We're fast approaching the big freeze, so I wanted to start to summarise up the status of the EC2 AMIs.
Thanks to Eric Evans, Python-Boto 2.33 hit testing in the last few days. This represents a huge step forward from Wheezy's current 2.3.0, bringing not only many more services, but one of my favourites, support for IAM Roles for EC2 instances. There is only one newer upstream release of boto (2.34), which unfortunately contains support for the latest AWS Region in Frankfurt , but with a freeze due now its not going to make it.
The Jessie images I have been creating  have worked well for me. Improvements over Wheezy includes:
- - correct usage of grub (Jessie's grub is not as broken as the 1.99 we have in Wheezy).
- - SR-IOV (Enhanced Networking, low jitter), through the Jessie kernel 3.16-3 includes sr-iov 2.12.1 (run "modinfo ixgbevf" and look for Version), which works but is below the recommended 2.14.2 
- - support for multiple ENIs via DHCP
- - support for sub-interfaces via a DHCP script (and metdata server info)
- - AWS CLI (package awscli) version 1.4.2 (upstream is 1.5.4; differences are here ) is installed
With the rise of HVM replacing PVM in the AWS environment, and every new instance providing more and more memory, I'm going to suggest a few things.
First, many providers are now signalling the end of i386 images, and I am going to propose that we do similar for Jessie. Wheezy has supported multiarch, so i386 binaries can run on an amd64 image.
Second, with all current-generation instance types being HVM capable, I am going to suggest we no longer generate Paravirtualisation images. The current-generation instance types are generally cheaper and/or more resource (memory, CPU) than the previous-generation PVM-only instances, so users pretty quickly want only HVM amd64 across their entire set of instances.
This will reduce the number of images we're creating: HVM EBS backed, and HVM S3 backed. I suspect that simplifying this choice makes life easier for our users. At this stage, we haven't generated any HVM S3 backed Jessie images, mainly because euca2ools has a few bugs , and ec2-api-tools' ec2-bundle-image doesn't work on Jessie (as it requires a binary called 'grub', and that doesnt exist in Jessie as its all grub-* in Grub 2.xx on Jessie).
Jessie (HVM, amd64, EBS) test images have been put into all AWS Regions (North Virginia, Northern California, Oregon, Ireland, Frankfurt, Singapore, Tokyo, Sydney, Singapore, and the isolated/separated Regions of Beijing and US Gov Cloud).
So what's missing?
* cfn-init, cfn-signal, cfn-hub tools for CloudFormation  would be one on my wish list.
* Base image with the non-free nvidia drivers pre-installed for the g2 (GPU) instance type - I have tested this by manually installing the drivers using nvidia-kernel-dkms but not scripted it or produced Debian blessed images already containing this.
* Having a working bundle-image for S3 images for Jessie.
Does anyone here have any other requests?
Now some numbers for you. Debian's AMIs are shared to users/customers in the EC2 environment in two ways:
1) From the Debian AMI Account(s) directly, what AWS's called "Community shared", and are the AMI IDs that I publish here. There are three accounts: Beijing, GovCloud, and "Standard" rest-of-world. Any DD or DM that wants access into the account to have a poke around is welcome to - just ask me off list.
2) The AMIs generated in US-East-1 are duplicated into the AWS Marketplace by the Amazon Marketplace team, and in parallel gets distributed (with separate AMI IDs).
I don't have numbers on usage from 1), but from 2) I can tell you there are over 11,000 subscribers (customers, not instances). Furthermore, as some on this list have indicated, others in the EC2 environment generate their Community-Shared AMIs from these base Debian images, so the end number of instances is probably significant.
On a personal note, I no longer work for AWS, and as always, patches and assistance is welcomed.
