Hi @Gregor Anton Grinč ,
When you create Cloud Shell using basic settings and select only a subscription, Cloud Shell creates three resources on your behalf in the supported region that's nearest to you:
- Resource group:
cloud-shell-storage-<region>
- Storage account:
cs<uniqueGuid>
- fileshare:
cs-<user>-<domain>-com-<uniqueGuid>
Using the advanced option, you can associate existing resources. When selecting a Cloud Shell region, you must select a backing storage account co-located in the same region. For example, if your assigned region is West US then you must associate a fileshare that resides within West US as well.
Please be aware about supported storage account region and security considerations.
