Preview: New Basic SKU functionality for Azure confidential ledger

Azure confidential ledger is launching a Basic SKU to serve customers of other Azure products needing higher integrity protection. The Basic SKU will have limited transactions per second compared to the Standard SKU. It is ideal for cases where periodic hash digests are sent to the Azure confidential ledger for advanced integrity protection of your main data source. The Basic SKU will be free of charge for the duration of the gated preview.
