Cloud computing platforms are online services that provide computing resources over the internet. They allow users to store data, run applications, and access software without needing physical hardware. This flexibility enables businesses and individuals to scale their operations easily and pay only for what they use. These platforms typically offer various services, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Popular examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. By using these services, users can enhance collaboration, improve efficiency, and reduce costs.
