AWS - AMS on M3 Double Extra Large (m3.2xlarge)?

[SuhaGeisler]

Are there any plans on enabling AMS in AWS for instance type M3 Double Extra Large (m3.2xlarge)?

In general this instance type should be supported by AWS Marketplace...

We would like to use AMS on an instance with 8 vCPUs for less than the price of the already available, but old m2.2xlarge or m2.4xlarge.

I also don't understand why there is such a huge price-increase (just for the software-usage) on this two instance types compared to all other available instance types...
