Cloud computing companies provide services that allow individuals and businesses to store, manage, and process data over the internet instead of on local servers or personal computers. These companies offer various solutions, including data storage, software applications, and computing power, all accessible through the internet. Some well-known cloud computing companies include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. They enable users to scale their resources easily, reduce costs, and enhance collaboration by providing tools that can be accessed from anywhere with an internet connection.
