After using AWS for 3+ years and GCP for about 6 months, I can say Azure significantly lags behind them. Their service reliability is astonishingly poor. I think our most recent issue was 67 VM failures in a VMSS (of 55 nodes) backing AKS (Azure Kubernetes Service) in a single month. The health events said there were some kind of "remote storage errors" making the VMs unhealthy

That's a couple months after the Ubuntu/systemd incident (Azure's "blessed" Linux image is Ubuntu and it has unatttended-upgrades enabled including on managed infrastructure like AKS (where you can't turn it off without dirty hacks). A bad Ubuntu update caused hosts to lose their DNS from DHCP config rendering massive amounts of machines in partially broken states)
