Wait, so we're talking about cloud services and messages, but no one's mentioned the cloud being made of cotton candy yet? I'm disappointed.

Hmm, I'm not sure about option B. Synchronous notifications? Sounds like the kind of thing that would make my computer crash. I'll go with A and D.

Event notifications crossing regions? That's pretty cool. I bet the data centers are really far apart. Like, on different continents or something.

I like how option C mentions the event notification message being retried based on the specified policy. That's a nice touch.
