I have a working Elastic Cloud deployment (as an ISV) on my Azure subscription. I am using the platforms' Azure blob connector to sync documents from a Blob container to Elasticsearch.
Since the ES deployment is not on my Azure subscription- I want to secure and restrict access to my Blob storage.
On the face of things I have two options: either use a PrivateLink or specify IP filtering on my blob storage based on the Elastic Cloud static IP list provided here.
When I configured the static IPs in the Blob storage networking pane and tried running the Blob storage sync, I got an AuthorizationFailure; Unfortunately without specific details.
Is what I am trying to do even possible or is PrivateLink my only option? Perhaps there is some other IP range I am missing.
