AWS Certified Solutions Architect – Associate (SAA-C03)Design Resilient ArchitecturesEasy

A global e-commerce company is experiencing intermittent performance issues with its web application during peak traffic. The application is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB). Users report slow page loads and occasional timeouts. The company wants to improve the responsiveness and availability of the application without significantly re-architecting the existing setup. Which AWS service should be implemented to address these performance and availability concerns?

  1. AAWS Direct Connect to establish a dedicated network connection.
  2. BAmazon CloudFront with caching enabled for static and dynamic content.
  3. CAWS Storage Gateway to provide on-premises access to cloud storage.
  4. DAmazon WorkSpaces to provide virtual desktops for users.
Show answer & explanation

Correct answer: B. Amazon CloudFront with caching enabled for static and dynamic content.

Amazon CloudFront is a content delivery network (CDN) service that can drastically improve web application performance by caching content closer to users and offloading requests from origin servers. This reduces latency and improves availability during peak traffic.

Why the other options are wrong

  • A. AWS Direct Connect improves connectivity between on-premises and AWS, not user-facing application performance for a global web app.
  • C. AWS Storage Gateway is for hybrid cloud storage solutions, not for accelerating web application delivery to end-users.
  • D. Amazon WorkSpaces provides virtual desktops, which is unrelated to improving web application performance or availability.

Amazon CloudFront

A fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds.

  • Uses a global network of edge locations (Points of Presence).
  • Caches content to reduce origin server load and improve user experience.
  • Supports both static and dynamic content delivery.

Memory trick: CloudFront brings your content right to their front door, fast!
