We have customers who require to have zone-redundancy for as much azure resources as possible, including Azure Compute Gallery. When creating an image version in a Azure Compute Gallery via NME the storage type/sku is always standard HDD LRS while some customers would like to choose another storage type/sku such as zone-redunant (or maybe also Premium SSD LRS)
Select storage type (sku) when creating image version in Azure Computer gallery via NME

Storage redundancy from LRS (99.999999999% availability) to ZRS (99.9999999999% availability) is only one extra "9" on the percentage. Nerdio can add mulitple replicas in the ACG and can also replicate the Images to another region for additional availability. As for the disk type of HDD-SDD in the ACG, there is not a need to pay higher disk cost with Premium SSD in ACG. The images are consuming only "Storage" resources and it would cost more money, for no value, than HDD images.
Hello Greg Roberson, thanks for the feedback.
- For you it might be "only" one extra "9" but if the customers wants to have that extra "9" (as the customer's SLA requests his) and customer wants to pay for it and the option is available in Azure Compute Gallery, I can understand that the customer wants to use it and wants to have it available from within NME.
- Replicas are meant for something else and can not be fully compared with redundancy supplied by ZRS
- Indeed SSD for ACG is least of customers concern in most cases, but I can image if you built-in the option to select "zone-redundancy" (ZRS) next to standard HDD LRS, it is also piece of case to add "premium SSD LRS" for those potential customers who want it
just my 2 cents...
Hi Greg Roberson
I am 100% with Joeri kumbruck.
As I understand it, I can have five copies in a region, which are then all in the same zone. Only when configuring zone redundancy is the image also available in the other zones.
So, if I create a host pool and distribute the resources to all zones, it may be that I can no longer deploy VMs in the event of a zone failure if this zone contains the images.
If a customer needs redundancy, they will also pay the extra costs.
I can configure my pool to use multiple zones to ensure availability in case of a single zone outage, but if my images are in the zone that's down, the pool won't be able to image new VMs in the other two zones, so I'll still have users down. I would agree that allowing the customer to select zone-redundant storage for the images is very important.
