With Service Quotas, you can view and manage your quotas easily and at scale as your AWS workloads grow. Quotas, also referred to as limits, are the maximum number of resources that you can create in an AWS account. AWS implements quotas to provide highly available and reliable service to all customers, and protect you from unintentional spend. Each quota starts with an AWS default value. Based on your needs, you can request to increase quota values for your specific account.
