I generally worry about outsourcing a critical part of a business to one vendor without a plan for what happens if they go down. I'd ask the same question if people said they used AWS.

I agree to the general concept. I'm just curious about how you would handle it. Would you use AWS as backup to Azure and switch DNS when this happens?

Anyone else is welcome to pitch in here, I'm new to native cloud applications and find myself just waiting in this case.
