Other major US providers include Oracle, IBM, Salesforce, VMware (Broadcom) and DigitalOcean.

Key Takeaways

• AWS is the market leader: Synergy Research Group put Amazon at 29% of the global cloud infrastructure market in Q3 2025, ahead of Microsoft (20%) and Google (13%).
• Eight of the ten companies below are US-headquartered. Alibaba Cloud and Tencent Cloud are Chinese companies and are listed for comparison only.
• VMware is no longer independent: Broadcom completed its US$69 billion acquisition of VMware on November 22, 2023.
• IBM Cloud and Kyndryl are different companies: Kyndryl was spun off from IBM in November 2021; IBM Cloud stayed with IBM.
• Figures change every quarter. Revenue, staff and region counts below carry the date of the source they come from.

Note (September 2026): This list was compiled in May 2023 and was re-checked in September 2026 against the companies’ own infrastructure pages, investor pages and Wikipedia summaries of their filings. Since then, Broadcom completed its acquisition of VMware in November 2023. Alibaba Cloud and Tencent Cloud are Chinese companies. Several 2023 statements were wrong or out of date (AWS staff and revenue, Salesforce’s headquarters, IBM Cloud being described as Kyndryl, and most region counts) and have been corrected in place.

The need for cloud computing has grown more than ever in the digital age. The way businesses keep, access, and share information has undergone substantial changes as a result.

Amazon Web Services (AWS)

The world’s largest cloud service provider is Amazon Web Services (AWS), the cloud computing arm of Amazon.com. The company offers over 200 fully featured services from its data centers, including computing, storage, and database.

As of September 2026, AWS lists 124 Availability Zones within 39 geographic Regions, and has announced 7 more Availability Zones and 2 more Regions in Saudi Arabia and Chile. These regions and availability zones can be found all around the world, including in the Middle East and Africa, AWS GovCloud (US), the Americas, Europe, and Asia Pacific.

With a wide range of offerings that include storage, computing, networking, databases, and AI/ML services, AWS has emerged as a top choice for many companies. The figure of 2 million employees that circulated for AWS was never an AWS number: Amazon as a whole, headquartered in Seattle, Washington, and Arlington County, Virginia, reported about 1,576,000 employees in 2025. AWS itself reported revenue of US$128.7 billion and operating income of US$45.6 billion in 2025.

Salesforce

Since its 1999 San Francisco founding, Salesforce, a cloud computing business, has experienced phenomenal growth. Salesforce has one headquarters: Salesforce Tower in San Francisco, California. For the fiscal year ended January 31, 2026, Salesforce reported revenue of US$41.5 billion and 83,334 employees, according to Wikipedia’s summary of its annual report.

Salesforce provides services like customer relationship management software product development, web-based software applications, and cloud computing solutions for both large and small businesses. Salesforce is one of the Cloud Computing companies driving the trend in the USA. With the adoption of its cloud-based technology in nations like Germany and India as well, its appeal has now gone global.

Google Cloud Platform

The third-largest global cloud service provider is Alphabet Inc.’s Google Cloud Platform (GCP), which offers cloud services that are suitable for businesses. GCP gives developers access to the service’s security, data management, analytics, and artificial intelligence (AI) capabilities as they test, build, and deploy apps on its scalable infrastructure.

As of September 2026, Google Cloud’s locations page lists 43 regions and 130 zones, with services available in more than 200 countries. These regions and availability zones are dispersed over the Americas, Europe, Asia Pacific, and the United States.

The Google Cloud division of Alphabet Inc. makes money by charging customers for its platform, infrastructure, and other services. The quarterly sales figure quoted when this article was first written in 2023 is now well out of date. For full-year 2025, the Google Cloud segment, which also includes Google Workspace, reported revenue of US$58.7 billion and operating income of US$13.9 billion.

VMware (now part of Broadcom)

VMware was founded on February 10, 1998, and is based in Palo Alto, California. Since November 22, 2023, it has been part of Broadcom, which bought it in a cash-and-stock deal valued at US$69 billion. VMware’s revenue was about US$13.4 billion in 2023, the last year it reported as an independent company. VMware had about 38,300 employees before the takeover and provides cloud, security, virtualization and automation software. Broadcom then laid off more than 2,800 employees and reorganized VMware into four divisions: VMware Cloud Foundation, Tanzu, Software-Defined Edge, and Application Networking and Security.

