See azure doc[1], the naming rules on storage account name, it must be between 3 and 24 characters in length and may contain numbers and lowercase letters only.

The prefix of storage account created by installer seems changed to use infraID with CAPI-based installation, it's "cluster" when installing with terraform.

Is it possible to change back to use "cluster" as sa prefix to keep consistent with terraform? because there are several storage accounts being created once cluster installation is completed. One is created by installer starting with "cluster", others are created by image-registry starting with "imageregistry". And QE has some CI profiles[2] and automated test cases relying on installer sa, need to search prefix with "cluster", and not sure if customer also has similar scenarios.
