You answered the question but I was looking for more details. The term you called \
"ENI" is new to me, so what kind of device is it? It must be one of this: 1. Emulated \
Device (I suspect this is the one; because DPDK API works without any change) 2. \
Para-virtual Device 3. Directly Assigned Device
4. Fully customized Device (i.e shared memory with GrantTable mechanism)
	       or
5. A generic wrapper device (covering all of the above devices)

Thanks,
Rashmin

I have only experimented with C3.8xlarge instances with DPDK. You have to attach at \
least 2 ENIs to the instances since one of them would be taken over by DPDK. Based on \
the size, you would be able to attach 8, 16  or 32 ENIs to the instances (these will \
be visible as ethn devices of ifconfig)

Let me know if this helps (or I am not getting the question :) )

Hi Shawn,

Which network interface is visible to the VM? I mean which is the virtual ethernet \
port is used in Amazon-VM-DPDK app? And what all interfaces are offered based on the \
VM size and requirements?

Thanks,
Rashmin

Yes, you can.

> From my colleague, Saha, Avik, they are running  IntelDPDK 1.7 on c3.8xlarges.

Thanks.

Hi Patel,

The customer consider that deploy DPDK application in Amazon VMs is very flexible and \
very easy global site deployment:

such as: they only need to buy a 2 lcores VM if a site only need 200Mbps throughput;  \
buy one 4 lcores VM if the throughput is 400Mbps;

the can buy different Amazon site VMs in US, German... for lower access latency;

It really depends on the devices offered in the VM. If direct device assignment is \
not provided to a VM or if the node hypervisor doesn't have an optimized para-virtual \
interface to a VM, I don't see any benefit using DPDK in VMs.

A customer plan to buy some global Amazon VMs to run their DPDK 1.3(will upgrade to \
DPDK1.6 or 1.7) based VPN applications on global sites.

Thanks a lot;
