A financial services company is developing a new trading application that requires extremely low latency and high transaction throughput. They are evaluating the AWS Well-Architected Framework to guide their design. Which pillar should be their primary focus to ensure the application meets these performance requirements?
- ACost Optimization
- BOperational Excellence
- CSecurity
- DPerformance Efficiency
Show answer & explanationAnswer & explanation
Correct answer: D. Performance Efficiency
The Performance Efficiency pillar focuses on using computing resources efficiently to meet system requirements and maintain that efficiency as demand changes. This directly addresses the need for low latency and high transaction throughput.
Why the other options are wrong
- A. The Cost Optimization pillar focuses on achieving business value at the lowest price, which is separate from meeting strict performance requirements.
- B. The Operational Excellence pillar focuses on running and monitoring systems effectively, not directly on raw performance metrics.
- C. The Security pillar focuses on protecting data and systems, not primarily on latency or throughput.
Performance Efficiency Pillar
The ability to use computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes and technologies evolve.
- Focuses on resource efficiency.
- Addresses latency and throughput.
- Adapts to demand changes.
