SigParser

If you don't want to use the local storage on your server where the On Premise engine is deployed you can instead use Azure Storage. Be careful the storage account is not public. 

The Azure Storage option has pros and cons. The pro is the storage can grow forever but you are unlikely to need that much storage because the storage is only used when the SigParser API is unreachable which isn't often. The con is that it is harder to setup and managing connection strings becomes an additional burden.

Create an Azure Storage Account (optional)

In Azure Portal, search for Storage accounts

1. Choose the appropriate subscription &amp; resource group
2. Specify the storage account name, something like sigparserstorage
3. Choose Standardperformance
4. Choose StorageV2 (general purpose v2)
5. Choose Locally-redundant storage (LRS)
6. Choose Next to proceed to Networking
7. Choose Public endpoint(all network) 
 1. The storage account's contents should not be made public. This settings just controls the endpoint for this storage account. 
 2. You can make a private endpoint but it requires a private DNS and a network interface (NIC).
