# Red Hat OpenShift Service on AWS endpoints and quotas
<a name="rosa"></a>

Red Hat OpenShift Service on AWS (ROSA) currently does not support programmatic access to service endpoints via the AWS CLI. The following are the AWS Regions and service quotas for this service. Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html).

## Service quotas
<a name="limits_rosa"></a>

ROSA uses service quotas for Amazon EC2, Amazon Virtual Private Cloud, Amazon Elastic Block Store, and Elastic Load Balancing. These quotas are listed in the corresponding namespace in the Service Quotas console. Although most default values are suitable for most workloads, you may need to request a quota increase for the following cases.
+ ROSA classic clusters require a minimum of 100 vCPUs for cluster creation, availability, and upgrades. The default value for Running On-Demand Standard (A, C, D, H, I, M, R, T, Z) Amazon EC2 instances is 5 vCPUs. If you do not increase this quota, cluster creation fails.
+ Some optional cluster configuration features, such as custom security groups, may require you to request a quota increase. For example, ROSA associates one security group with network interfaces in worker machine pools by default. Because the default quota for security groups per network interface is 5, if you want to add 5 custom security groups you must request a quota increase to bring the total number of security groups on worker network interfaces to 6.

To increase quotas, open the [Service Quotas console](https://console.aws.amazon.com/servicequotas/home/services/ec2/quotas/L-1216C47A) and request a quota increase. For more information, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*.

**Note**  
You can check your quotas using the AWS SDKs, but the SDK calculation doesn't include existing ROSA resources. The quota check in the SDK may pass, and ROSA cluster creation may fail. To fix this issue, open the [Service Quotas console](https://console.aws.amazon.com/servicequotas/home/services/ec2/quotas/L-1216C47A) and request a quota increase.


**ROSA-required quotas**  

| Name | Service code | Default | Minimum required | Adjustable | Description | 
| --- | --- | --- | --- | --- | --- | 
|  Running On-Demand Standard (A, C, D, H, I, M, R, T, Z) instances  | ec2 | 5 | 100 | [Yes](https://console.aws.amazon.com/servicequotas/home/services/ec2/quotas/L-1216C47A) |  Maximum number of vCPUs assigned to the Running On-Demand Standard (A, C, D, H, I, M, R, T, Z) instances. The default value of 5 vCPUs is not sufficient to create ROSA clusters. ROSA requires 100 vCPUs for cluster creation.  | 
|  Storage for General Purpose SSD (gp3) volumes, in TiB  | ebs | 50  | 300 | [Yes](https://console.aws.amazon.com/servicequotas/home/services/ebs/quotas/L-7A658B76) |  The maximum aggregated amount of storage, in TiB, that can be provisioned across General Purpose SSD (gp3) volumes in this Region.  | 
|  Storage for General Purpose SSD (gp2) volumes, in TiB  | ebs | 50  | 300 | [Yes](https://console.aws.amazon.com/servicequotas/home/services/ebs/quotas/L-D18FCD1D) |  The maximum aggregated amount of storage, in TiB, that can be provisioned across General Purpose SSD (gp2) volumes in this Region.  | 
|  Storage for Provisioned IOPS SSD (io1) volumes, in TiB  | ebs | 50 | 300 | [Yes](https://console.aws.amazon.com/servicequotas/home/services/ebs/quotas/L-FD252861) |  The maximum aggregated amount of storage, in TiB, that can be provisioned across Provisioned IOPS SSD (io1) volumes in this Region.  | 

**Note**  
The default values are the initial quotas set by AWS. These default values are separate from the actual applied quota values and maximum possible service quotas. For more information, see [Terminology in Service Quotas](https://docs.aws.amazon.com/servicequotas/latest/userguide/intro.html#intro_getting-started) in the *Service Quotas User Guide*.
