The actual migration, a day or less. Now there was a 2-week sprint for testing and validating backup and restore before doing the actual migration. At the non-engineering level (management and such) of course there was a review and consideration time as well.

Good question.

I'd also like to hear more detail (budget, time, people and skills) on real cases.

When I had research students I set a few of them doing studies on migration, degoogling, data "repatriation" (ick!) and all the things I think we now call "sovereignty". But there was lots of theory and precious few solid, documented studies. There were also hundreds of propaganda pieces and Google/Microsoft/Amazon shill pieces sowing disinfo.

Surely that's changed now and the economic realities are clearer?

That's already answered in OP's article.

S3:

> AWS S3 is the premier cloud-based object storage service. It may have higher availability, but it’s three times more expensive than OVH’s S3 storage.

The reliability of OVH has so far not been a problem. Performance is mostly a factor of the VM instances that you use, AWS has much more instances to choose from, but obviously at a much higher cost, so performance per dollar is obviously better with OVH.

We are already available in Europe; it is just our infrastructure that is currently more us-centric in that sense.

Eventually as the demand grows we will of course deploy in EU region to improve the availability.

If it is more of a sovereign aspect; we are deployable on kubernetes;one can already use our installer on OVHCloud and deploy on a European region.

One obvious benefit of OVH compared to Hetzner is the S3 storage, the Kubernetes framework and a number of other services provided by OVH, don't think Hetzner would provide those services.

Long time Hetzner user, but I would not trust new system (S3 storage) in this case for things beyond playground and tests until it has at least couple of years in production - Hetzner just made it public in ~ Nov 2024.

You'd be surprised :) We had to migrate a few thousand projects and their feature data and users' custom images. It was substantial. (eng@Hopsworks)
