Amazon EC2 Service Quotas - Amazon Elastic Compute Cloud

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 AWS account, we set default quotas (also referred to as limits) on these resources on a per-Region basis. For example, there is a limit on the number of instances that you can launch in a Region. Therefore, when you launch an instance in the US West (Oregon) Region, the request must not cause your usage to exceed your current instance limit 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 AWS infrastructure. Plan to request any limit increases in advance of the time that you'll need them.

For more information, see Amazon EC2 endpoints and quotas in the Amazon Web Services General Reference.

Limits on email sent using port 25

Amazon EC2 restricts traffic on port 25 of all instances 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 EC2 instance? in the AWS Knowledge Center.
