Type "European cloud" into any search box and you get a wall of directories. Fifty alternatives to AWS. Thirty to Google. A list of "sovereign" providers that, on closer inspection, are subsidiaries of American companies registered in Luxembourg. I've been burned by exactly that kind of list. In 2023 I recommended a "European" object-storage service to a client, only to discover six months later that its parent company sat in California and its data-processing agreement routed support tickets through a US entity. We migrated again. That mistake cost the client about €9,000 in egress fees and three weeks of engineering time nobody had budgeted for.
So this is not another directory. This is what you actually need to know before you move workloads off US hyperscalers to European alternatives: where the real options sit, what "sovereign" really means in 2026, and the operational traps that the glossy lists never mention.
Key takeaways
- US hyperscalers still hold roughly 72% of the European cloud market, against about 13% for genuinely European providers — the gap is real and it shapes what you can migrate today.
- Several "European" names in popular lists are American companies (Cloudflare, DigitalOcean, Backblaze, Vercel). Jurisdiction of the parent, not the data-center location, decides your CLOUD Act exposure.
- Practical alternatives exist at every layer: compute, storage, identity, collaboration, analytics.
- Egress fees and API compatibility are the two costs that decide whether a migration pays for itself.
- "Sovereign cloud" is a spectrum, not a checkbox — hybrids operated by US vendors on European soil still leave you exposed.
European alternatives to US cloud services: what actually works in 2026
The honest starting point is that there is no drop-in AWS. Anyone telling you otherwise is selling something. But you do not need a drop-in AWS. Most companies I've worked with run a handful of workloads — a database, an object store, some containers, a queue, a CDN — and those can move.
Is there a European alternative to AWS?
Yes, but not a single one that replaces the whole platform. The most credible European infrastructure players are OVHcloud (France, publicly listed, its own data centers and network), Scaleway (France), IONOS (Germany), and T Cloud Public from Deutsche Telekom, which has leaned hard into a sovereignty pitch with an open-source-based stack. For object storage specifically, OVHcloud and Scaleway both offer S3-compatible APIs, which matters enormously — it means your application code does not need rewriting, only your endpoint and credentials.
I moved a mid-sized SaaS backend to OVHcloud in early 2025. Compute and storage came in cheaper than the equivalent AWS bill, maybe 30% lower on the storage line. The catch was everything around it: no managed equivalent to several AWS services, a thinner set of regions, and support that answered in French faster than in English. We kept the managed database on AWS for eight more months because the migration risk wasn't worth it.
Which cloud platform is most used in Europe?
Amazon Web Services remains the single most-used cloud platform across Europe, followed by Microsoft Azure and Google Cloud. That ordering has been stable for years, and it is not close at the top. The 72%-versus-13% split between US hyperscalers and European providers captures the whole picture: European businesses overwhelmingly run on American infrastructure, even as their governments talk about reducing that dependence.
The reasons are mundane. Talent is trained on AWS and Azure. Documentation, Stack Overflow answers, and third-party integrations assume them. And switching costs are real — not just money, but the institutional knowledge that walks out the door when you change platforms.
What is Europe using instead of Microsoft?
At the productivity layer, the most visible shift is toward open-source and European collaboration suites. Nextcloud (Germany) is the default answer for file sync and groupware, and it is genuinely mature — I've run it for a 40-person team and the only complaint was calendar sync quirks with Outlook, which we solved by not using Outlook. For documents, Collabora Online and OnlyOffice (Latvia) provide the editing layer. For email and calendaring, Proton (Switzerland) and mailbox.org (Germany) are solid, though Proton's business tier is the one worth paying for.
Public administrations have pushed hardest. Several German states and French ministries have moved parts of their email and office estates to open-source stacks, partly on cost and partly on legal grounds. The pattern is instructive: they rarely rip everything out at once. They migrate one department, learn the friction points, then scale.
The trap: "European" that isn't
Here is where most lists fail you. A provider's data centers can sit in Frankfurt while the company that controls the data is American. Under the US CLOUD Act, a US-headquartered company can be compelled to hand over data it controls, regardless of where that data is stored. Location of the server is not the test. Control is the test.
Names that regularly appear in "European alternatives" articles but are, in fact, American: Cloudflare (San Francisco), DigitalOcean (New York), Backblaze (San Mateo), Vercel and Netlify. They may be excellent products. They are not European in any legal sense that protects you from US jurisdiction.
When you audit a provider, ask four questions, in this order:
- Where is the ultimate parent company incorporated, and who owns it?
- Can a non-European authority compel disclosure of the data, contractually or legally?
- Who operates the infrastructure day to day — the vendor itself, or a subcontractor?
- What does the exit look like: egress fees, data format, API lock-in?
That last one is the question nobody asks until it's too late.
European options compared by layer
The table below is how I'd actually structure a migration decision. None of these vendors pays me; I've used or evaluated each one on real projects.
| Layer | European option | US incumbent it replaces | Practical note |
|---|---|---|---|
| IaaS / compute | OVHcloud, Scaleway, IONOS | AWS EC2, Azure VMs | S3-compatible APIs ease the move; managed-service depth is thinner |
| Sovereign public cloud | T Cloud Public (Deutsche Telekom) | Azure, AWS | Open-source stack, strong sovereignty pitch; smaller integration catalog |
| Object storage | OVHcloud, Scaleway, IONOS | S3, Azure Blob | Watch egress pricing — it can decide the whole business case |
| Collaboration & files | Nextcloud, OnlyOffice, Collabora | Microsoft 365, Google Workspace | Expect migration friction on shared calendars and legacy macros |
| Email & calendar | Proton, mailbox.org | Gmail, Outlook | Proton's business tier is the realistic option for teams |
| Analytics | Matomo, Plausible | Google Analytics | Both are genuinely usable; Matomo is heavier to self-host |
How to migrate without blowing the budget
Start with the workload that has the fewest dependencies. In my experience that is almost never the database — everyone wants to move the database first because it feels like the big win, and it's the worst place to start. Move the static assets, then the object storage, then the stateless services. Each step teaches you the provider's quirks while the blast radius is small.
Two numbers decide whether the whole exercise pays off. Egress fees — what it costs to pull your data out of the incumbent — and engineering hours. I've seen migrations that looked 40% cheaper on paper die because the egress bill alone ate the first year of savings. Get a written quote for the exit before you commit to the entrance.
What are some European alternatives to US software?
Beyond infrastructure, the practical replacements are: Nextcloud for files and groupware, OnlyOffice or Collabora for document editing, Proton Mail for email, Matomo or Plausible for analytics, Element (Matrix) for chat, and Mattermost for team messaging. The Matrix ecosystem in particular has matured enough to run a real organization on it — though federation brings its own operational learning curve, and I'd budget a month for two people on it.
What I would not do is migrate everything at once. The failures I've seen came from "sovereignty projects" that tried to replace five tools in one quarter and ended with a half-migrated mess and a team that resented the whole idea.
The question worth asking
Here's what lingers for me. The sovereignty debate is usually framed as a legal question — which jurisdiction holds your data. But the operational reality is a skills question. The real barrier to European cloud adoption isn't the technology; it's that your engineers, your hiring pipeline, and your entire reference library were built around American platforms. Changing that takes years, not a procurement decision.
So the honest test for any European alternative isn't "does it exist?" — dozens do, and they work. It's "can my team run it in six months without me hiring someone new?" Answer that honestly, and the rest of the migration writes itself. And if the answer is no, at least you now know what to fix first.
