For years, IT professionals have relied on the “Big 3” hyperscalers: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). While incredibly powerful, relying exclusively on these global giants presents significant challenges for enterprises, particularly regarding complex compliance hurdles related to European data privacy laws, unpredictable egress fees, and rigid vendor lock-in. As regulatory frameworks such as the General Data Protection Regulation (GDPR) and the newly applicable EU Data Act become more stringent, architects and IT managers are actively seeking sovereign alternatives.
Enter the European Big 3: OVHcloud, IONOS, and Scaleway. These aren’t just regional, scaled-down replicas; they are mature, enterprise-grade cloud providers with unique hardware innovations, aggressive open-source adoption, multiple data center locations, and absolute jurisdictional security. This blog explores their technical service offerings and how they stack up against the global hyperscalers, providing actionable insights for engineering teams navigating the complex landscape of modern cloud deployments.
The Big Three
OVHcloud: The Vertically Integrated Pioneer
OVHcloud is the largest European cloud provider, known for its high degree of vertical integration, building its own custom servers and using proprietary liquid cooling to drastically reduce power consumption. Rather than relying on proprietary technology, OVHcloud organizes its extensive catalog around four core areas: Bare Metal Cloud, Hosted Private Cloud, Public Cloud, and Web Hosting & Domains.
For platform engineers, OVHcloud excels in pure infrastructure. Powered natively by OpenStack, you can deploy unmodified Bare Metal Instances via API or Terraform. They also offer a highly mature, CNCF-compliant Managed Kubernetes Service that integrates with Managed Private Registries, Managed Databases, and S3-compatible Object Storage. Furthermore, their “Bare Metal Pod” environment has achieved the rigorous SecNumCloud 3.2 certification, making it an elite, trusted environment for hosting highly sensitive enterprise or public sector workloads. They have data centers across Europe, North and South America, and the APAC region, and are expanding into the Middle East, so a wide variety of locations are available.
IONOS: The Enabler of the Software-Defined Enterprise
IONOS Cloud is designed specifically to meet the stringent compliance, security, and reliability requirements of B2B enterprises. With geo-redundant data centers across Europe and the U.S., IONOS offers a comprehensive suite of cloud services, including Compute Engine (IaaS), Object Storage, Managed Kubernetes, Apache Kafka, and Managed Databases.
Their standout feature is the Data Center Designer (DCD). Instead of locking developers into rigid VM sizes, this visual drag-and-drop tool—which is also fully automatable via their API and Terraform Provider—allows you to custom-build your Software-Defined Data Center. You can assign vCPUs, RAM, and storage with granular precision, and perform “live vertical scaling” to inject resources into running applications without requiring a system reboot. They also natively integrate Acronis Cloud Backup for seamless disaster recovery and offer an AI Model Hub for secure, open-source AI deployment.
Scaleway: The Innovation-Driven Challenger
Scaleway is a comprehensive cloud ecosystem designed for modern developers and distributed architectures. It is recognized for its strong commitment to environmental stewardship, operating data centers entirely on renewable energy with a highly efficient Power Usage Effectiveness (PUE).
Their product portfolio is extensive, encompassing Elastic Metal, serverless containers, managed Kubernetes, block storage, and seamless NATS integration for distributed messaging queues. Scaleway stands out globally for its silicon diversity. They offer Apple Silicon Mac mini instances for CI/CD pipelines and were the first cloud provider to offer open-standard RISC-V servers. For AI workloads, they operate an extensive array of NVIDIA GPUs, ranging from cost-effective L4s to massive, bare-metal H100 SXM clusters interconnected via NVLink. This enables massive Large Language Models (LLMs) to be trained securely within sovereign European borders. They offer availability zones in Paris, Amsterdam, Warsaw, and Milan, ensuring a broad presence across Europe.
The Trade-Offs: Where the Global Hyperscalers Still Reign Supreme
While migrating away from global hyperscalers is an attractive option, it involves specific architectural trade-offs.
First, the European Big 3 lack the sheer breadth of highly specialized Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) offerings. If your core application logic relies heavily on proprietary tools like AWS Kinesis for streaming or Azure IoT Hub, refactoring these to use open-source equivalents on a European cloud requires significant engineering time. Second, while OVHcloud, IONOS, and Scaleway maintain excellent European and North American infrastructure footprints, they cannot match the hyperscalers’ hyper-local edge availability zones in remote, emerging markets in Asia or South America. Finally, the capital expenditure (Capex) gap is vast; US hyperscalers invest hundreds of billions annually, giving them unparalleled speed in deploying the very latest hardware globally at maximum scale.
The Advantages: Avoiding Vendor Lock-in and Ensuring Data Sovereignty
The advantages of European providers are most evident in operational predictability, open ecosystems, and legal certainty.
The most critical financial factor for DevOps engineers is egress costs—the fees charged when data leaves the provider’s network. AWS, Azure, and GCP strictly meter and heavily penalize data movement, charging up to €0.10 per GB for internet egress, which can financially cripple data-intensive applications. In sharp contrast, European providers with a background in unmetered hosting offer significantly cheaper bandwidth. Scaleway, for example, offers transparent pricing with absolutely no egress fees for critical infrastructure traffic such as Object Storage or Kubernetes.
Furthermore, by building their clouds on open standards such as OpenStack and CNCF-certified Kubernetes, the European Big 3 actively eliminate vendor lock-in. Your code remains portable, allowing infrastructure to be seamlessly automated using standard declarative IaC workflows. Finally, these providers offer a crucial advantage in digital sovereignty. By natively utilizing European companies, you ensure that your data and infrastructure remain physically and legally within the EU, protecting your operations from foreign jurisdictional overreach—and thus from foreign governments forcing providers to hand over data even when it is stored within a European data center.
Why Digital Sovereignty Is Non-Negotiable
Digital sovereignty is no longer just a political talking point; it is a strict, board-level operational requirement. The core issue is a direct, unavoidable jurisdictional conflict. The 2018 U.S. CLOUD Act allows U.S. federal law enforcement agencies to unilaterally compel American cloud companies to hand over data, even if it belongs to European citizens and is stored on physical servers located within the EU.
This creates a massive compliance risk under GDPR Article 48, which prohibits the transfer of personal data to non-EU authorities. The situation became irreversible in September 2025 when the EU Data Act took full effect. The EU Data Act explicitly requires cloud providers to block unlawful access by third-country governments. U.S. providers operating in Europe are now caught between a rock and a hard place: complying with the U.S. CLOUD Act violates the EU Data Act, and vice versa. For European IT architects handling intellectual property or public sector workloads, storing sensitive data natively on OVHcloud, IONOS, or Scaleway is the only guaranteed architectural solution to remain legally immune from extraterritorial US overreach.
Conclusion
The global cloud computing landscape is undergoing a fundamental shift. While AWS, Azure, and GCP offer massive scale and thousands of specialized Managed Services, the hidden long-term costs associated with exorbitant egress fees, rigid vendor lock-in, and insurmountable legal conflicts regarding data privacy are driving a massive shift among enterprises.
OVHcloud offers unmatched bare-metal performance and elite SecNumCloud security, IONOS delivers enterprise agility with its live-scaling software-defined infrastructure, and Scaleway leads the way in ecological sustainability and sovereign AI computing power. As security regulations intensify, organizations must carefully consider the use of European-based cloud infrastructure, particularly in light of strict compliance frameworks such as the NIS2 directive and its local implementations, including the upcoming Cyber Security Act in the Netherlands.
