Auzre Storage

Generate SAS Tokens in ARM Templates Without much fanfare, MS recently updated the ARM template spec to allow the creation of SAS tokens inside a template. This is excellent news for anyone who is deploying resources with ARM templates that rely on storage accounts and need a SAS token to access them. For those not familiar with SAS tokens, you can read more on them here but essentially Shared Access Signatures (SAS) provide a way to generate a key to undertake operations on a storage account, without needing the actual storage account key.

Azure Premium storage is a relatively new Azure feature that lets you replace your standard storage account with high performance, lower latency storage at an additional cost. Throughput of up to 200MB/s can be achieved with a single disk, and even more if multiple disks are combined on a single server. This all sounds great, but users of Premium Storage may find themselves disappointing when first testing this hardware, and receive less than advertised performance.
