Compare cloud providers against your workload and its risk requirements—not by the labels “European” or “hyperscaler.” A useful shortlist weighs jurisdiction and operational control alongside service fit, resilience, security, cost, migration effort and exit options. The European Commission’s Cloud Sovereignty Framework is one current way to organize that review: it groups 48 criteria into eight categories.
Start with the workload, not the provider label
Write down what the workload must do and what would make it unacceptable to run in a particular cloud. A customer-facing application, a regulated data platform and a development environment may have different requirements for service capabilities, recovery, data handling and control. Treat those requirements as evaluation criteria before comparing vendor names.

“EU cloud provider” is not, by itself, a standardized technical guarantee. For each offer, establish separately where the provider is based and controlled, which entity signs the contract, where its data centres and staff are located, how the service is operated, and which technologies and suppliers it depends on. European data-centre location alone does not answer all of those questions.
Use a common comparison framework
The Commission’s Cloud Sovereignty Framework groups its 48 criteria into eight categories. Use the categories as a checklist, then add workload-specific questions and record evidence from each provider’s current contract, service documentation and architecture materials.
#1 Best Overall
- Entry-level NAS Personal Storage：UGREEN NAS DH2300 is your first and best NAS made easy. It is designed for beginners who want a simple, private way to store videos, photos and personal files, which is intuitive for users moving from cloud storage or external drives and move away from scattered date across devices. This entry-level NAS 2-bay perfect for personal entertainment, photo storage, and easy data backup (doesn't support Docker or virtual machines).
- Set Your Devices Free, Expand Your Digital World: This unified storage hub supports massive capacity up to 64TB.*Storage drives not included. Stop Deleting, Start Storing. You can store 22 million 3MB images, or 2 million 30MB songs, or 43K 1.5GB movies or 67 million 1MB documents! UGREEN NAS is a better way to free up storage across all your devices such as phones, computers, tablets and also does automatic backups across devices regardless of the operating system—Window, iOS, Android or macOS.
- The Smarter Long-term Way to Store: Unlike cloud storage with recurring monthly fees, a UGREEN NAS enclosure requires only a one-time purchase for long-term use. For example, you only need to pay $459.98 for a NAS, while for cloud storage, you need to pay $719.88 per year, $2,159.64 for 3 years, $3,599.40 for 5 years. You will save $6,738.82 over 10 years with UGREEN NAS! *NAS cost based on DH2300 + 12TB HDD; cloud cost based on 12TB plan (e.g. $59.99/month).
- Blazing Speed, Minimal Power: Equipped with a high-performance processor, 1GbE port, and 4GB RAM on Board, this NAS handles multiple tasks with ease. File transfers reach up to 125MB/s—a 1GB file takes only 8 seconds. Don't let slow clouds hold you back; they often need over 100 seconds for the same task. The difference is clear.
- Let AI Better Organize Your Memories: UGREEN NAS uses AI to tag faces, locations, texts, and objects—so you can effortlessly find any photo by searching for who or what's in it in seconds. It also automatically finds and deletes similar or duplicate photo, backs up live photos and allows you to share them with your friends or family with just one tap. Everything stays effortlessly organized, powered by intelligent tagging and recognition.
| Comparison area | What to establish | Why it matters |
|---|---|---|
| Strategic | Whether the service and provider align with the organization’s procurement requirements, dependencies and long-term plans. | A technically suitable service may still conflict with strategic or procurement constraints. |
| Legal and jurisdictional | The contracting entity, governing law, ownership and control, applicable government-access processes, and documented provider commitments for handling requests. | Data location does not by itself determine which legal processes may apply. |
| Data and AI | Where customer content, metadata, backups, logs, support records, telemetry and AI inputs or outputs are stored or processed; whether location commitments are service-specific; and which settings the customer controls. | Different data types and services may have different handling rules. |
| Operational | Who can administer the environment, from where and with what controls; how support and incident response work; and whether identity, DNS, key management and control-plane dependencies remain available during disruption. | Operational control and continuity involve more than the location of stored data. |
| Supply chain | Critical hardware, software, network, support and identity dependencies, including the effect of a third party becoming unavailable. | A service may depend on suppliers or components outside the customer’s direct control. |
| Technological | Required compute, accelerators, storage, databases, containers, analytics, AI, networking, identity and observability services, plus their availability in the target region. | A provider’s overall catalogue does not establish that a particular service is available in the region or configuration you need. |
| Security and compliance | Service-specific assurance and audit scope, encryption and key controls, logging, incident notification, vulnerability handling and the customer’s responsibilities. | A provider’s certification does not establish that a customer’s specific deployment is compliant. |
| Environmental sustainability | Service- and region-specific disclosures, their reporting boundaries and methods, and information on electricity, water and hardware lifecycle. | Metrics are only comparable when they cover similar services and use comparable methods. |
Check jurisdiction, data handling and operational control separately
Ask providers to identify the legal entity you would contract with and explain the relevant governing law and government-access process. Review the contract language on requests for customer information and the provider’s stated response commitments. For example, AWS publishes EU data-protection terms and says it will challenge overbroad law-enforcement requests where it has appropriate grounds. That is AWS’s stated position, not a general legal conclusion about any provider or deployment.
For data handling, make a data inventory before relying on a residency setting. Include content and copies, but also metadata, logs, support records, telemetry and AI-related inputs and outputs. Establish which locations apply to each service and data type, whether the commitment is regional or broader, and whether the customer can configure it. AWS describes residency and metadata controls for its European Sovereign Cloud; confirm the current service scope and contract rather than assuming the same controls apply across every AWS offer.

