If you use AWS for object storage: https://european-alternatives.eu/category/object-storage-pro...
If you use SES: https://european-alternatives.eu/category/transactional-emai... (but hosting your own is also a viable option)

There isn't any single provider that can match each and every AWS service. But for subsets of services there are options.
If there's a specific AWS service that you cannot get anywhere else but do absolutely need, that's vendor lock-in. Would it be fair to blame EU companies for your bad decisions?
Based on your comment you probably aren't gonna discuss in good faith but move the goalposts each time.
Whether you can switch from AWS to an EU alternative depends solely on how deep down the rabbit hole you are. If you're just looking for basics to host your stuff, you can. If you want to never have to touch Linux but to rely solely on proprietary abstractions on top of Linux, you can't.
What you've linked to is a broad scope site listing a multitude of EU based products and services, making it look like you cant even list ONE let alone a few .
Don't pull the 'moving the goalpost' nonsense, the original post you replied to made it very clear they were talking about an AWS comparison, and a cursory glance at the 'cloud providers' section of that site shows a bunch of EU hosting providers offering general VPS hosting, which isn't remotely close to being the same kind of thing.
I can see it coming already, no point in extending this thread
They may not have every single thing that AWS has but you can build solid infrastructure on top of those.
