ROSA service quotas
Red Hat OpenShift Service on AWS (ROSA) uses service quotas for Amazon EC2, Amazon Virtual Private Cloud (Amazon VPC), Amazon Elastic Block Store (Amazon EBS), and Elastic Load Balancing (ELB) to provision clusters.
Required minimum quotas for ROSA
For the following Amazon EC2 and Amazon EBS quotas, ROSA requires a higher quota than the default service provides. To use ROSA, you may need to request an increase for these quotas. For more information, see Requesting a quota increase in the Service Quotas User Guide.
Important
For On-Demand Standard (A, C, D, H, I, M, R, T, Z) Amazon EC2 instances, the default value of 5 vCPUs is not sufficient to create ROSA clusters. ROSA requires 100 vCPUs or greater for cluster creation. To increase this quota, open the Service Quotas console
Note
You can check your quotas using the AWS SDKs, but the SDK calculation does not 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

The default values are the initial quotas set by AWS, which are separate from the actual applied quota value and maximum possible service quota. For more information, see Terminology in Service Quotas in the Service Quotas User Guide.
