This is certainly... an opinion.
AWS's us-east-1 famously takes down either a bunch of companies with it, or causes global outages on the regular.
AWS has a terrible, terrible user interface partly because it is partitioned by service and region on purpose to decrease the "blast radius" of a failure, which is a design decision made totally pointless by having a bunch of their most critical services in one region, which also happens to be their most flaky.
I don’t see how you could care (a lot) about both the UI and reliability.
Nobody is winning any UX prize there. Azure, AWS, GCP... they are all terrible. Back then GCP for instance used to only work reliably on chromo-based browsers. Azure has that horrible overlay UI that abuses extended real estate that just doesn't work.
But azure wins most prizes for being terrible becuase, among other things, https://isolveproblems.substack.com/p/how-microsoft-vaporize.... It's not the worst provider maybe because oracle is somehow still kicking around.
Its just a bad product. Just like windows, OneDrive, teams and basically everything Microsoft has pumped out in the past decade.
Microsoft is in the top 5 most valuable companies in the world. It's got azure that is a huge cloud provider. And yet it was utterly unable to present its answer in the AI race. Not even a bad model with a half baked harness. Nothing. And meanwhile they are trying to port NTFS to low powered FPGAs because insanity. Just let that sink in.
