Last month we got 5K bill from Azure for my production workload, $1160 only for blob storage.
I have a single storage account for all my services (Function, WebJob etc.), Under storage account, I'm only using Blob and I didn't store any big file on that account.
I have many Functions and Webjobs processing data from Eventhub and storing checkpoint information into block blob. One of my function processing 15M request per-day and storing Checkpoint in the blob.
I re-visit Microsoft documentation but unable to break this cost with my containers/Areas. Basically, I want to understand Storage, Ingress, Egress and Read/Write wise cost so I can take appropriate action.
