TL/DR OVH is the only European competitor of AWS, Google Cloud or Azure in terms of variety of services. And it's not exactly there either. If you only use EC2 and databases you can find some, not many, alternatives.
I wanted to move some of my operations to Europe because I was concerned by the data I stored in my US servers, being Amazon AWS and Digital Ocean my current providers. Sometimes the jurisdiction of your servers are as important as the price you pay for them.
I don't want to waste your time, here's what I gathered.
|ovh.com||AWS-like||France||It is trying to position itself as the European alternative to Amazon AWS on top of OpenStack. It does provide many services in addition to the classic VPS. It also shares something I dislike about AWS, a confusing management panel. OVH is well known all over the world, and the prices are good (Bandwitdh VS AWS is basically free). Support is terrible though.|
|Scaleway.com||DO-Like||France||Another cheap French supplier. It tries to compete with DO, although the truth is the offer is somewhat more limited. The management panel is easy to understand, something you'll appreciate if you're one of those who, like me, hate to spend time learning stupid acronyms.|
|Exoscale.com||DO-Like||Switzerland||Offers services beyond VPS, but offer is also limited against DO. For example, it does not offer databases. If this anecdata is of any use to you, I've read that CERN has contracted its services, but it could be for anything non-critical.|
|Hetzner.com/cloud||Do-Like||Germany||Something similar to the previous one. It has something interesting on a network level, but it really lacks databases and many other products. It's cheap, though. I didn't have good experience with them years ago, but everyone talks nice about their cloud service. A curious fact is that the game Krunker.io seems to be on top of Hetzner.|
|scalingo.com||Heroku-like||France||This one really looks nice. Everyone I've talked to about your service is happy. The offer is good. You have containers, databases and networking. Prices are okay.|
|clouding.io/en||VPS||Spain||The offer is very simple, only VPS, although the configuration is very flexible. They also offer Windows 2016 Datacenter for a small fee (+3€/month), which may be interesting for some uses. Personally I have used them for some side-projects, and it works fine.|
|upcloud.com||Do-Like||Finland||A very similar service to Exoscale. It tries to compete with Digital Ocean, but the services offered do not include databases, although they do have block storage.|
|fortrabbit.com||Heroku-Like||Germany||Similar to Heroky and Scalingo, but for PHP. Sadly, it only offers MySQL and it's really running on top of AWS|
Other interesting services:
|cloud.yandex.com||Google-Like||Russia||Well, if you wanted to move your data out of the U.S. maybe you are not confortable putting it in the hands of a Russian company, but the truth is that Yandex is interesting, because it has from a cloud service to its own browser, through an analytics service (which I do use, and which I like quite a lot), and of course a search engine. I haven't found a way to put the prices in Euros.
Russia is a big and, let's say, motivated country, but it's striking that in Western Europe we haven't been able to develop a service that can even compete with Yandex.
You may also find it interesting to read a little about Ilya Segalovich, one of its co-founders.
|alibabacloud.com||AWS-Like||China||Obviously in China they were not going to stay out of this market. Alibaba's offer is obviously not appealing to those who are concerned about what is done with their data, but the truth is that it is very complete, and I would say that, at least on paper, it can compete with AWS. Personally I haven't tried it, and I don't think I will. If one day I have a website aimed at the Chinese market I probably host it in Singapore or something like that, despite 'Strikingly'.|
There are many more companies out there, but the truth is that the offers didn't seem too appealing to me, if only they were limited to selling old-fashioned VPS blocks.
In any case, the reality is that no one in Europe competes with AWS, Google Cloud or Azure with the same range of services and integration (Well, maybe Yandex if we consider Russia). OVH is approaching, and really if you wanted to set up your own Kafka-type service you could, but really the appeal of these providers is to save you that work.
Surely governments and big companies have access to services that the rest of us mortals don't have (for example, through companies like Atos, Indra, DT, etc), but I have no way to evaluate them, and I couldn't hire them anyway.
