Cloud hosting is a type of web hosting that uses multiple different servers to balance the load and maximize uptime.
Other types of hosting are shared hosting and VPS. Shared hosting is a computer connected to the internet, with a hard drive and other resources shared with other websites. VPS (virtual private servers) are single virtual servers that host one website. A computer can host several VPS.
Instead of a single server, a website in cloud hosting can access a “cluster” (a set of servers) that uses resources from a centralized pool. Even if one server fails, another is activated to keep everything running.
