The cloud market in Spain is steadily advancing toward its consolidation as a strategic pillar of the digital economy. According to the report Cloud Nation 2025 produced by Grupo Aire, it is estimated that the sector will reach a business volume exceeding $22.5 billion (approximately €20.568 billion) by 2029, driven by digital transformation, the adoption of artificial intelligence, and the need for new data infrastructures.
The study highlights that growth will be sustained, with a compound annual growth rate (CAGR) of 13.7% in public cloud until 2026. Despite this positive outlook, the current penetration is still modest: only 31.65% of Spanish companies utilize cloud services, and half of them host less than 25% of their data in public clouds.
“Spain has everything it needs to be a digital powerhouse in Europe, but structural barriers still persist that we must overcome,” emphasizes Raúl Aledo, CEO of Grupo Aire. “The cloud is already an essential condition for business competitiveness.”

Barriers to Adoption
The report identifies the main obstacles to cloud migration in Spain:
- Regulation and Compliance: 58% of companies believe that regulations such as GDPR, the AI Act, or the NIS2 Directive act as a hindrance.
- Hidden Costs and Migration: 46% fear the costs associated with the transition.
- Security and Privacy: 42% express concerns regarding data management.
- Lack of Talent: The scarcity of technical and specialized profiles remains a critical challenge.
Additionally, the report highlights that only large companies (over 250 employees) account for 96% of public cloud demand, underscoring a gap between the business fabric and available solutions.
Towards a Hybrid and Decentralized Model
One of the key findings is that the future of cloud will not be exclusive. Organizations will combine on-premise infrastructures, edge computing, and cloud services to develop more flexible environments. This hybrid approach will better address the demand for low latency, security, and data sovereignty.
David Carrero, co-founder of Stackscale — a Grupo Aire company specialized in cloud infrastructure — points out: “Spain, and especially Madrid, has the potential to become a strategic hub for data centers. Moreover, Europe needs to position itself against the global competition coming with AI and robotics.”
An Emerging Hub in Southern Europe
The Iberian Peninsula already has 872 MW of installed capacity in data centers, with an occupancy rate of 29%, indicating room for expansion. Madrid leads this growth with 32 operational data centers, followed by Barcelona, which is still in the development phase but has clear growth prospects thanks to new infrastructures such as submarine cable stations and digital hubs.
In Summary
The cloud is establishing itself as a key enabler for the modernization of businesses and public administrations. The Grupo Aire report underscores that although adoption in Spain is still limited compared to the European average, the potential for growth is enormous. To achieve this, it will be necessary to invest in talent, flexibility, connectivity, and public policies that facilitate the digital transition.
Spain is on the verge of becoming a true ‘Cloud Nation.’ The time to accelerate is now.