VMware’s cloud computing services are made to make it simpler for businesses to undergo digital transformation while also enhancing agility, lowering costs, and boosting security. With cutting-edge technology, VMware offers simple-to-use Cloud-based solutions that assist businesses in improving customer experiences, streamlining workforce processes, and remaining competitive in the current and future markets.

Alibaba Cloud

The cloud computing division of Alibaba Group, known as Alibaba Cloud, is the biggest cloud service provider in China, the main cloud vendor in the Asia Pacific, although it is a Chinese company (campus headquarters in Hangzhou, international business registered in Singapore), not a US one. The company provides cloud services through Alibaba Cloud, including elastic computing, big data analytics, machine learning, databases, storage, network virtualization, large-scale computing, security, management & application services, and elastic computing.

According to Wikipedia, Alibaba Cloud operates data centers in 29 regions and 87 availability zones around the world. Alibaba, which has more than 10 regions nationwide, is the leading cloud service provider in Mainland China. Alibaba Cloud operates outside of Mainland China in the Americas, Europe, Asia Pacific, and the Middle East.

IBM Cloud

IBM’s managed infrastructure services division was spun off as Kyndryl, a separate New York City-based company that began trading independently on November 4, 2021. Kyndryl designs, builds and manages infrastructure for clients, while IBM Cloud, the public and hybrid cloud platform built on IBM’s 2013 SoftLayer acquisition, remains part of IBM.

IBM Cloud is not part of Kyndryl. As of 2026, IBM states that its cloud infrastructure spans more than 60 data centers across 19 countries and six multizone regions. These regions and availability zones are dispersed over the Americas, Europe, Asia Pacific, and the United States.

By fusing services from private cloud service providers, internal platforms, and Internet of Things (IoT) technologies, Kyndryl’s Cloud Services division aids businesses in making the best use of cloud service providers.

Oracle Cloud

Oracle Cloud Software-as-a-Service (SaaS) and Oracle Cloud Infrastructure (OCI) are two of Oracle Corporation’s cloud service options. The business offers cloud services through OCI, including computing, storage, and networking services, as well as infrastructure technology.

According to Wikipedia, Oracle Cloud was available in 44 regions as of July 2023, each with at least one availability domain and three fault domains per availability domain; Oracle’s region map gives the current count. All over the United States, Europe, Canada, the Middle East, Africa (EMEA), Latin America, and Asia Pacific are these regions and availability zones. For the US government, the US Department of Defense (DoD), and the UK government, Oracle Cloud also provides federal cloud regions.

Tencent Cloud

Tencent Cloud, a division of Tencent Holdings, is headquartered in Shenzhen, China, and is not a US company. According to Canalys data cited by Wikipedia, Tencent Cloud was the third-largest cloud provider in China, with a 15% share, in the third quarter of 2024.

According to Wikipedia, Tencent Cloud operates 66 availability zones across 23 regions globally, supported by more than 3,200 content delivery nodes. Older counts that mixed in partner regions gave different totals, so Tencent Cloud’s own region list is the best check for the current figure. Tencent Cloud operates in Mainland China, the US, Brazil, Germany, and Asia Pacific, excluding its partner territories.

DigitalOcean

Developers, start-ups, and small- and medium-sized enterprises (SMBs) are among the smaller clients that DigitalOcean serves with on-demand infrastructure and platform tools.

As of September 2026, DigitalOcean’s documentation lists 16 datacenters across 13 regions, plus three Paperspace datacenters. DigitalOcean is listed on the New York Stock Exchange (NYSE: DOCN), Wikipedia lists its headquarters as Broomfield, Colorado, and the company reported Q2 2026 revenue of US$281 million, up 29% year over year, from more than 680,000 customers. Its datacenters are in New York City, San Francisco, Atlanta, Richmond, Kansas City and Memphis in the United States, plus Toronto (Canada), London (UK), Amsterdam (Netherlands), Frankfurt (Germany), Bangalore (India), Singapore and Sydney (Australia).

These 10 organizations cover most business needs for cloud computing solutions. Everyone can find something here, ranging from robust Infrastructure as a Service (IaaS) platforms like Amazon Web Services (AWS) and Microsoft Azure to Software as a Service (SaaS) suites like Salesforce! However, it’s crucial to conduct a thorough study before making a decision so you can decide what would work best for your company’s requirements.

Which Cloud Computing Companies Are Headquartered in the USA?

