What is Cloud Hosting?

Cloud hosting really refers to the server setup at your web host. In a traditional hosting environment, your website is hosted on a single server, often alongside multiple other websites. Your site’s performance is restricted by what that particular server is capable of, which means that under high loads (like when your newest blog post makes the front page of Digg), your site may crash.

Cloud hosts approach things differently, though. A better term might be “cluster” hosting. Servers are configured in clusters, and your site gets the benefit of multiple servers for performance. In other words, when your site suddenly gets a spike in traffic, it can utilize resources not from just a single server but from all the servers within its particular cluster.
