Amazon ECS service quotas
When you create your Amazon Web Services account, we set default quotas (also referred to as limits) on your Amazon resources on a per-Region basis. If you attempt to exceed the quota for a resource, the request fails.
The Service Quotas console is a central location where you can view and manage your quotas for Amazon services, and request a quota increase for many of the resources that you use. Use the quota information that we provide to manage your resources. Plan to request any quota increases in advance of the time that you'll need them.
Managing your Amazon ECS and Amazon Fargate service quotas
You can request an increase for Fargate quotas for your Amazon account. To
request a quota adjustment, contact the Amazon Web Services Support Center
