Berlin / Milan, 8/7/2025
At a time when Europe’s digital sovereignty is under increasing geopolitical and economic pressure, the Sovereign European Cloud API (SECA API) initiative moves into its next decisive phase. As founding cloud providers Aruba, IONOS, and Dynamo have issued a public call to action, the message is clear: now is the time to build a truly open, interoperable cloud standard for Europe.
Interested parties can contribute on the further development of SECA until the middle of September. SECA API is a critical building block for Europe’s digital independence. Already widely covered by media and closely followed by industry stakeholders, the initiative has gained significant momentum across the continent. It serves as a foundational component of the emerging EuroStack, and has the potential to support and complement national efforts such as the Deutschland-Stack, and even re-energize ambitions under IPCEI-CIS.
By offering a modular, open interface for cloud infrastructure, SECA API aims to bring Europe’s fragmented cloud landscape towards a common denominator through real, testable interoperability — not just sovereignty in name.
Just weeks after its public launch, SECA API has now entered its “Participation & Interaction” phase with a formal Call for Comments (RFC) process open to all European cloud providers, software developers and engineers, and infrastructure stakeholders, as well as System Integrators and Business Consultants.
“SECA API is not a solo effort — and it was never meant to be,” wrote Achim Weiß, CEO of IONOS, in his public letter. “Let’s stop trying to compete with hyperscalers on their terms, and start leading on ours. If we don’t build it, someone else will – and it won’t be built on our terms.”
“Now is the time to continue shaping the future of cloud and embracing solutions rooted in European values. By opening the SECA API to public consultation, we are inviting the entire industry to help co-create and drive a truly European cloud which is built on collaboration and shared principles.” commented Stefano Cecconi, CEO of Aruba.
Europe’s weakness lies in fragmentation. Our providers have the skills, innovation, and capacity—but lack customers. Without bridging this gap, we can’t meet the growing demand of the common market. SECA offers a pragmatic path to interoperability among suppliers, building trust and enabling seamless integration. Dynamo supports SECA as it fosters a collaborative ecosystem where providers remain independent yet stronger together. We invite CSPs, ISVs, system integrators, and end users to help shape SECA into a widely adopted industry standard,
Francesco Bonfiglio CEO, Dynamo
What’s New in Phase 2: Call for Comments & RFC Framework
The launch of the SECA API RFC process gives the entire cloud community — from independent developers to
established providers — the opportunity to shape the API’s future development.
Participants can:
- Propose features, improvements or extensions via a public GitHub RFC repository
- Join working groups focused on interoperability, security, and governance
- Align technical innovation with EU regulations such as the Digital Markets Act, Data Act, and AI Act
- Contribute SDKs, CLI tools, and test frameworks for shared adoption
Join our first community call on 18 July 2025 at 2:00 p.m. CEST. Just drop an e-mail at info@secapi.cloud to get invited.
All contributions are transparent, consensus-based, and royalty-free.
This open RFC strategy positions SECA API to become Europe’s first collaboratively developed cloud interface standard, with technical integrity and regulatory readiness baked in from the start.
Why SECA API Matters — and Why Now
The SECA API initiative was launched to provide a real alternative to lock-in-heavy, and as a part of the process, an effective legal immunity from interference by extra-European countries that are governed by non-European laws. Built on OpenAPI and aligned with European legal and compliance frameworks, SECA API allows:
- Seamless interoperability across different providers and platforms
- Modular deployment (Control Plane + Data Plane)
- Faster adoption through integration with existing cloud stacks
- Clear separation of roles, enabling national or regional rollouts
The API is already available – with no licensing costs or proprietary constraints.
