Richie Rump has some nice pointers about developing for Azure or AWS:
Since we’re a bunch of data freaks, we wanted to make sure that our data and files are properly backed up. I set out to create a script that will backup DynamoDB to a file and copy the data in S3 to Azure. The reasoning for saving our backups into a different cloud provider is pretty straightforward. First, we wanted to keep the data in a separate cloud account from the application. We didn’t make the same mistakes that Code Spaces did. Secondly, I wanted to kick the tires of Azure a bit. Heck, why not?
I figure this script would take me a day to write and a morning to deploy. In the end it took four days to write and deploy. So here are some lessons that I learned the hard way from trying to bang out this backup code.
This is a must-read if you’re starting to look at using cloud providers for services.
