This is documentation for AWS M3 instances. This new generation of EC2 instances provides high frequency processors and offer SSD-based instance storage for fast instance store I/O performance.
The 64-bit instance types, available in all AWS regions, and optionally as dedicated instances, are:
* Extra large and double extra large instances are also available as EBS optimized instances.
This document describes how to use M3 instances with Engine Yard.
You can configure M3 instances when you add new instances to a new or existing environment.
Note: We recommend testing in a staging environment before applying changes in a production environment.
Ensure that you meet all the prerequisites above.
Add an instance in the usual way.
See the database docs for more information about adding a database instance to an environment.
Select the appropriate General Purpose M3 instance size in the list.
Click Add to Cluster (or Boot This Configuration, if you are re-booting an existing environment).
See the related documentation for more information on adding instances to your environment.
Note: If you are adding a M3 database instance, you also need to click Apply to update the database.yml file.
Note: When you are testing in staging, consider the differences between your test and production loads.
Ensure that instance provisioning worked and the instance is running.
In general, that is enough of an indication that the M3 instance is working fine.
You might have these questions about M3 instances.
You can leverage the SSDs as needed via custom Chef; be aware that there is no ability to create snapshots of SSDs.

How much does it cost? The pricing page doesn't say nothing about M3 instances, and with the C3 pricing your margin raised a lot for the same services
Here are our current prices for M3s. To anyone reading this in the future, please check out http://www.engineyard.com/pricing to be sure you're seeing the latest prices.
Also, our website pricing page is about to be fully updated with all the C3 and M3 pricing info.
FYI: It mentions "You can leverage the SSDs as needed via custom Chef" for both m3 and c3 instances. To save time for those looking how to do this, there is a little more to it... SSD support must be enabled by EY support as a feature flag for the environment/account, and can be requested via a support ticket.
Thanks for the note!
SSD support is not behind a feature flag, although it does require custom chef.
You may be recalling when M3/C3 instances were behind a feature flag and in early access? They have now been GA'd and are available directly from the drop down without enabling a flag.
