What happens if Server 1 creates a file in EFS? Can Server 2 access it?
Yes, Server 2 can access it immediately.
Amazon EFS provides a shared file system. When Server 1 creates a file, it is saved directly to the cloud network, allowing any other connected server to view or modify it right away.

Does EFS storage capacity need to be specified in advance?
No, you do not need to specify EFS storage capacity in advance.
