A HyperScale database can be created using the [Azure portal](https://portal.azure.com), [T-SQL](https://docs.microsoft.com/sql/t-sql/statements/create-database-transact-sql?view=azuresqldb-current), [Powershell](https://docs.microsoft.com/powershell/module/azurerm.sql/new-azurermsqldatabase) or [CLI](https://docs.microsoft.com/cli/azure/sql/db#az-sql-db-create). HyperScale databases are available only using the [vCore-based purchasing model](sql-database-service-tiers-vcore.md).

#### Notes on geo-restores of a Hyperscale database
145-
Because the source and target are in separate regions, the database cannot share snapshot storage with the source database as in non-geo restores, which complete extremely quickly. In the case of a geo-restore of a Hyperscale database, it will be a size-of-data operation, even if the target is in the paired region of the geo-replicated storage. That means that doing a geo-restore will take time proportional to the size of the database being restored. If the target is in the paired region, the copy will be within a datacenter, which will be significantly faster than a long distance copy over the internet, but it will still copy all of the bits.
