Public cloud providers are companies that offer computing resources and services over the internet to anyone who wants to use them. These services include storage, processing power, and applications, which can be accessed on-demand. Popular public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. Users of public cloud services typically pay only for what they use, making it a cost-effective solution for businesses and individuals. Public clouds are maintained by the providers, ensuring that users benefit from the latest technology and security measures without needing to manage the infrastructure themselves.
