Cloud computing is what the business world long ago started calling a “no-brainer”. The numbers are more interesting than that, and more uneven.
It offers enhanced security and stability, helps cut costs, and gives companies greater flexibility. The latter comes in handy when you need to navigate the ever-changing terrain of doing business – which most companies appreciate.
Cloud services are taking the business world by storm and cloud adoption statistics tell the same story.
Here is a taste of what’s to come:
Incredible Cloud Adoption Stats (Editor’s Choice):
- Public cloud end-user spending reached $723.4 billion in 2025, up 21.5% in a single year.
- Gartner credits AI and generative AI demand as the main driver of that acceleration.
- 52.7% of EU enterprises used paid cloud services in 2025, up 7.4 points on 2023.
- 73% of organizations run a hybrid cloud, up three points year over year.
- 58% now use generative AI as a public cloud service, up eight points.
- AWS and Azure are neck and neck, with Azure ahead in enterprise and AWS still leading among SMBs.
- 94% of enterprises already used a cloud service back in 2019.
- Cost-cutting remains the most cited reason for adopting the cloud, at 61%.
The cloud is already a big deal and it’s only going to keep growing for the foreseeable future.
Fascinating Cloud Adoption Facts
A word on reading what follows. Cloud adoption figures come from surveys, market models and official statistics agencies, and those three things are not interchangeable. Each statistic below carries its source and year, and where the original source gave no year, it says so.
1. Public cloud spending reached $723.4 billion in 2025, and AI is the reason.
(Source: Gartner)
Gartner’s end-user spending series runs $563.6 billion in 2023, $595.7 billion in 2024, and $723.4 billion in 2025. That last step is 21.5% growth in a single year, well above the pace of the two before it.
What changed is the driver. Gartner now credits AI and generative AI infrastructure demand as the main force behind the acceleration, rather than the broad enterprise migration that explained earlier growth. Cloud application infrastructure services (PaaS) are forecast at $208.6 billion, up 21.6%, with SaaS approaching $300 billion. These are Gartner estimates and forecasts rather than audited market totals, and Gartner revises them between editions.

2. More than $1.3 trillion in IT spending was forecast to be affected by the cloud shift by 2022.
(Source: Gartner, dated forecast)
Gartner divided the affected market into four categories, with application software the largest shift: 36% of companies that had hosted software by other means had moved it to the cloud, projected to reach 40% by 2022. System infrastructure was the smallest portion at 13% in 2019. We could not confirm a current replacement figure against a live Gartner source, so this stays as a dated forecast rather than a present-tense fact.
3. Quarterly SaaS spending hit $20 billion in Q2 2018.
(Source: Synergy Research, Q2 2018)
That quarter also brought 37% year-on-year revenue growth for software vendors. Microsoft led with over 17% market share and 45% annual revenue growth, followed by Salesforce at nearly 13%.
4. 94% of enterprises were already using a cloud service.
(Source: RightScale/Flexera State of the Cloud, 2019)
In that survey, 91% used a public cloud and 72% a private one, with most using both. Only 22% used a private cloud alone. For a current read on how many companies have made the move, see how many companies use cloud computing.
5. 30% of all IT budgets went to cloud computing in 2018.
(Source: Forbes, 2018)
Roughly 48% of that went to SaaS, 30% to IaaS and 21% to PaaS. Companies with more than 1,000 employees spent an average of $3.5 million.
6. 66% of enterprises already had a central cloud team.
(Source: RightScale, year not stated)
A further 21% planned to create one. Their main responsibility was optimizing cloud costs, cited by 68% of enterprises. The original text gives no year, though it most likely comes from the same 2019 RightScale report cited above.
Cloud Adoption Among Enterprises
For clarity, “enterprises” here means companies with more than 1,000 employees, and “SMBs” those with fewer.
7. Cost-cutting is the top reason enterprises move to the cloud, at 61%.
(Source: Datometry, year not stated)
In a survey of 166 IT leaders, 61% cited cost, 57% wanted new features and capabilities, 30% were running out of warehouse capacity, and 23% cited an executive mandate. The sample is small and the original gives no fieldwork year.
8. 73% of organizations now run a hybrid cloud, and 58% use GenAI as a cloud service.
(Source: Flexera State of the Cloud, 2026)
Hybrid remains the dominant architecture, up three percentage points year over year. Separately, generative AI has climbed eight points to become the third most used public cloud service at 58% of respondents, with nearly half saying they use it extensively.
These are two distinct measures and should not be merged into one adoption figure. They do point the same way, though: the AI demand Gartner credits for the spending jump is showing up in what organizations say they actually run.
9. AWS and Azure are now neck and neck.
(Source: Flexera State of the Cloud, 2025)
This page used to describe AWS as the clear leader at 67% adoption with Azure trailing at 60%. That is no longer the picture. Flexera now describes the two as neck and neck, with Azure edging ahead in some tiers and in the enterprise segment specifically, while AWS remains dominant among smaller businesses.
