How much revenue did Google Cloud earn?

Google Cloud earned $20.0 billion in Q1 2026, up 63% year over year, with operating income of $6.6 billion and cloud backlog above $460 billion. The segment spans Google Cloud Platform across enterprise AI Solutions and core GCP services, plus Workspace, which Alphabet flagged as a contributor to the acceleration alongside agentic AI workloads.

UK Cloud Computing Market Segments

• The UK public-sector cloud market is worth around £6 billion in 2024, according to the Department for Science, Innovation and Technology and the Government Digital Service.
• During the 2023-24 financial year, the amount of cloud spend transacted through the G-Cloud framework totalled £3.1 billion.
• The headline £3.1 billion transacted through G-Cloud against DSIT’s £6 billion UK public-sector cloud market implies that roughly half of UK government cloud spend reaches providers through routes other than the framework.
• G-Cloud 15 replaces G-Cloud 14 and its specialist Lot 4 for Cloud Compute services, integrating Cloud Compute into the main G-Cloud structure and launching in 2026 after a 23 October 2025 invitation to tender.
• The UK Cyber Security Breaches Survey 2025/2026 found 74% of UK businesses back up data securely via a cloud service, compared with 47% using two-factor authentication and 36% using a VPN for remote staff.
• The UK cybersecurity sector, much of it cloud-delivered, generated £13.2 billion in revenue and £7.8 billion in Gross Value Added in 2024, with a 12% revenue increase year over year and 67,300 jobs supported.
• AI-driven security solutions are now a core component in 52% of the solutions delivered by UK cybersecurity companies, with 14 specialist providers focused exclusively on AI security.

What percentage of UK businesses use cloud services?

The UK Cyber Security Breaches Survey 2025/2026 reports that 74% of UK businesses back up data securely via a cloud service, placing cloud backup ahead of two-factor authentication (47%) and VPNs for remote staff (36%) as a deployed control. The figure understates wider cloud usage, since survey items focus on security-relevant cloud workloads rather than productivity or compute consumption.

EU Cloud Adoption by Enterprise Size

• Eurostat reports 52.7% of EU enterprises used paid cloud computing services in 2025, a 7.4 percentage point increase compared with 2023, and a substantial rise from 17.8% in 2014.
• Adoption splits sharply by size: 84.67% of large enterprises, 66.78% of medium enterprises and 49.3% of small businesses used paid cloud services in 2025.
• The biggest accelerations between 2023 and 2025 happened in Lithuania (+19.7 pp), Italy (+14.2 pp) and France (+13.7 pp).
• Top use cases for EU cloud customers, where Microsoft 365 statistics anchor the productivity layer: e-mail services (85.2%), office software (71.7%) and file storage (71.5%), with security software at 65.5% and finance or accounting software at 58.2%.
• The highest national adoption rates sit at Finland (79.2%), Italy (75.6%) and Malta (74.9%); the lowest are Romania (24.9%), Greece (24.3%) and Bulgaria (17.8%).

Cloud Service Models: IaaS, PaaS, and SaaS Spend

• The Q1 2026 tracker notes that public IaaS and PaaS services grew by 38% in Q1, representing the bulk of overall cloud activity.
• Gartner expects public cloud services growth of 21.3% in 2026, on track to reach $1.48 trillion by 2029, with AI integration as a primary driver.
• Across machine learning and analytics workloads, Flexera found 81% of respondents use generative AI, up from 72% the prior year and 47% in 2024.
• Nearly half (45%) of respondents now use generative AI extensively, up from 36% in 2025, per Flexera’s 2026 survey.
• Hybrid environments dominate operational reality: 73% of organisations operate hybrid environments while multi-cloud adoption rises.
• Large-enterprise cloud bills have crossed the $5 million per month line for most respondents: more than three-quarters (76%) of large enterprises now spend over $5 million monthly on cloud services.

Public, Private, and Hybrid Cloud Usage

• Flexera’s 2026 survey of more than 750 cloud decision-makers found 73% running hybrid environments, with multi-cloud rising alongside.
• IBM’s breach economics underline the operational cost of the mix: public cloud incidents averaged $4.18 million in 2025, private cloud breaches $4.68 million, and breaches across multiple environments $5.05 million, the highest deployment category.
• Breaches that crossed cloud environments cost meaningfully more than pure public-cloud breaches in IBM’s 2025 sample, an operational tax for hybrid complexity that organisations are increasingly absorbing.
• Cloud governance investment is broad: 71% of organisations now operate a Cloud Center of Excellence (CCOE), up from prior survey years.
• 63% of organisations have established FinOps teams, and 64% report value delivered to business units as a top metric, per Flexera.
• The wasted-spend metric reversed direction: wasted cloud spend rose to 29% for the first time in five years, driven largely by cloud-based AI workload proliferation.

Key finding: Hybrid is the operating reality for 73% of cloud customers, yet wasted spend climbed to 29% in 2026, the first increase in five years, despite 71% having a Cloud Center of Excellence. The unifying variable is AI workloads, which over-provision compute and inflate sandbox sprawl faster than FinOps controls can compress them.

Cloud Security and Data Breach Costs

• IBM’s 2025 Cost of a Data Breach Report puts the global average breach cost at $4.44 million, down 9% from $4.88 million in 2024, with a mean containment time of 241 days.
• US companies broke higher: the US average breach cost jumped 9% to an all-time high of $10.22 million in 2025.
• Shadow AI is a measurable line item: unapproved AI tools add an extra $670,000 to the global average breach cost.
• ENISA’s 2025 Threat Landscape analyses 4,875 incidents from July 1, 2024, to June 30, 2025, with vulnerability exploitation, including misconfigurations and public-facing services, responsible for 21.3% of intrusion cases.
• ENISA flags abuse of misconfigurations and inadequate change control as a significant threat in cloud environments, alongside human error, malicious attack and negligence.
• Flexera puts security and compliance as the top challenge for cloud-based AI initiatives for more than half (53%) of cloud leaders, with data quality for AI model training at 40%.
• The UK Cyber Security Breaches Survey 2025/2026 finds 52% of UK cybersecurity vendor solutions now have AI as a core component, with 14 specialist providers focused exclusively on AI security.

