Difficulty: EasyAWS Global Infrastructure

An e-commerce company is hosting its website on AWS. The company wants to reduce the latency for global website visitors downloading static files, such as image headers and stylesheets, which are stored in a central AWS Region. Which AWS Global Infrastructure component is designed to cache this content closer to users globally?

  1. Edge LocationsAnswer
  2. B
    Availability Zones
  3. C
    AWS Regions
  4. D
    Auto Scaling groups

Answer

Edge Locations
The option specifying Edge Locations is correct because Edge Locations cache static and dynamic web content closer to users worldwide via Amazon CloudFront (AWS's Content Delivery Network), reducing latency and improving loading times.

Step-by-Step Solution

1
Analyze the primary requirement of the scenario.
The requirement is to reduce the download latency of static assets for users distributed globally.
Identifying the target goal helps differentiate between high-availability solutions and caching solutions.
2
Evaluate the AWS Global Infrastructure components designed for caching.
AWS Edge Locations host cache nodes for Amazon CloudFront, delivering static content from locations physically closer to the users.
This contrasts with Regions and Availability Zones, which host the core infrastructure resources rather than distributing cached assets.

Key Concept

AWS Global Infrastructure components and their roles in content delivery and latency optimization.
