Power Sovereign Cloud Transformation with OVHcloud

As digital services become more critical and regulated, organizations need cloud solutions that combine performance with sovereignty. That’s why Sopra Steria partners with OVHcloud to deliver the Trusted Digital Platform—a secure, scalable, and fully European cloud infrastructure. Designed for sensitive workloads and vital industries, this partnership empowers clients to modernize with confidence while meeting the highest standards of compliance, security, and sustainability. 

As digital services expand and regulations tighten, organizations face growing pressure to modernize securely—without compromising control or compliance.

 

  • Data sovereignty requirements – Need to ensure data is stored, processed, and governed within European jurisdictions 
  • Security and compliance risks – Increasing demand for certified infrastructure (e.g., SecNumCloud, HDS, PCI-DSS) 
  • Legacy infrastructure limitations – Difficulty scaling or modernizing without disrupting critical services 
  • Vendor lock-in concerns – Dependence on hyperscalers with limited transparency or flexibility 
  • Sector-specific constraints – Public sector, healthcare, and energy clients require tailored, certified environments 
  • Sustainability expectations – Growing need for low-carbon, energy-efficient digital infrastructure 
  • Digital autonomy goals – Strategic push for European control over cloud infrastructure and data flows 

By addressing these challenges, we help clients build secure, sovereign, and future-ready digital foundations.

 

  • Trusted Digital Platform (TDP) – A sovereign cloud environment certified for sensitive workloads (SecNumCloud, HDS, PCI-DSS) 
  • End-to-end service delivery – From advisory and architecture to deployment and managed services 
  • Sector-specific solutions – Designed for public administration, healthcare, energy, and finance 
  • SAP S/4HANA readiness – Proven deployments on certified infrastructure 
  • Eco-responsible infrastructure – Low-carbon, energy-efficient data centers hosted in Europe 
  • Open Trusted Cloud label – Ensures transparency, interoperability, and vendor neutrality 
  • Joint innovation – Co-developed use cases in urban planning, sovereign data hubs, and secure digital services 

Together, we help clients build resilient digital ecosystems that meet the highest standards of trust, performance, and compliance. 

 

  • Full data sovereignty – Ensures compliance with European regulations and sector-specific mandates 
  • Reduced risk exposure – Certified infrastructure minimizes security and compliance vulnerabilities 
  • Faster time-to-deployment – Accelerates modernization of legacy systems and launch of new services 
  • Lower total cost of ownership – Optimized infrastructure and managed services reduce operational overhead 
  • Improved service continuity – High availability and resilience for mission-critical applications 
  • Sustainable IT operations – Energy-efficient infrastructure supports environmental goals 
  • Scalable innovation – Ready to support AI, data, and IoT use cases across industries

Sopra Steria & OVHcloud build trust for their customers’ move to the cloud – Yves Nicolas, Deputy CTO, Sopra Steria Group
What does cloud mean to you ? Three things : Feature richness, flexibility, and scalability. I often say that you cannot get on-premise today what you can get on the cloud. I take the example often of denial of service. You take that for granted when you take your cloud services. If you try to do that on-premise, that requires a lot of work. Flexibility is that you want a service, you get it in the cloud. So it's the perfect match when you work in agile mode. And scalability, the fact that the cloud services and resources will adapt to your customers, to the actual usage of your service. That's it. So feature richness, flexibility, scalability.

Digital trust is a big challenge. And digital trust, you need to address that both on the application level and in the data level. Application, to be able to move business-critical applications in the cloud. And data trust, so that you can be secure and sovereign on your data.

We have been working with OVHcloud in the last two years on working on these trusted services. And the result is an ecosystem of services around what we call the trusted digital platform. Which helps us, together with OVHcloud, propose to our customers to both take advantage of the cloud services with flexibility, scalability, while meeting their requirements on security and sovereignty. And I'm talking not about services which are going to be available in six months. I'm talking about services you can buy today.

Well, at Sopra Steria, our business is to help our customers design, deploy, and maintain their digital services. And for that, cloud services are essential. But our customers, they also need some security and sovereignty. And OVHcloud is key because it's the only partner that we have that can end all both, which is the feature richness and scalability you get in the cloud, together with the secure and the digital trust.

I would probably say artificial intelligence. And the reason is, artificial intelligence is both things that you can do today. When you take computer vision, prediction on time series, or natural language processing, you can bring value today. At the same time, we have key challenges to be able to deploy that at scale with our customers. And once again, together with OVHcloud, we have been working on designing new services and a complete roadmap on AI. Where we can bring our customers these services that enable them to deploy AI at scale in a trustworthy environment.
