Service Limitations | AWS
AWS has service limits to protect you from unexpected excessive provisioning, as well as protection from malicious actions intended to increase your bill, as well as to protect the service endpoints. The service limit is the quota or allowance set on a resource. For example, a tenancy is allotted a maximum number of compute instances per availability domain.
