Hi I have heard that the small EC2 instances are limited to around 35mbit/s. Does anyone have any figures for the different instance types and the size of their pipes?

We will be planning on using elastic load balancing but I'd really like to know what the limits of the external interfaces of the instances will be also.

I had running small instance as load balancer with traffic peaks to 80Mbit. So i guess there is no limit. Also thereis a thread, that states that it is 250Mbit bandwith for all.

Most instances have 1 Gbit shared with the other instances on that server, so your available bandwidth can vary quite a bit if the other tenants are busy beavers.

Cluster compute and GPU instances have 10 Gbit, again shared with any other instances on the host.

Upvoting because of the reference to the bandwidth being shared, however the link in the other answer states that each server only has a 0.25gb dedicated link do you have a source for this? Thanks! – scsmith Apr 14 '12 at 8:14
I'll see if I can dig up the source (it was a Twitter conversation involving an AWS evangelist). The 10 Gbit info can be found at – ceejayoz Apr 14 '12 at 13:45
