You are deeply embedded in the rest of the Azure ecosystem, and need eventing features to trigger Azure Functions. Or, if you need Extra Redundancy Tiering.
You don’t access your files all the time, but when you do, you need them accessed quickly (a.k.a. “hot”) and cheaply (free, in Wasabi’s case). Wasabi is akin to getting the good pricing of an Archive tier of storage but without the large fees (within minutes) and long waits (near-instant instead of hours or days) for data retrieval. It’s a “hot” archive.
