I'd really like to see a more a-la-carte option. For example: I have an app that might in the future require a lot of network, a decent but not terribly huge amount of CPU, but very little memory or storage. I'd like to be able to provision an instance with, say, 512MB RAM, 2GB disk, 10 gigabit Ethernet, and CPU optimized for single-threaded performance with only 2-4 cores. Amazon and most other large cloud providers seem to assume that demand for everything increases together, which doesn't apply to every work load.
That's where I think containers come in handy. Assuming you have other services you are managing you can pack them into instances running your main workload. https://aws.amazon.com/blogs/aws/cloud-container-management/ will likely make that very easy to manage, assuming you are willing to go all in with Amazon.
I wonder what volumes Amazon buys in order to get Intel to make a custom part number for them. Do they design their own servers?
