1.1The questions this part answers

Key questions

  • Where is cloud risk concentrated?
  • Which couplings carry cloud shocks into other systems?
  • Which cloud capabilities hold under compound stress?
  • What must 2027 evidence measure first?

1.2The argument

Cloud computing is usually discussed as a service. The 2026 evidence reads it as shared infrastructure: facilities that draw electricity and reject heat, a few providers that carry much of the market, and a set of rules that are only now catching up11016.

The electricity evidence is clear in direction and uneven in method. Data centres used about 415 TWh in 20241, 4.4% of US electricity in 20233 and 22% of metered electricity in Ireland in 20244. Operators report efficient fleets, but their baselines differ57.

The market evidence is concentrated. Three providers held 63% of cloud infrastructure revenue in the second quarter of 202610. Competition authorities in the UK and EU have opened cloud reviews1112, and the Data Act removes switching charges in January 202716.

The resilience evidence comes from operators. One regional fault disrupted AWS services for 14 hours 32 minutes in 202520; a policy data error and a configuration file fault caused two other large events2122. Dependence of public services is not measured.

Figure 1.1Who holds the cloud infrastructure market? Share of revenue, Q2 2026, percent

Three providers hold about two thirds of cloud infrastructure revenue, and the analyst reports that the market grew 43% in a year. The shares cover infrastructure and platform services and hosted private cloud, not all cloud revenue10.

1.3Twenty couplings between five systems

The cloud-centred matrix types the twenty couplings between the five core systems, read for their cloud content. Strengths are Nexus estimates (ESTIMATED) from the cited evidence and analogue events; they set the graph that 2027 evidence will test.

Figure 1.2Couplings between the five systems

Each line is one coupling from one system to another, drawn by the strength the edition assigns. Strengths are Nexus estimates from the cited evidence and analogue events.
