A fleet of CMS instances behind an Auto Scaling group must read and write a common content folder. Which storage service fits that shared file access pattern?
Select an answer to reveal the explanation.
Short Explanation
EFS is the shared city filing cabinet every CMS desk can open at once. Private EBS disks, glacier vaults, and throwaway instance store aren’t a common live content folder.
Full Explanation
Amazon EFS provides a shared NFS file system that multiple EC2 instances can mount concurrently, which fits CMS content directories across an Auto Scaling group. Non-shared EBS, Glacier archives, and ephemeral instance store do not provide durable shared POSIX file access for a scaled web tier.
