How does ansible make it straighftorward? As far as I know, it neither helps with networking failover, load balancing, data consistency, or other aspects of distributed systems, and running one application across clouds is certainly a distributed systems problem, not a deployment problem.

Ansible helps deploy software, but deploying software is the smallest problem of going multi-cloud.

I know what ansible is and can do. Your other comment is about how it can provision and deploy things. While true, it's unrelated to my point that that's the least of your problems in a multi-cloud world.

A lot of that depends on scale too. I was mostly talking about the ability to standardize configuration so that you could replicate your infrastructure on multiple providers. Essentially just making sure that you have a backup plan/redundancy in case something happens and you find yourself needing to spin things up elsewhere on short notice.

You're absolutely right that running them at the same time, data syncing, traffic flow, etc is much more complicated.
