1This includes both Standard and Premium storage accounts. If you require more than 200 storage accounts, make a request through Azure Support. The Azure Storage team will review your business case and may approve up to 250 storage accounts.
2Ingress refers to all data (requests) being sent to a storage account. Egress refers to all data (responses) being received from a storage account.
3Azure Storage replication options include:
- RA-GRS: Read-access geo-redundant storage. If RA-GRS is enabled, egress targets for the secondary location are identical to those for the primary location.
- GRS: Geo-redundant storage.
- ZRS: Zone-redundant storage. Available only for block blobs.
- LRS: Locally redundant storage.
