How to waste less money with AWS
First of all, you need to carefully select the region where you are going to stablish your servers.

How to survive with AWS EC2 T1.Micro instance
With my t1.micro, i can host my personal redmine, git and blog. But i couldn’t do that with default settings.
I have used swap on file to it and here is how you can do it:
Copy & paste the code below:
sudo su -c '
dd if=/dev/zero of=/var/swapfile bs=4096 count=524288
chown root:root /var/swapfile
chmod 0600 /var/swapfile
mkswap /var/swapfile
swapon /var/swapfile
echo "/var/swapfile none swap sw 0 0" >> /etc/fstab
'
To disable you can use:
sudo swapoff -v /var/swapfile
sudo rm /var/swapfile
sudo sed -i '/swapfile/d' /etc/fstab