The split matters if you are choosing a provider. Enterprise preference has moved toward Azure, helped by existing Microsoft licensing relationships, while AWS retains its lead where teams start from scratch without an incumbent vendor. Google Cloud remains a distant third in both segments.
Cloud Adoption Among SMBs
Smaller companies adapt faster but have less to spend, and managed cloud services let them run serious infrastructure without hiring for it. The figures in this section are dated and worth treating as historical.
10. 94% of SMBs reported security benefits after moving to the cloud.
(Source: Microsoft Office 365, year not stated)
The same research reported that 59% saw significant productivity benefits against 30% of those not yet in the cloud, 82% reported reduced costs, and 70% reinvested the savings. This comes from a vendor with an interest in the answer, and the original gives no year. Security is the usual reason small companies hesitate, which is worth weighing against our data breach statistics before assuming either direction is automatically safer.
11. 41% of SMBs favored the public cloud.
(Source: Flexera, 2019)
51% of SMBs spent less than $600,000 a year on cloud services. Their main workload ran in public clouds at 43% against private at 35%, the reverse of the enterprise pattern at the time.
12. AWS was the favorite SMB provider at 53% adoption.
(Source: Flexera, 2019)
VMware vSphere led private cloud adoption among small companies at 35%. Given the competitive shift described above, this SMB figure is dated and would need its own check, though AWS’s continued strength in this segment is consistent with the current reporting.
Cloud Adoption Among Government Organizations
Public sector adoption runs behind the private sector and leans more heavily on private cloud. Every figure in this section is undated in its original source.
13. 50% of US government organizations use the cloud.
(Source: Gartner, year not stated)
Efficient service delivery and cost savings are the two stated drivers. Gartner expected government public cloud spending to grow at an average of 17.1% per year.
14. Government organizations still favor the private cloud.
(Source: Macquarie Government, year not stated)
Between 20% and 40% of agency workload was already in the cloud, with investment in public cloud SaaS rising but private cloud remaining the preferred model, forecast to grow at twice the rate of public cloud.
15. 60% of government agencies use an internal team to handle migration.
(Source: Macquarie Government, year not stated)
The rest rely on an external provider. Of those that migrated, 44% said it went as expected, 20% found it easier, and 36% found it harder.
Cloud Adoption in Different Industries
Sectors move at different speeds, driven by different needs and regulatory constraints.
16. Manufacturing was projected to spend more than $5 billion on cloud in 2019.
(Source: Manufacturing.net, citing IDC, 2019)
The forecast was $5.18 billion, sustaining a 23% growth rate. IDC found discrete manufacturing was the biggest public cloud spender in 2018.
17. 70% of financial services companies were in the early stages of cloud adoption.
(Source: InformationAge, year not stated)
Around 70% described their cloud projects as still in trial and testing, while 60% expected a multi-cloud environment integrating on-premise and cloud. The sector combines cautious migration with clear long-term plans, largely because of regulatory requirements around where data sits.
Cloud Adoption in Different Countries
Adoption varies sharply by region, and the most reliable numbers here come from official statistics agencies rather than vendor surveys.
18. Only 2% of UK businesses had yet to use the cloud.
(Source: Computing, 2018)
88% of UK businesses were using cloud services in 2018, up from 85% in 2017, with a further 10% at the trial stage. No reliable current figure was found to update this, so it stays dated.
19. 52.7% of EU enterprises used paid cloud services in 2025.
(Source: Eurostat, 2025)
That is a 7.4 percentage point rise on 2023, when the figure was 45.3%. Email leads the use cases at 85.2% of cloud-using enterprises, followed by office software at 71.7% and file storage at 71.5%.
This is the most solid number on the page, because it comes from an official statistics agency surveying a defined population on a fixed schedule rather than from a vendor panel. It is also a useful corrective: after fifteen years of cloud being described as universal, barely half of EU enterprises pay for it.
20. Only 10% of Asia-Pacific businesses have yet to adopt the cloud.
(Source: 451 Research, year not stated)
More than 90% of businesses in the region use or plan to use a multi-cloud environment. Security dominates the decision: 95% call it important to hybrid cloud choices and 56% call it critically important.
Bottom Line
Cloud adoption is no longer the story. Where the spending goes next is. Public cloud spending grew 21.5% in 2025 to $723.4 billion, and Gartner attributes that jump to AI infrastructure demand rather than to the general migration that drove the previous decade. Flexera’s survey data agrees from the other direction: generative AI is now the third most used public cloud service.
The rest of the picture is more uneven than the marketing suggests. Barely half of EU enterprises pay for cloud services at all. Hybrid, not public cloud, is the dominant architecture at 73% of organizations. Government agencies still lean private. And the provider race that this page once described as settled in AWS’s favor is now genuinely close, splitting along enterprise and SMB lines.
If you are weighing a move, the useful comparisons are elsewhere on this site: cloud computing market size and trends for where the money is going, and remote work statistics for the distributed-team demand that pulled a lot of this infrastructure into place.
