Choose Azure Storage Class SKU

[J4bbi]

Because we need a ReadWriteMany shared volume between the web and the worker pods we need to procure an Azure Files provision. We then need to choose from different products, known in Azure as SKUs (Stock Keeping Unit). Different SKUs offer different levels of availability and backup strategies.

• Standard_LRS: Standard locally redundant storage (LRS)
• Standard_GRS: Standard geo-redundant storage (GRS)
• Standard_ZRS: Standard zone redundant storage (ZRS)
• Standard_RAGRS: Standard read-access geo-redundant storage (RA-GRS)
• Premium_LRS: Premium locally redundant storage (LRS)
• Premium_ZRS: Premium zone redundant storage (ZRS)

See further information: Azure storage redundancy SKUs.

The current development deployment uses Standard_LRS.

A final decision on this is required before production goes live.

@tnewburyimperial would you be able to look at this one please and advise?

LRS is fine for Dev to get us off the ground.

I do need to have a look at what would be more suitable for our Live service and what our appetite for risk is.
