Choose the key pair we made from the drop down list.

In the above screen there is other customization that you can make. If you want over-the-wire encryption (uses IPsec), then set the option "Enable Encryption" to "True".

You can pre-populate your cluster with data from an S3 bucket. Use the "ImportBucket" field to specify your bucket, "ImportDest" for where you want the data in the Lustre Filesystem and "importPrefix" to specify a starting point in your bucket.

The "MdsInstanceType" and" OssInstanceType" are used to change the type of storage that the MDS and all OSS servers will use.

The OSSCount is to change the default of 4 OSS servers to what you need.

"OssVolumeCount" and "OstVolumeSize" are to change the number and size of EBS volumes used for an OST.

In the screenshot below is the "WorkerCount" and "WorkerInstanceType" to specify the number of client nodes you would like created and the type of VM instance to use. You would not need these if you have your own clients configured separately that you want to connect to this filesystem.

To continue with this example in Choose the VPC we created in the "Vpcid" drop-down box.

Fill out the CIDR and choose the subnet we created when we created our VPC.

...

go to the next screen and click on "Next". No changes will be made on this screen.

check the box.. yes we know AWS is not free. And then click on "Create"

When you go to this the GUI transitions to the next page, you may need to refresh using the refresh symbol the upper right of the page.

You can return to this page any time by clicking on "Cloud Formation" that we put on the access bar.

...

To access the servers, you will need to ssh to the NAT node with a pagent active and forwarding enabled and then ssh from here the NAT node to the servers.

For windows, start "pagent" and add you your private key. Then when you use putty, go to the ssh auth page under ssh and check the box to "allow agent forwarding". In Putty also remember to point to your private key in the auth section.

Once you are SSHed to the NAT node, you can ssh to the servers, again as "ec2-user". sudo will work from this ec2-user.

To get the IP addresses of the servers or clients that were created, click on "EC2"  from the access bar and click on "instances" in the left hand pane and then select the server.

Here the MGS is shown. In the bottom pane the IP address of the MGS is shown at the top. You can also get IP addresses for the servers from the dashboard->cluster page.

You can also get the IP address to access your clients, mount the filesystem and have some Lustre fun on AWS.
