    Hi Victor,

    You have a valid point regarding the current architecture in the scenario. Storing data to the EBS volumes of the instances that are in an Auto Scaling group is not efficient. The data access is not centralized and it is difficult to determine which EBS volume has a specific file.


    S3 is not POSIX-compliant and EBS is not suitable to be used as a shared and high-throughput storage file system that will be accessed by multiple EC2 instances.


    The only storage type that can meet this requirement is EFS.

    Cheers,
