A public-works EC2 instance needs a persistent block-storage volume for its operating system and application data disks. Which AWS service provides that attachable block storage?
Select an answer to reveal the explanation.
Short Explanation
EC2 needs a real disk personality for the OS—block storage you can attach and persist. That is Amazon EBS: volumes that behave like drives for your instances. S3 buckets are fantastic for objects, but they are not the boot-and-data volumes your virtual server mounts.
Full Explanation
Amazon EBS provides persistent block-level volumes that attach to Amazon EC2 instances for boot and data disks. That model matches virtual machine storage needs where the operating system and applications expect a block device. S3 is object storage; CloudFront and Athena address content delivery and querying, not EC2 volume attachment.
