Cloud hosting is distribution of online resources to multiple servers.This means an unlimited number of machines are linked together to provide the same service such that when one goes offline or encounters technical difficulties,the remaining ones continue with the task.The crashing of one machine does not interrupt the performance of the task in any way.Think of it as delegating some work to many workers.When one worker gets tired,there will always be another one to continue the work.
Cloud hosting services are widely used by many websites today.Actually most of the sites we frequent use these services.Social networks such as Facebook and LinkedIn and email services such as Gmail and Hotmail are a few of the familiar websites which use cloud hosting services.They store clients' data,secure personal information and also back up information in case of loss or just deletion.
