Q. How do I access a file system from
an Amazon EC2 instance?
To access your file system, you mount
the file system on an Amazon EC2 Linux-based instance using the standard Linux
mount command and the file system’s DNS name. Once you’ve mounted, you can work
with the files and directories in your file system just like you would with a
local file system.
Amazon EFS uses the NFSv4.1 protocol.
For a step-by-step example of how to access a file system from an Amazon EC2
instance, please see the Amazon EFS Getting Started guide.
Q. What Amazon EC2 instance types and
AMIs work with Amazon EFS?
Amazon EFS is compatible with all
Amazon EC2 instance types and is accessible from Linux-based AMIs. You can mix
and match the instance types connected to a single file system. For a
step-by-step example of how to access a file system from an Amazon EC2
instance, please see the Amazon EFS Getting Started guide.
Q. How do I load data into a file
system?
You can load data into an Amazon EFS
file system from your Amazon EC2 instances or from your on-premises datacenter
servers.
Amazon EFS file systems can be
mounted on an Amazon EC2 instance, so any data that is accessible to an Amazon
EC2 instance can also be read and written to Amazon EFS. To load data that is
not currently stored on the Amazon cloud, you can use the same methods you use
to transfer files to Amazon EC2 today, such as Secure Copy (SCP).
Amazon EFS file systems can also be
mounted on an on-premises server, so any data that is accessible to an
on-premises server can be read and written to Amazon EFS using standard Linux
tools. For more information about accessing a file system from an on-premises
server, please see the On-premises
Access section of
the Amazon EFS FAQ.
For more information about moving
data to the Amazon cloud, please see the Cloud
Data Migration page.
Q. How do I access my file system
from outside my VPC?
Amazon EC2 instances within your VPC
can access your file system directly, and Amazon EC2 Classic instances outside
your VPC can mount a file system via ClassicLink. On-premises servers can mount your file
systems via an AWS
Direct Connect connection
to your VPC.
Q. How many Amazon EC2 instances can
connect to a file system?
Amazon EFS supports one to thousands
of Amazon EC2 instances connecting to a file system concurrently.
Q: Where can I learn more about EFS?
It is really a great work and the way in which you are sharing the knowledge is excellent.
