Scaleway at least is genuinely not a bad alternative for this kind of thing already today - they do have plenty of managed services like serverless functions, object storage, queues, etc, in addition to the simple VMs and container hosting.
Scaleway (and I say this with very deep sadness) is pretty bad in terms of reliability right now, there are at least a couple big outages every year over the course of last few years that I've been using them.
Admittedly they have a new CTO who according to our support agent is very focused on improving that, so here's hoping, because otherwise their tech offering is very convenient.
