It can make a lot of sense. Store data at the provider that can do it best, analyze your data at another provider with a superior product. You'll find data centers of all major providers within a few miles of each other in at least 10 locations around the world. Latencies are <5ms and the links between those data centers are cheap and can provide huge bandwidths (even though they don't want you to know this and still charge huge prices). So from both a technical and an economical perspective there should be no reason why you can't shift terrabytes of data daily between GCS, AWS, Azure, Hetzner, OVH, Cloudflare etc. Only artificially high egress pricing set by the three biggest providers keeps people from doing that. In Europe with OVH and Hetzner that's exactly what a lot of people already do (from my experience), also nicely visualized in their Weathermap (look at Frankfurt) [1]. These two providers are tiny compared to AWS and yet the 400gbit/s links between them are utilized ~50% pretty much 24/7. And from my experience I can say that there are quite a few use cases where mixing these providers is cheap and easy. [1] http://weathermap.ovh.net/#europe http://weathermap.ovh.net/#europe
