CentOS 6 (x86_64) - with Updates HVM
CentOS.org | 2002_01Linux/Unix, CentOS 6 - 64-bit Amazon Machine Image (AMI)
Clean and with cloud-init support
I was struggling getting a shell script in EC2 user-data to work, when I realized I was using deprecated official CentOS AMIs that was lacking cloud-init support. I upgraded to this one (thanks to the official documentation: https://wiki.centos.org/Cloud/AWS) and I'm happy to see it is already included.
So, OK, maybe root ssh login is disabled, but nothing prevents you from getting it back using a small user-data script:
#!/bin/bash
sed -i -e 's/^.*\(ssh.*$\)/\1/' /root/.ssh/authorized_keys

No surprises
I wanted CentOS 6, and that is exactly what I got. No tricks, nothing special, just CentOS 6. It comes up as CentOS 6.5, which you can update to 6.6 in a couple of minutes (and then snapshot). I just used it as a way of testing Drupal 7 before running it locally. Easy.
CentOS
CentOS let's me run the apps I need without surprises. I've tried other distros but keep coming back to CentOS. It works as advertised.
Very good to use

Volume resize procedure
Here is the gist to resize your disk after selecting a larger than 8GB volume:
fdisk /dev/xvda
u #Change the display to sectors
p #Print info
d #Delete the partition
n #New partition
p #Primary partition
1 #Partition number
2048 #First sector
Press Enter to accept the default
p #Print info
a #Toggle the bootable flag
1 #Select partition 1
w #Write table to disk and exit
reboot
After it comes back do:
resize2fs /dev/xvda1
verify the new disk size:
df -h
Regarding Default Partition Resizing
Yes, this AMI is configured with LVM. Meaning scaling and resizing the partition is different than just using the resize2fs command. However, this can be learned:
https://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/index.html
You have to learn how LVM works to learn how to resize it.
However, there does seem to be great advantage in this as you can keep adding volumes and expanding the LVMs as desired with the same logical volume. Seems very scale-able.
Good luck!
BTW, this may be the best CentOS 6 image for my needs, so learning it was necessary.
As for Additional IP addressing on the same Network Interface this greatly helped me out:

Great machine for a server
This machine worked very well for me. I set it up to run Oracle database and applications and it presented no difficulties. Yum package management is great.
Being HVM, I believe I can scale the instance type up or down as needed using the current generation of available machines, but haven't tried this yet.
Boots to 'root' by default.
How can I add Network Interface and private IP in CentOS?
I have already added the network interface and IPs from AWS panel, but what i should do in CentOS?
