+# Cloud and CDN Adoption Among Large Organizations
+
+## Overview
+
+This dataset records which cloud, hosting and CDN providers were detected on the websites of 21,325 large organizations, with firmographic context for each: industry, employee band, country, locality and founding year.
+
+Nineteen providers are covered, each as its own column, because organizations commonly use several at once. 3,259 of them show more than one.
+
+Collected in August 2026. Infrastructure changes, so treat the data as a snapshot of that month rather than a current state.
+
+## Providers Covered
+
+| Provider | Organizations | Type |
+| -------- | ------------- | ---- |
+| Cloudflare | 12,634 | CDN and edge |
+| AWS | 3,080 | Cloud |
+| Azure | 1,790 | Cloud |
+| Amazon CloudFront | 1,621 | CDN |
+| Akamai | 1,528 | CDN |
+| Fastly | 804 | CDN |
+| OVH | 775 | Cloud and hosting |
+| Google Cloud | 549 | Cloud |
+| Amazon S3 | 457 | Storage and delivery |
+| Vercel | 446 | PaaS |
+| DigitalOcean | 429 | Cloud and hosting |
+| IBM Cloud | 296 | Cloud |
+| Rackspace | 184 | Cloud and hosting |
+| Netlify | 138 | PaaS |
+| Alibaba Cloud | 103 | Cloud |
+| Huawei Cloud | 71 | Cloud |
+| Linode | 49 | Cloud and hosting |
+| Hetzner | 39 | Cloud and hosting |
+| Tencent Cloud | 1 | Cloud |
+
+## What the Data Shows
+
+**Cloudflare sits in front of 59.2% of these organizations**, more than every other provider combined. 10,403 show Cloudflare and nothing else, which usually means the origin behind it could not be identified rather than that no other provider is in use.
+
+The most common combinations:
+
+| Combination | Organizations |
+| ----------- | ------------- |
+| Azure + Cloudflare | 604 |
+| AWS + Cloudflare | 409 |
+| AWS + Amazon CloudFront | 377 |
+| Amazon CloudFront + Cloudflare | 317 |
+| Amazon CloudFront + Amazon S3 | 296 |
+| Cloudflare + Fastly | 208 |
+| Akamai + Cloudflare | 176 |
+
+Azure appearing alongside Cloudflare more often than AWS does is the reverse of the global picture, where AWS is detected on far more sites.
+
+Among organizations showing one of the two, Azure's share varies more by country than any other split in the data:
+
+| Country | AWS | Azure | Azure share |
+| ------- | --- | ----- | ----------- |
+| Brazil | 75 | 146 | 66.1% |
+| Australia | 64 | 74 | 53.6% |
+| Canada | 90 | 72 | 44.4% |
+| United Kingdom | 182 | 119 | 39.5% |
+| United States | 1,514 | 569 | 27.3% |
+| India | 219 | 38 | 14.8% |
+
+Regional providers matter more than their totals suggest. Among the 409 organizations based in China, Alibaba Cloud is the leading cloud at 20.8%, ahead of AWS at 10.3%, and Huawei Cloud reaches 11.0%. Azure and Google Cloud reach 2.2% and 2.0% respectively. 32.0% of Chinese organizations use at least one domestic provider. This concentration is why the three are kept as separate columns: 85 of Alibaba Cloud's 103 organizations and 45 of Huawei Cloud's 71 are in China.
+
+By sector, Akamai is the clearest signal. It reaches 206 organizations in retail and 104 in financial services, placing second in both, while barely registering elsewhere.

+| `Provider Count` | int64 | 100.0% | How many of the 19 providers were detected on this organization |
+
+## Methodology
+
+Websites were analyzed in August 2026 for technical fingerprints associated with each provider. An organization is included when at least one of the nineteen providers was detected on its primary domain.
+
+The population is organizations with 5,001 or more employees for which company information could be resolved.
+
+## Important Notes
+
+* Each provider column is a floor, not a share. It counts organizations where that provider's fingerprints were found. Detection strength differs between providers, so dividing one column by another does not give market share and should not be reported as such.
+* Detection favours providers that identify themselves in headers, DNS or asset URLs. A provider used purely for internal systems, or fronted by a CDN, may not appear at all.
+* Only the primary domain was analyzed. Organizations of this size run many domains, and a single marketing site is a weak proxy for the infrastructure behind the business.
+* Provider counts are not exclusive. An organization behind Cloudflare with assets on CloudFront and an origin on Azure counts in all three columns, which is the intended behaviour.
+* A row showing only Cloudflare usually means the origin was hidden, not that no cloud is in use. Treat Cloudflare-only rows as unknown origin rather than as an absence.
+* Hetzner and Linode appear on fewer than 50 organizations each. They are kept as columns for completeness, not because the counts support analysis.
+* Alibaba Cloud, Huawei Cloud and Tencent Cloud are kept as separate columns despite low global counts, because they are regionally concentrated and folding them together would remove the only view of the Chinese market in this data.
+* Results represent observations made in August 2026.
+
+## Use Cases
+
+* Cloud and CDN concentration analysis
+* Vendor and supply chain risk research
+* Competitive and market research
+* Technographic segmentation
+* Data science and machine learning
