So this is for IO- and CPU-bound users who for some reason are also EC2-bound.

Can anyone give me the advantages of choosing an EC2 dedicated host over going with a true dedicated server?

All the advantages of a dedicated server without the hassle of saving tons of money.

Well, dedicated hardware for EC2 makes sense for certain workloads (eg when you need more predictable performance), considering that you can use them alongside other AWS services (EBS, RDS, Route 53, S3, etc). Plus allocating 'bare metal' VMs on demand via script/API is a big plus.

It would be interesting to see how much you can squeeze the dedicated hardware with the largest EC2 types though.

According to their docs/examples, this is mostly for legal reasons. i.e. some software can be licensed to multiple VMs if they are all running on the same host.

All the rest of your infrastructure is in AWS and you want the high interconnect speeds.

Many of our customers have asked for this feature so that they can run software that is licensed for a particular piece of actual hardware.

This is very far from 'bare metal'.

To save a trip to the calculator: $2.341 (m3 host / hour) * 24 hours * 30 days = $1685.52 before the "up to 70%" reservation discount.

Bare in mind that can run up to 32 m3 instances

What's the networking model? Will two instances on the same host talk over the datacenter network, or will the traffic stay local to the machine?

Are the hardware specs available somewhere? Is it possible I'm confusing this with an interface for launching EC2 instances at a premium disguised as being actual dedicated hardware?