Eight of the ten cloud computing companies in this list are headquartered in the United States. Alibaba Cloud and Tencent Cloud are Chinese providers that compete with US companies in Asia and are included only for comparison. The table below shows where each company is based and one recent, dated figure for scale.

Company-wide revenue (for example Oracle or Broadcom) includes far more than cloud services, so the figures show the size of each business, not a like-for-like cloud ranking.

Who Leads the Cloud Infrastructure Market?

Amazon Web Services leads the worldwide cloud infrastructure market. According to Synergy Research Group’s report of November 19, 2025, enterprise spending on cloud infrastructure services (IaaS, PaaS and hosted private cloud) reached US$106.9 billion in the third quarter of 2025.

• Amazon (AWS): 29% market share
• Microsoft (Azure): 20% market share
• Google (Google Cloud): 13% market share
• The big three together: 63% of spending

Synergy Research Group also reported that Oracle was gradually gaining share, and that the rest of the market is split between Alibaba, Salesforce, IBM, fast-growing “neoclouds” such as CoreWeave, Crusoe, Nebius and Lambda, and a long tail of small providers. Synergy separately estimated the total cloud market at US$330 billion for 2024, with generative AI driving about half of that year’s growth.

What Is Cloud Computing? IaaS, PaaS and SaaS Explained

Cloud computing is a model for on-demand network access to a shared pool of configurable computing resources, according to the US National Institute of Standards and Technology (NIST Special Publication 800-145, September 2011). NIST lists five essential characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity and measured service.

NIST defines three service models, and the companies in this list sit in different ones:

• Infrastructure as a Service (IaaS): rented computing, storage and networking. AWS, Microsoft Azure, Google Cloud, Oracle Cloud Infrastructure, IBM Cloud and DigitalOcean all sell IaaS.
• Platform as a Service (PaaS): managed platforms for building and running applications, such as databases and developer tools, offered by the same large providers.
• Software as a Service (SaaS): finished applications delivered over the internet. Salesforce is the main SaaS company in this list, selling customer relationship management (CRM) software by subscription.

VMware is different again: it mainly sells software that companies use to build their own private and hybrid clouds. For more US software-as-a-service firms, see this list of top SaaS companies in the USA.

What Has Changed Since This List Was First Published?

• Broadcom bought VMware. The US$69 billion deal closed on November 22, 2023. VMware stopped selling perpetual licenses for products such as vSphere and Cloud Foundation and moved to subscriptions only, and its End-User Computing division was sold to KKR and renamed Omnissa.
• Kyndryl is fully separate from IBM. Kyndryl began trading on the New York Stock Exchange (NYSE: KD) on November 4, 2021, and reported about US$15.1 billion in revenue for 2025.
• Oracle changed headquarters. Oracle moved from Redwood Shores, California, to Austin, Texas, in December 2020, and in April 2024 announced a plan to move to Nashville, Tennessee, without giving a timeframe.
• The largest providers added regions. AWS went from 26 to 39 regions and Google Cloud from 34 to 43, based on the figures in the original article and each company’s current locations page.
• DigitalOcean expanded in the US. Its current datacenter list includes Atlanta, Richmond, Kansas City and Memphis, which were not in the original list, and its investor page now presents it as an AI-focused cloud infrastructure company.

How to Choose a Cloud Computing Provider

The right cloud provider depends on what the business needs to run, where its data must live and which skills its team already has. These steps help narrow the choice:

1. Decide the service model. Pick IaaS or PaaS (AWS, Azure, Google Cloud, Oracle, IBM, DigitalOcean) for running your own applications, or SaaS (such as Salesforce) for ready-made software.
2. Check regions near your users. Compare each provider’s region list against the countries where your customers are and where data-residency rules apply.
3. Check compliance. US government workloads need providers with the right authorizations; Oracle, for example, runs a US government cloud with FedRAMP High and DISA SRG IL5 compliance.
4. Price a real workload. Estimate the cost of the same workload with each provider, including data-transfer charges, instead of comparing headline list prices.
5. Plan security and exit. Read the shared-responsibility terms, review the common causes of data breaches in the cloud, and keep a plan for moving data out if prices or terms change.
6. Match team skills. Teams can build skills through the AWS Cloud Practitioner certification or Microsoft Azure certifications; teams moving to Google can follow a Google Cloud migration plan.

Smaller firms with simpler needs can start with a developer-focused provider such as DigitalOcean; this guide explains why small businesses choose cloud computing and storage.
