Cloud hosting refers to the delivery of hosting services over the internet, using a network of remote servers. These servers are typically owned and maintained by a cloud hosting provider, and customers can access the resources they need, such as storage, computing power, and software, on a pay-as-you-go basis. This allows for greater flexibility and scalability than traditional, on-premises hosting, as customers can easily add or remove resources as their needs change. Additionally, because the servers are maintained by the provider, customers do not have to worry about hardware and software maintenance and upgrades.
