So I'm guessing this will work mainly for customers that are running actual compute or K8S already?
The real challenge of a Cloud exit is undoing the years of gradually getting vendor locked-in. Not only do you use the services it provides, the software you might have written also uses the SDK's, is tightly coupled etc. I'm not even taking IAM into account, which is vertically integrated everywhere, in the equation.
And this isn't only on a technical level but also organizational. So i'm out of the cloud, my staff still doesn't know anything about managing dedicated servers and other solutions. I'm now fully dependent on a firm which main focus is doing migrations? How would that work?
What kind of business is your target audience here?
