data center outages, and use different Availability Zones to cache and deliver the video files to global users.
  4. D
    Deploy the transcoding compute servers in a single AWS Local Zone, and use AWS Wavelength Zones to cache the video files at the edge of the internet for global users.

Cevap

Deploy the transcoding compute servers across multiple Availability Zones in a single AWS Region, and use AWS Edge Locations to cache the video files globally.
Deploying the transcoding compute servers across multiple Availability Zones in a single AWS Region provides high availability and fault isolation for the compute layer, as each Availability Zone is physically separated and has redundant power, networking, and connectivity. Using AWS Edge Locations to cache video files globally minimizes latency for viewers by serving the cached content from the nearest geographic location.

Adım Adım Çözüm

1
Analyze the high availability requirement for the compute layer.
Determine that surviving a physical data center facility outage within a geographic area is achieved by deploying across multiple Availability Zones (AZs) in a single Region, since AZs are physically separated and isolated from one another.
AWS Regions contain multiple, isolated Availability Zones designed to provide fault isolation for running workloads.
2
Analyze the low-latency global content delivery requirement.
Determine that global content caching and delivery requires utilizing AWS Edge Locations, which are distributed globally to cache content closer to end-users.
Edge Locations run Amazon CloudFront to cache static files, reducing latency for global viewers.
3
Combine the infrastructure components to find the correct architecture.
Deploy the transcoding compute servers across multiple Availability Zones in a single AWS Region, and use AWS Edge Locations to cache the video files globally.
This matches the correct use cases for Regions, Availability Zones, and Edge Locations, avoiding structural misconceptions.
