I’ve seen multiple projects founder on the complexity of writing software for the cloud. Moving data from here to there ends up being way harder than anybody expected. Maybe teams with more experience build this into their planning, but from what I’ve seen, if you’re using the cloud, your solution ends up being 95% about getting data where it’s supposed to be and 5% application logic.

This sounds a people problem, not a technology problem.

I’ve never had an issue with moving data.
