  1. Amazon EC2 preserved instances pricing scheme
  2. Amazon EC2 Rails roundup: 2 small instances vs 1 high CPU medium instance
]]> I recently switched an Amazon instance to the new Amazon reserved instances price scheme. At first I was confused how to do that. Amazon doesn’t provide an interface for buying a preserved. In fact you have to use the EC2 tools and command line to do. I am comfortable to use the command line, however, I never used the command line to buy something.

First, you need to install the EC2 tools. You can find a guide here. After installing the EC2 tools, the following command lists all reserved instances:

ec2-describe-reserved-instances-offerings

This results in the following output:

So, to reserve one small instance in the us-east-1a region, just type

ec2-purchase-reserved-instances-offering -c 1 -o 248e7b75-0799-4a55-a0cb-f8d28eb11921

then press enter and you are credited 500 USD plus 100 USD taxes. However, in 300 days the command pays for itself.
