Top 10 Cloud Computing Companies in USA
SUMMARY
Cloud computing has become an important part of modern business. Companies use cloud platforms to store information, run applications, manage databases, build software, analyze data, and deploy artificial intelligence tools. Instead of maintaining all their computing infrastructure themselves, businesses can access resources through cloud providers and scale them according to their needs.
The United States is home to several of the world’s largest cloud computing companies. Amazon Web Services (AWS), Microsoft Azure, and Google Cloud dominate the global infrastructure market, while companies such as Oracle, IBM, Salesforce, DigitalOcean, and Rackspace serve different segments of
the market. AWS, Azure, and Google Cloud together accounted for more than 60% of global cloud infrastructure spending in late 2025.
