I have created an Amazon EFS filesystem in the Sydney Region and would like to mount it on an EC2 instance in the Singapore region.
Is this possible?
This answer is outdated. Please see other answer.
An Amazon EFS filesystem is only accessible in the VPC that was selected when it was created, or via Direct Connect when linked to that VPC.
Each Amazon VPC is only in one Region.
As per the Amazon EFS Limits documentation page:
An Amazon EFS file system can be mounted from on-premises datacenter servers using AWS Direct Connect. However, other VPC private connectivity mechanisms such as a VPN connection and VPC peering are not supported.
