A
Amazon EBS volume
B
Amazon S3
C
Amazon EC2 instance store
D
Amazon RDS instance
Explanation:
Amazon S3 is the correct choice because:
- Durable storage: S3 provides 99.999999999% (11 nines) durability for objects stored
- Static content optimization: S3 is specifically designed for storing and serving static content like images, videos, CSS, JavaScript files
- Lower CPU utilization: By offloading static content to S3, the web tier EC2 instances don't need to handle file serving, reducing CPU load
- Cost-effective: S3 is more cost-effective for static storage compared to EBS volumes
- High availability: S3 is highly available across multiple Availability Zones
Amazon EBS volumes are block storage attached to EC2 instances, EC2 instance store is ephemeral storage, and Amazon RDS is for databases - none are optimized for static content serving like S3.
