Azure is paying the penalty for being late to the game. They are making the exact same mistakes AWS made with the whole service fragmentation with the introduction of VPCs, except with azure its fragmentation of ARM vs Classic. fragmented UIs, fragmented documentation, fragmented CLIs (literally, the powershell and the xplatform cli have totally different sets of commands). They are slowly making progress. Disk IO isn't horrible, you just have to over-provision premium storage when it really matters (just like you do in AWS with GP2 volumes). That said, their concept of storage accounts for housing volumes/disks is absolutely horrible. Luckily I hear mumblings of change there.
