ISG Provider Lens™ Private Hybrid Cloud - Data Center Services - Managed Services - Midmarket - France 2025

A year of changes in regulations and unexpected developments with substantial new investments

The major trends in the hybrid cloud market in France are significant investments and strategic developments aimed at bolstering the country’s AI infrastructure. The AI Action Summit, held in February 2025 at the Grand Palais in Paris, gathered over 1,000 participants, including world leaders, researchers, investors and technology providers from around 30 countries. Co-chaired with India, the event discussed establishing sustainable AI solutions and standards that serve collective progress and the public interest. The summit focused on five themes: Public Service AI, Future of Work, Innovation and Culture, Trust in AI and Global Governance of AI. President Emmanuel Macron emphasized the need to enhance France’s competitiveness at the event. A series of significant investments was announced during
the AI Action Summit. The UAE unveiled plans to invest between €30 billion and €50 billion in a data center campus as part of an AI partnership agreement signed with France. Canada’s Brookfield Corporation also announced a €20 billion investment in AI infrastructure. These investments align with France’s broader strategy to attract substantial funding and become a leading player in AI on par with the U.S. and China.

Also, the EU AI Act entered into effect in January 2024, aiming to govern AI development, deployment and use within the EU. The EU AI Act adopts a risk-based approach, categorizing AI systems into unacceptable, high, limited and
minimal risk levels. Unacceptable AI systems that manipulate human behavior or exploit vulnerable groups are prohibited. High-risk AI applications must meet rigorous requirements for testing, documentation, transparency, data quality and human oversight. Limited risk systems require transparency obligations, requiring that users be informed when they interact with AI. By fostering innovation while safeguarding human rights, the EU AI Act seeks to create a trustworthy AI ecosystem that aligns with European values and protects citizens.

It seems that strict regulations, such as HDS (Hébergement de Données de Santé), SecNumCloud by ANSSI (Agence Nationale de la Sécurité des Systèmes d’Information), Trusted Cloud regulations and the EU AI Act, and the discussions around cloud sovereignty have helped France attract new investments to strengthen the IT market in France. Operating under such strict and complex regulations adds an overhead cost to enterprises but also creates jobs, technology innovation and new business opportunities.

In the Managed Services — Large Accounts quadrant, providers enhance service delivery and operational efficiency using AIOps, logs and events to identify automation opportunities for service provisioning and incident resolution. As AIOps technology evolves, providers show varying levels of expertise, with the most advanced using GenAI to search knowledge bases and assist analysts. GenAI is the most relevant trend in 2025, with AI agents capturing incident contexts to quickly suggest solutions or identify root causes. GenAI’s impact on analysts’ productivity is impressive, helping them understand and resolve new or complex requests. More providers have incorporated FinOps tools to manage and optimize operations. Hybrid cloud architecture offers flexibility and scalability but introduces complexities in data engineering, especially when using sovereign clouds. Nineteen providers qualified for this quadrant, with seven being Leaders.

In the Managed Services — Midmarket quadrant, providers focus on delivering efficient, high-availability solutions through standardized service offerings and AIOps-driven automation. Providers most successful in this quadrant adopt a client-centric approach, working closely to understand specific challenges and propose innovative solutions. These
service platforms typically provide self-service capabilities, standardized service catalogs and approval workflows, ensuring streamlined operations and reliability. Although demand for data sovereignty solutions is not high among
midmarket clients, providers still offer security, governance and compliance assessments to enhance client  relationships. Partnering with local hosting providers to ensure data residency in France reflects the preference for regional data management. Overall, efficient service delivery, strong client engagement and local hosting solutions position providers well in the midmarket. Seventeen providers qualified for this quadrant, with six being Leaders and one Rising Star.

In the Managed Hosting quadrant, ISG observes significant advancements and a strong focus on data sovereignty, leading to a preference for hosting services that ensure privacy protections and data residency. Mistral AI and LightOn are particularly prominent in France for enabling GenAI solutions that use data stored within local private data centers. Most managed hosting providers offer private cloud services, utilizing technologies such as Red Hat or VMware to create self-service catalogs for provisioning virtual machines, databases and other virtual appliances. Many
providers have expanded to include GPU as a service (GPUaaS) on dedicated and shared infrastructure, with some integrating Mistral AI for rapid LLM creation and training. With extensive access to LLM on private cloud facilities, companies can develop custom GenAI solutions in compliance with data privacy and sovereignty regulations. However,
enterprises still face challenges regarding AI costs and the selection of the most suitable LLM. Hybrid solutions that combine private and public clouds are increasingly popular, allowing companies to leverage both environments.
Twenty-three providers qualified for this quadrant, with eight being Leaders.

In the Colocation Services quadrant, ISG identified several companies investing heavily in AI infrastructure in France, aiming to match AI capabilities seen in the U.S. and China. Investors from the UAE and Canada announced significant investments in data center facilities. The demand for data centers in Europe surpasses supply, prompting
investments from colocation providers and hyperscalers. High-performance computing and AI-capable data centers are key focus areas, but they require high-density computing, which generates significant heat and demands liquid cooling — a feature that is unavailable in most conventional data centers. New facilities with increased power capacity conflict with zero-carbon emission goals. However, France’s favorable climate reduces heating and cooling needs, leading to lower energy consumption, and its abundant clean energy from nuclear plants provides a sustainable advantage. Integration with public clouds is also in high demand. Providers increasingly offer SDN solutions for scalable, on-demand connectivity to numerous cloud service providers and data centers. Sixteen providers qualified for this quadrant, with five being Leaders and one Rising Star.

In the AI-Ready Infrastructure Consulting quadrant, providers strategize optimal cloud architectures and ensure seamless deployment and management operations. Adopting cloud solutions for AI presents data privacy and cloud sovereignty challenges, with stringent regulations demanding robust data protection and compliance. Service providers manage AI complexity through data engineering, creating efficient data pipelines for extraction, transformation and loading (ETL) before feeding AI analytics and LLMs. Designing an efficient data pipeline is critical to enabling scalable AI and LLM and requires a deep understanding of the underlying technology. With more enterprises opting for hybrid arrangements that combine multiple public and private clouds, the complexity and security challenges grow exponentially, resulting in higher operating costs. AI and LLM services follow subscriptionbased and usage-based pricing models, which vary for training and inference activities. Service providers help clients optimize pricing and spending while ensuring data privacy, security and regulatory compliance. Twenty providers qualified for this quadrant, with eight being Leaders.
