A company is optimizing its e-commerce platform to improve user experience by reducing page load times and increasing responsiveness. According to the AWS Well-Architected Framework, which of the following actions is a key principle of the Performance Efficiency pillar?
Architecting the platform to automatically recover from component failures.
Deploying the platform in AWS Regions physically closer to the largest user bases.
Using Spot Instances and Reserved Instances to reduce compute costs.
Implementing automated scaling to match capacity with traffic demand.
The correct answer aligns with a key design principle of the Performance Efficiency pillar: to reduce latency for a global user base by deploying resources in multiple AWS Regions. Placing infrastructure closer to end-users directly improves responsiveness. Automated scaling is a valid practice but serves both Performance Efficiency and Cost Optimization by matching capacity to demand. Using Spot and Reserved Instances is a primary strategy for the Cost Optimization pillar. Architecting for automatic recovery is a core concept of the Reliability pillar.
