What is Azure storage made of, the underlying storage technology which supports the Azure storage we access in azure portal?
Is it object based storage or block storage (persistent/ephemeral) similar to categorization in Ceph?
If there is a mix of block and object based, which storage is used for each of exposed Azure storage service - block blob, append blob, page blob, storage tables, storage queues, Azure files
A few years ago, Azure Storage team made a presentation about internals of Azure Storage at 23rd ACM Symposium on Operating Systems Principles (SOSP).
