Cloud computing has moved from a cost-saving option to the default way businesses build and run software. Spending on it now runs into the hundreds of billions of dollars a year, and the market shows no sign of slowing.

The numbers point in two directions at once. Cloud adoption and spending keep increasing, while the hardest problems have shifted away from whether to move to the cloud and toward managing its cost, complexity, and security. Both sides matter, whether you are buying your first platform or optimizing a large estate.

To see where cloud computing really stands in 2026, it helps to read the market forecasts from research firms alongside the on-the-ground signal from buyers. On G2, 190+ products compete in the Cloud Platform as a Service (PaaS) category, and their reviews show how teams actually adopt and rate these tools. The statistics below pull both together, and each figure is sourced to the organization that produced it.

In this piece, I pull together the cloud computing statistics that matter most in 2026, grouped by how fast adoption is growing, what the market looks like, who is winning, where data lives, and what review data says about the tools themselves.

Now let us go deeper into each area and what the figures actually signify.

How I researched cloud computing statistics

To keep this list accurate and current, I combined primary research from the organizations that produce these numbers with G2's own review data.

  • Primary research sources: Figures come directly from Gartner, Synergy Research Group, the Flexera 2026 State of the Cloud Report, the Thales 2025 Cloud Security Study, IDC, Mordor Intelligence, the International Energy Agency, the Cloud Native Computing Foundation, Wiz, McKinsey, and the quarterly earnings of Amazon and Microsoft.
  • G2 review data: Adoption, ROI, satisfaction, and feature scores come from G2's 2026 Summer Grid Report for Cloud Platform as a Service (PaaS), using the Average row.
  • Verification: Every external figure was checked on a publicly accessible page from the source that produced it. Where a number sat behind a paywall or was only restated by an aggregator, it was replaced with a verifiable primary source or dropped.
  • Date range: All sources were published between 2025 and 2026.

How fast is cloud adoption growing in 2026?

Cloud adoption keeps climbing in 2026, but it is now close to saturation. The overwhelming majority of organizations build with cloud-native methods by default, and public cloud has become the home for the bulk of enterprise and small-business workloads alike. With adoption near its ceiling, the advantage no longer comes from being in the cloud; it comes from moving more of the estate there and running it well.

  • Public cloud workloads have continued to rise, growing year over year from 52% to 54% at enterprises and from 55% to 63% at small and midsize businesses, according to Flexera.
  • The Cloud Native Computing Foundation reports that 98% of organizations have now adopted cloud-native techniques, a sign of how deeply cloud is embedded in how software gets built.

What G2 reviews reveal: Adoption spans every company size. Among reviewers of Cloud Platform as a Service products on G2, 48% come from small businesses, 26% from mid-market companies, and 26% from enterprises.

Is cloud computing worth the investment?

For most buyers, yes. Reviewers report that cloud platforms recoup their cost quickly and keep customers satisfied, and independent analysis links disciplined cloud operations to substantial financial value over the rest of the decade.

What G2 Data reveals: The economics hold up and satisfaction runs high. On average, the Cloud Platform as a Service products buyers review give a return on investment (ROI) in about 13 months and earn a 63 Net Promoter Score, with 90% of reviewers saying their product meets requirements, 88% recommending it, 89% finding it easy to use, 90% feeling it is heading in the right direction, and 66% average user adoption.

Those returns line up with broader analysis. McKinsey estimates that cloud could represent $3 trillion in EBITDA value by 2030 and that leading enterprises can capture 60 to 70 percent of their desired financial goals when they pair cloud migration with strong operating practices.

How big is the cloud computing market?

Cloud computing is one of the largest and fastest-growing segments in technology. Worldwide public cloud spending already runs into the hundreds of billions of dollars a year and keeps growing at a double-digit pace, on a path toward the trillion-dollar-plus range before the end of the decade. Its pull is reshaping the wider technology budget along with it.

