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

A media company is developing a new video-on-demand (VOD) platform. They need a storage solution for their extensive library of high-resolution video files that must be immediately accessible for streaming. The solution must offer high throughput, low latency, and be highly available across multiple Availability Zones. Cost optimization is also a key consideration, but performance cannot be sacrificed.

  1. AAmazon S3 Standard-IA
  2. BAmazon EBS gp2 volumes attached to EC2 instances
  3. CAmazon S3 Standard
  4. DAmazon S3 Glacier Flexible Retrieval
Show answer & explanation

Correct answer: C. Amazon S3 Standard

Amazon S3 Standard is designed for frequently accessed data, offering high durability, availability, and performance suitable for VOD content. Its immediate accessibility and scalability align with the requirements, making it a cost-effective choice for active streaming data compared to other S3 tiers or EBS for this scale.

Why the other options are wrong

  • A. S3 Standard-IA is for infrequently accessed data and incurs retrieval fees, which is not ideal for immediate streaming.
  • B. While EBS gp2 can offer performance, managing it for petabytes of VOD content across multiple AZs would be complex and significantly more expensive than S3.
  • D. S3 Glacier Flexible Retrieval is for archival data with retrieval times ranging from minutes to hours, unsuitable for VOD.

  • High availability (99.99%)
  • Low latency and high throughput
  • Suitable for a wide range of use cases including cloud applications, dynamic websites, content distribution, and big data analytics.

Memory trick: Standard for Streaming, IA for Infrequent, Glacier for Gone.
