I played with AWS a bit, more than play with AWS, I used AWS to play with LVM stripping.

[root@ip-172-31-13-194 ~]# lvcreate -i20 -L 10G vg00
  Using default stripesize 64.00 KiB.
  Logical volume "lvol0" created.

[root@ip-172-31-13-194 ~]# lvcreate  -L 10G vg00
  Logical volume "lvol1" created.

Clearly stripping improves the performance :)

To create the volumes I used this simple scripts

$ cat ~/bin/iterations
#!/bin/bash
iterations=$1
shift
for ((i=1;i<=$iterations;i++));
do
        $@
done

$ iterations 10 aws ec2 create-volume --availability-zone ap-northeast-1c --size 1

To attach the volumes I used this for loop

$ for i in a b c d e f g h i j k l m n o p q r s t u v w x y z ; do aws ec2 attach-volume --volume-id `aws ec2 describe-volumes --max-items 1 --filters "Name=status,Values=available" |jq .Volumes |grep VolumeId |cut -c 18-29` --instance-id i-b77a3938 --device "/dev/xvd$i" ; done

and repeat with devices xvda$i, xvdb$i, etc.