How much does a cloud data breach cost on average?

Cloud breach economics depend on the deployment model. IBM’s 2025 report puts the average public cloud breach at $4.18 million, private cloud at $4.68 million, and multi-environment breaches at $5.05 million, the highest of any deployment category. The multi-environment top-out reflects the operational complexity of incident response across providers. US-specific breaches sit in a separate cost band regardless of cloud mix.

Neoclouds and Second-Tier Provider Growth

• The Q1 2026 tracker identifies CoreWeave, OpenAI, Oracle, Crusoe, Nebius, Anthropic and ByteDance among the highest-growth second-tier providers.
• Five neocloud companies are now among the top thirty cloud providers, with the segment already accounting for 5% of the total cloud market and a substantially larger share of AI-focused segments.
• Among neoclouds, CoreWeave represents by far the largest player in this market, while Crusoe, Nebius and Lambda are growing extremely rapidly, per the cloud tracker.
• John Dinsdale’s Q3 2025 commentary noted that third-placed Google remains nearly four times the size of fourth-placed Alibaba, framing the gulf between hyperscalers and the long tail even as neoclouds expand share.
• Geographies expanding well above worldwide cloud growth include India, Indonesia, Ireland, Taiwan, Thailand, and Malaysia, several of which host neocloud or hyperscaler regional capacity.

What is a neocloud provider?

A neocloud provider is a specialised cloud company focused on AI compute workloads rather than the full enterprise platform stack of AWS, Azure or Google Cloud. The Q1 2026 tracker identifies CoreWeave, Crusoe and Nebius alongside OpenAI’s and Anthropic’s compute footprints as the highest-growth examples, with five names entering the top thirty providers and collectively accounting for 5% of the cloud market.

AI-Driven Cloud Spend: Generative AI and FinOps Reality

• Flexera’s 2026 report tracks generative AI usage at 81% of respondents, up from 72% in 2025 and 47% in 2024.
• Extensive deployment is climbing: nearly half (45%) of organisations report using generative AI extensively, up from 36% in 2025.
• Microsoft disclosed its AI business surpassed an annual revenue run rate of $37 billion, up 123% year over year, a direct cloud-revenue line.
• Alphabet’s CEO highlighted that Gemini Enterprise has great momentum with 40% quarter on quarter growth in paid monthly active users.
• Google Cloud Next 2026 introduced the Gemini Enterprise Agent Platform, 8th Generation TPUs and access to more than 200 models in Model Garden, alongside an Agentic Defense integration with Wiz.
• Wasted cloud spend reversed years of FinOps discipline: wasted cloud spend rose to 29% for the first time in five years, with security and compliance flagged as the top AI challenge by 53% of cloud leaders.

Why it matters: AI workloads now run a top-of-mind cloud capability for 81% of enterprises while pushing wasted spend back to 29%, with Microsoft’s $37 billion AI run rate showing the revenue side of the same equation. The pattern fits a market where AI demand pulls capex faster than FinOps controls can compress it.

Sovereign Cloud and Regional Investment

• Gartner forecasts worldwide sovereign cloud infrastructure as a service spending of $80 billion in 2026, a 35.6% increase from 2025.
• Microsoft expanded its sovereign offering: Microsoft Sovereign Private Cloud scales to thousands of nodes via Azure Local, with in-country Microsoft 365 Copilot processing now available in the UK, Australia, India and Japan, expanding to eleven more countries in 2026.
• AWS shipped EC2 capacity in additional European and Asia-Pacific regions: EC2 M8in and M8ib launched in US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo), and Europe (Spain) with up to 600 Gbps networking.
• The Q1 2026 cloud tracker identified India, Indonesia, Ireland, Taiwan, Thailand, and Malaysia as the geographies expanding at rates well above the worldwide average.
• UK sovereign cloud arrangements stack on top of the public-cloud framework: the UK Government Cloud First policy requires central government departments to use public cloud services as the first choice when buying IT services.
• The Microsoft Cloud in the UK addresses data residency, encryption sovereignty, and operational independence from non-domestic operators, a baseline above which sovereign private cloud nodes layer.

Common Questions

Is hybrid cloud bigger than public cloud?

Hybrid cloud adoption is higher than pure public-cloud-only operation among large enterprises, but public cloud generates the largest market share in terms of spending. Flexera reports 73% of organisations operate hybrid environments, while the cloud market tracker shows public IaaS and PaaS specifically grew 38% in Q1 and now drive the bulk of cloud activity. The two figures answer different questions: deployment mix versus spending share.

Conclusion

Cloud computing this year matches the 2021 surge in growth shape, a $129 billion quarter, 35% YoY, 63% Big Three share; but the driver flipped to generative AI workloads from pandemic-era migration. Neoclouds led by CoreWeave have crossed the 5% mark for the first time.

The trade-offs are visible in the same data: wasted cloud spend at 29%, multi-environment breaches at $5.05 million, and security topping the AI risk list. UK and EU buyers continue to absorb those trade-offs because the per-workload economics still favour cloud-delivered technologies for AI inference and storage. The question for the next cycle is whether FinOps maturity catches up with AI capacity.
