most of my bad experience with Azure is the control interface, which is worse than AWS/GCP in every way
random incomprehensible error messages, near constant UI timeouts and terrible UI performance and experience (artifact deployment has been "skipped"? why? no way to know), etc
the Windows VMs are also extremely slow compared to my employer's non-azure VM, with the Azure VMs having double the VCPUs, disk IOPS and RAM (despite having the same "stack" deployed on it)
