Cloud computing is a method of delivering computing services over the internet, including storage, networking, software, and analytics. These services are typically provided by third-party companies, such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform, and can be accessed on-demand by customers through a pay-as-you-go pricing model. This allows organizations to access technology resources without having to build and maintain them in-house, leading to cost savings and increased flexibility. Cloud computing can also enable new business models and improve agility, scalability, and disaster recovery capabilities.
