A Developer is migrating an on-premises application to AWS. The application currently takes user uploads and saves them to a local directory on the server. All uploads must be saved and made immediately available to all instances in an Auto Scaling group.
Which approach will meet these requirements?
- A. Use Amazon EBS and configure the application AMI to use a snapshot of the same EBS instance on boot.
- B. Use Amazon S3 and rearchitect the application so all uploads are placed in S3.
- C. Use instance storage and share it between instances launched from the same Amazon Machine Image (AMI).
- D. Use Amazon EBS and file synchronization software to achieve eventual consistency among the Auto Scaling group.
