Difficulty: MediumAWS Global Infrastructure

An e-learning platform hosting its application in the us-east-1 Region wants to ensure its static study materials are delivered with the lowest possible latency to students worldwide. Additionally, the platform's web servers must survive the failure of a single data center facility within us-east-1. Which combination of AWS global infrastructure components should the platform utilize to meet these requirements?

  1. AWS Edge Locations to cache static content globally, and multiple Availability Zones to deploy redundant web servers.Answer
  2. B
    Multiple AWS Regions to cache static content globally, and a single Availability Zone with multiple Edge Locations to host the web servers.
  3. C
    Multiple Availability Zones to cache static content globally, and multiple Edge Locations to host the web servers.
  4. D
    AWS Outposts to cache static content globally, and AWS Local Zones to run the web servers.

Answer

AWS Edge Locations to cache static content globally, and multiple Availability Zones to deploy redundant web servers.
The correct option correctly identifies the distinct roles of AWS Edge Locations and Availability Zones. AWS Edge Locations are distributed globally to cache content close to users, minimizing latency. Availability Zones are isolated locations within an AWS Region consisting of one or more physical data centers, providing high availability and fault tolerance against facility-level outages when applications are deployed across them.

Step-by-Step Solution

1
Analyze the global content delivery requirement.
AWS Edge Locations cache content close to end-users worldwide, reducing latency for static assets.
To deliver content to a global audience with the lowest latency, caching must happen close to the users rather than fetching from the origin Region every time.
2
Analyze the web server fault tolerance requirement within the US East (N. Virginia) Region (us-east-1).
Availability Zones consist of one or more discrete, isolated data center facilities with redundant power, networking, and connectivity.
Distributing web servers across multiple Availability Zones within the same Region ensures that if one physical data center facility fails, the application remains online via the remaining Availability Zones.
3
Combine both infrastructure requirements.
The platform should use AWS Edge Locations for the global content caching layer and multiple Availability Zones for the regional hosting layer.
This separation of concerns utilizes the global network of Edge Locations for delivery speed and regional Availability Zones for operational resilience.
