We have an internal system called Cosmos[0] that does a great job of processing huge quantities of data very fast. And we sat on it for years while the rest of the industry moved to Spark and its derivatives. We finally released it as Azure Data Lake Analytics (ADLA) but did a shit job of supporting/promoting it.

We built Synapse, and it's garbage. We've now got Fabric which I guess is the new Synapse. I wouldn't really know because I probably have five different systems that I use that basically do large-scale data processing, and yet Fabric isn't one of them; who knows, maybe it will become the sixth?

We've had numerous internal systems for orchestrating jobs, and it wasn't until Azure Data Factory that we finally released something externally that we sort-of-kind-of-but-not-really use internally. (To be fair, some teams do use it internally, but we're not all rowing in the same direction.)

I regularly deal with multiple environments with different levels of isolation for security. I don't even know how it's all supposed to work -- I have my regular laptop and a secure workstation and three accounts that work on the two. Yet I have to do some privileged account escalation to activate these roles; when I'm done, there's no apparent way to end the activation early, so I just let it time out.

These things are but a fraction of the Azure offerings, but literally everything I have used in Azure makes me absolutely HATE working in the cloud. There's not a single bright side to it AFAICT. As best as I can tell, the only reason why Azure makes so much damn money is because Microsoft is huge and can leverage its size into growth. We're very much failing up here.
