I feel like hardly anyone in Germany knows how to pronounce Azure (myself included for the longest time). There are no other common words like it, and what feels like the most obvious pronunciation is far from the correct one.
There are many differences in pronunciation between English from various countries. E.g. in Australia we say Mo-bile were "bile" rhymes with "vile" whereas Americans typically pronounce it as Mo-bol.
There are lots of others.
There are dozens of dialects/pronunciation styles in the US. What you may have heard from some US folks isn't what you'll hear from others.
As an American who lives in the US, I have never heard anyone say 'Ay-zure', WRT to either the color or the "someone else's server' offering from Microsoft.
As for Mobile, there are multiple pronunciations in various places around the US. Anything from 'mo-b-aye-l' (as you Aussies say) to 'mob-ill' (as in mafia) to 'Moe-bill' (as in one of the Three Stooges) to 'Mo-beel'.
Then again, I live on the east coast and those west coast weirdos sure do talk funny.
Edit: Clarified "pronunciation" of Mobile (with long 'o' and 'i' and silent 'e').
You can mispronounce all sorts of things in the US and no one will blink an eye, but you mispronounce a town name, prepare to be dogpiled. Especially if you're in Palestine, Texas (Pal-es-teen NOT Pal-es-tine).
The way I learned it (US), "mo-bile" is the adjective for something that can move, "mo-beel" is a noun for the thing that you hang over a baby's cradle.
That's also mo-bile in my experience, unless you've been hanging snowmobiles...
