A gaming company uses AWS Compute Optimizer recommendations to select optimal EC2 instance types and experiments with serverless architectures to reduce latency and improve resource utilization for its workloads. Which Well-Architected Framework pillar does this scenario primarily address?
- AOperational Excellence
- BReliability
- CPerformance Efficiency
- DCost Optimization
Show answer & explanationAnswer & explanation
Correct answer: C. Performance Efficiency
The Performance Efficiency pillar focuses on using computing resources efficiently to meet system requirements and maintaining that efficiency as demand changes and technologies evolve, including selecting appropriate resource types and experimenting with new approaches.
Why the other options are wrong
- A. Operational Excellence is about running/monitoring systems, not resource selection for performance.
- B. Reliability is about failure recovery, not efficiency.
- D. Cost Optimization is about spend reduction, not efficiency of resource usage per se.
Performance Efficiency Pillar
A Well-Architected pillar focused on using IT and computing resources efficiently and adapting as needs and technology evolve.
- Includes selecting right resource types
- Encourages experimentation with new services
- Considers tradeoffs like latency vs cost
Memory trick: Performance = Pick the right tool for the job.