Evaluate resilience, security and service fit at the service level
Compare the services your workload will actually use, not broad provider catalogue claims. The Commission’s procurement emphasized fully managed services (PaaS), developer experience and automation. OVHcloud’s public catalogue, for example, includes compute, storage, networking, managed Kubernetes, managed databases and analytics; check the target-region documentation for the specific services you need. The procurement’s emphasis and a catalogue listing do not establish equivalence with another provider’s implementation.

For resilience, record the exact region and availability-zone design, inter-zone dependencies, disaster-recovery options, recovery objectives and support escalation path. Read the service-level agreement for the specific service, including exclusions and measurement rules. A provider-wide headline SLA is not directly comparable with a service-specific contractual commitment.
For security, compare audit scope and service coverage rather than collecting certification names alone. Establish encryption options, key ownership and administration, available logs, incident-notification terms and vulnerability-response processes. AWS describes a shared-responsibility model: customers must assess which security and compliance tasks remain theirs for the services and configuration they choose.

Compare the European procurement shortlist with the hyperscalers
The European Commission’s April 2026 sovereign-cloud procurement provides a current, concrete group of European offers to investigate. Eligibility required SEAL-2. The Commission reported the following qualification results for that procurement:
| Provider group named by the Commission | Reported SEAL level | What the result establishes |
|---|---|---|
| Post Telecom with CleverCloud and OVHcloud | SEAL-3 | Qualification for the Commission procurement scope. |
| STACKIT | SEAL-3 | Qualification for the Commission procurement scope. |
| Scaleway | SEAL-3 | Qualification for the Commission procurement scope. |
| Proximus/S3NS | SEAL-2 | Qualification at the required level for the Commission procurement scope. |
The Commission describes SEAL-3 as a digital-resilience level intended to address disruption from non-EU third parties. These procurement results are useful evidence for the named scope; they are not a universal ranking, a guarantee that every service in a provider group meets every requirement, or proof of price or service equivalence to AWS, Azure or Google Cloud.
Best Value
- Secure private cloud - Enjoy 100% data ownership and multi-platform access from anywhere
- Easy sharing and syncing - Safely access and share files and media from anywhere, and keep clients, colleagues and collaborators on the same page
- Automated Backup Protection - Set-and-forget backups for Macs, PCs and mobile devices to multiple destinations including cloud and external drives
- Home Security System - Record and monitor your property 24/7 with support for multiple IP cameras and remote viewing
- 2-Year Warranty - Reliable hardware backed by Synology's expert customer support team and ongoing software updates
Keep the hyperscalers in the shortlist when a required managed service, regional presence or integration with an existing technology estate makes them relevant. The Commission’s 25 June 2026 release called AWS and Azure the largest and second-largest cloud computing services in the EU, respectively, in a preliminary DMA position. That position was preliminary, not a final designation. Google Cloud remains a relevant comparator under the same workload-specific criteria; the cited Commission statement does not rank it in that passage.
Model total cost and the path in and out
There is no universal cheapest provider established by the available evidence, and no controlled workload benchmark here supports a general performance ranking. Build a like-for-like estimate for the services and regions you would actually use, over a realistic period. Include:
- Compute, storage, snapshots and managed-service charges.
- Network ingress and egress, inter-zone traffic and other data-transfer charges.
- Support plans, discounts, taxes and currency assumptions.
- Migration work, application changes, training and operational tooling.
- Export, transfer and transition costs if the workload later leaves the provider.
Ask each provider to price the same architecture and assumptions, then verify how the estimate changes with demand, data growth and recovery requirements. Map dependencies on proprietary managed services and estimate the work needed to replace them. Portability is an architectural and contractual question as well as a price question: establish data-export formats, practical transfer limits, access to backups and the assistance available at termination.

Turn the comparison into a defensible shortlist
- Define workload requirements. Record service capabilities, data types, required regions, recovery objectives, operational controls and compliance obligations.
- Set pass-or-fail gates. Identify non-negotiable contract, location, control, security and resilience requirements before scoring providers.
- Request the same evidence from each provider. Ask for the region-specific service list, architecture constraints, service-level agreement, support plan, compliance scope, subprocessors, data and metadata commitments, request-handling terms, recovery design and exit costs.
- Validate the proposed design. Confirm service availability and dependencies in the target region, and test recovery and operational procedures against the workload’s objectives.
- Compare lifecycle cost and migration burden. Use a common workload model, include egress and exit, and document where managed services create provider-specific dependencies.
- Record the reason for the decision. Keep the workload assumptions, supporting contract and service evidence, unresolved risks and trade-offs with the shortlist.
What current European cloud policy does—and does not—tell buyers
The Commission set a ceiling of up to €180 million over six years for its 2026 sovereign-cloud procurement framework for Union entities. That is the framework’s ceiling and duration, not evidence of actual spending, a market-size estimate or a price for cloud service.
In a 25 June 2026 release, the Commission said that over half of EU businesses rely on cloud services; the passage does not provide a survey methodology. Separately, its Cloud and AI Development Act policy page describes an objective to at least triple EU data-centre capacity within the next five to seven years. That is a policy objective, not a measured outcome. Neither statement substitutes for service-level evidence about a shortlisted provider.
