Question
A company wants to use Amazon EC2 instances to provide a static website to users all over the world. The company needs to minimize latency for the users. Which solution meets these requirements?
Options
- AUse Amazon ElastiCache as the database for the EC2 instances.
- BUse EC2 instances in the same edge location and the same Availability Zone.
- CUse Amazon CloudFront with the EC2 instances configured as the source.
- DUse EC2 instances in the same Availability Zone but in different AWS accounts.
Explanation
Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations worldwide, reducing latency for users accessing static websites hosted on EC2 instances. ElastiCache is for in-memory caching, not static website delivery. Edge locations are used by CloudFront, not for running EC2 instances. EC2 is not deployed directly in edge locations. Using different AWS accounts does not impact latency or improve global performance.