  • According to Gartner, worldwide end-user spending on public cloud services reached $723.4 billion in 2025, up from $595.7 billion in 2024, a 21.5% increase.
  • Gartner expects public cloud services spending to grow another 21.3% in 2026 and the market to reach $1.48 trillion by 2029.
  • Cloud is also reshaping wider technology budgets. Gartner projects worldwide IT spending of $6.31 trillion in 2026, with data center systems the fastest-growing segment as hyperscalers expand.

Who is winning the cloud computing market?

Three hyperscalers are winning the cloud market. Amazon, Microsoft, and Google together control roughly two-thirds of all cloud infrastructure spending, with AWS still in front, Microsoft second, and Google third. The rest of the field stays fragmented, though AI demand is starting to lift newer specialist providers toward the top tier.

  • Synergy Research Group reports that cloud infrastructure service revenue reached $419 billion for full-year 2025, including $119.1 billion in the fourth quarter, a 30% year-over-year increase and the ninth straight quarter of accelerating growth.
  • By provider, Synergy puts AWS at 28% of the market, Microsoft at 21%, and Google at 14%, with the three together holding 68% of public cloud. CoreWeave has emerged as a top-ten provider on the strength of AI demand.
  • The earnings back this up. Amazon reported AWS revenue reached $128.7 billion in 2025, up 20% year over year, with fourth-quarter AWS revenue of $35.6 billion growing 24%.
  • Microsoft reported that Azure and other cloud services revenue grew 39% in the quarter ended December 31, 2025.

What do public cloud statistics show?

Public cloud statistics point to a clear trajectory: both spending and data keep moving there. More than a quarter of organizations plan to increase their public cloud spend in the coming year, most now keep data in public cloud, and a meaningful share overrun their budgets along the way.

  • Data is concentrating in public cloud, with 61% of small and midsize businesses and 51% of enterprises now keeping data there, according to Flexera.
  • Spending is set to climb further, with 27% of organizations expecting to increase their public cloud spend over the next year.
  • That growth is hard to contain: 17% of organizations report they exceeded their public cloud budget in the past year.

How are hybrid and multi-cloud strategies evolving?

Hybrid and multi-cloud strategies are now the default rather than the exception. The typical enterprise spreads its workloads across more than one public cloud provider and layers dozens of SaaS applications on top, while hybrid cloud keeps gaining ground among developers. The upside is flexibility; the cost is that every added environment brings its own billing, security, and governance to manage.

  • The Cloud Native Computing Foundation finds that hybrid cloud usage has risen to 32% across all developers in 2026, up from 22% in 2021, as teams balance performance, cost, and data residency.
  • Multi-cloud is now the norm at the enterprise level. According to Thales, the average enterprise relies on 2.1 public cloud providers, which adds flexibility but also complexity.
  • The sprawl extends to software, too. Thales finds the average enterprise now uses 85 SaaS applications, each adding to the data and identities spread across clouds.
  • Managing that mix has become a leading concern in its own right. Flexera reports that 73% of organizations name managing multi-cloud a top challenge, since each environment adds its own billing, security, and governance demands.

How much data is stored in the cloud?

The data living in the cloud is growing fast, and the market that stores it is on track to roughly triple over the next five years. Hyperscale object storage has reached a scale that is hard to picture, holding hundreds of trillions of items, even as the underlying storage hardware market grows more slowly. North America remains the largest region, and object storage the dominant type.

  • According to Mordor Intelligence, the cloud storage market is projected to grow from $179.26 billion in 2026 to $513.86 billion by 2031, a 23.44% CAGR, with North America the largest region at about 38% of revenue and object storage the leading type at roughly 46%.
  • On the hardware side, IDC reports that the worldwide external enterprise storage systems market generated about $8.0 billion in the third quarter of 2025, up 2.1% year over year, led by Dell Technologies at 22.7% share, followed by Huawei at 12.0% and NetApp at 9.4%.
  • The scale of cloud object storage is hard to picture. Amazon S3 alone now stores more than 500 trillion objects and handles over 200 million requests per second.

