Hi, there are some people who would like to be able to launch instances into a specific subnet attached to their VPC in EC2. In looking at how to do this without going down the rathole of supporting everything related to VPC's, this is the plan I've come up with.
The assumption is that users will set up VPC's and subnets outside of DC. Once they have subnets, they will show up as realms with the EC2 driver. IOW, GET /realms will not only list availability zones like us-east-1a, but also subnets in those AZ's, i.e. realms that will be named something like us-east-1c:subnet-deadbeef; when launching an instance into such a realm, the create_instance call will pass the subnetID to AWS' RunInstances, rather than an AZ. any objections to this ?
