Data and the cloud are at once infrastructure, a market and a cross-cutting skill: every sector depends on them, but few organisations yet know how to use them well.
5.1The macroeconomic order of magnitude
- Cloud: about $850 billion of public cloud spending in 2026 according to Gartner, heading beyond a trillion within the decade.
- Data analytics: a global market of around $450 billion in 2026, with strong growth.
- The European data economy: about €500 to 550 billion, nearly 4% of EU GDP.
- The AI engine: nearly a fifth of cloud spending is already linked to AI.

5.2Jobs: a field short of talent
- Technical: data analyst, data engineer, data scientist, cloud architect, DevOps, platform engineer, FinOps.
- Governance: data steward, DPO, data governance lead.
- Public policy: open data, government data administration, GDPR, Data Act, the state's cloud strategy.
5.3Opportunities by sector
- Health: EHDS, Health Data Hub, personalised medicine under sovereignty constraints.
- Public sector: open data, digitisation, proactive administration.
- Industry 4.0: sensors, digital twins, predictive maintenance.
- Finance, marketing, retail: customer insight, fraud, pricing.
- Environment: satellite data, energy optimisation.
5.4Who captures the value?
- Hyperscalers: the toll booths of the digital world.
- Data SaaS: turning infrastructure into use.
- Consulting and integration: supporting adoption.
- FinOps: reducing and steering exploding spending.
- Sovereign: SecNumCloud and migrating sensitive data.
Key takeaway for entrepreneurs
Defensible value does not lie in off-the-shelf technology, but in proprietary data, domain integration and compliance. Two opportunities: simplifying GDPR/Data Act/NIS2 for SMEs and supporting sovereign migration.