What G2 Data reveals: Storage is a strength of the platforms buyers use. Across G2's 2026 Grid Report, the storage feature scores 88% on average.

How fast is cloud data center capacity growing?

Cloud data center capacity is expanding rapidly, and hyperscalers are driving most of the growth. They already operate well over a thousand of the largest facilities and hold close to half of global capacity, a share set to keep rising through the end of the decade as enterprise on-premises shrinks. The spending behind the buildout is climbing faster than almost any other category of IT, and it is pushing data center energy use sharply higher.

Is Kubernetes the operating system for cloud computing?

In practice, yes. The large majority of container-using organizations now run Kubernetes in production, and the Cloud Native Computing Foundation describes it as the de facto operating system for AI. Most teams hosting generative AI models manage their inference workloads on it, and the barriers that remain are now cultural rather than technical.

  • The Cloud Native Computing Foundation reports that 82% of container-using organizations now run Kubernetes in production, up from 66% two years earlier, and describes Kubernetes as the de facto operating system for AI.
  • AI is moving onto that foundation. The same survey finds 66% of organizations hosting generative AI models use Kubernetes to manage some or all of their inference workloads, and the cloud-native developer population has grown to 15.6 million.
  • Model choice in the cloud is broadening too. Wiz reports that about 7% of organizations running self-hosted AI models now use models from DeepSeek, a sign of how quickly new entrants gain ground.
  • The remaining barriers are now organizational rather than technical, with 47% of CNCF respondents naming cultural change in the development team as their top challenge.

What are the biggest cloud security risks?

The biggest cloud security risk is unprotected sensitive data. More than half of everything stored in the cloud is now classified as sensitive, yet only a small fraction of organizations encrypt most of it, leaving a wide gap between the value of the data and the protection around it. Cloud assets have also become attackers' main target, and most breaches now begin with stolen or compromised credentials.

  • According to Thales, 54% of all data stored in the cloud is now classified as sensitive, up from 47% a year earlier, yet only 8% of organizations encrypt 80% or more of their cloud data.
  • Cloud assets are now the main target. Thales finds that four of the top five most-targeted assets are cloud-based, and 68% of attacks are access-based, involving stolen or compromised credentials.
  • Complexity compounds the risk, with 55% of organizations saying the cloud is harder to secure than on-premises environments, up from 51% a year earlier.

What G2 Data reveals: Security is also where buyers set a high bar. Across G2's 2026 Grid Report, the security feature averages 90%, among the highest-rated capabilities in the category, a reminder that teams expect strong protection built into the platforms they choose.

Why is managing cloud spend challenging?

Cloud spend is hard to manage because waste is climbing again and costs are fragmented across providers, services, and teams. A meaningful share of every cloud dollar is still wasted, and for several years running, controlling that spend has ranked as the single biggest cloud challenge, ahead of even security. The complexity of AI and a steady stream of new services are making the bill harder, not easier, to predict.

  • According to Flexera, organizations waste an estimated 29% of their cloud spend, the first increase after five years of decline, driven by the cost complexity of AI and new services.
  • For the fourth consecutive year, managing cloud spend is the top cloud challenge at 85%, ahead of security at 82% and managing software licenses at 78%, and 63% of organizations have now implemented FinOps practices.
  • Spending is closely tied to company size, with 69% of small and midsize businesses spending less than $50,000 per month on public cloud while 76% of large enterprises spend more than $5 million per month.
  • Teams are leaning on provider discounts to keep costs down, with 48% now using Google committed use discounts and 45% using AWS reserved instances.

What do these cloud statistics mean for you?

Cloud growth is not slowing, but the advantage has shifted. The market is larger than ever and consolidating toward a few hyperscalers, yet the companies that win in 2026 are the ones that control cost, secure their data, and run modern, cloud-native platforms well. That is why challenges like wasted spend, sensitive data, and management complexity now matter more than raw adoption.

On the tooling side, the bar is high. Buyers report strong satisfaction, a 63 average Net Promoter Score, and roughly 13-month payback on the cloud platforms they adopt.
