Amazon EC2 service quotas
Amazon EC2 provides different resources that you can use. These resources include images, instances, volumes, and snapshots. When you create your Amazon account, we set default quotas (also referred to as limits) on these resources on a per-Region basis. For example, there is a maximum number of instances that you can launch in a Region. So if you were to launch an instance in the US West (Oregon) Region, for example, the request must not cause your usage to exceed your maximum number of instances in that Region.
The Amazon EC2 console provides limit information for the resources managed by the Amazon EC2 and Amazon VPC consoles. You can request an increase for many of these limits. Use the limit information that we provide to manage your Amazon infrastructure. Plan to request any limit increases in advance of the time that you'll need them.

Restriction on email sent using port 25
On all instances, Amazon EC2 restricts outbound traffic to public IP addresses over port 25 by
default. You can request that this restriction be removed. For more information, see How do I remove the restriction on
port 25 from my Amazon EC2 instance or Amazon Lambda function?
