3.1.10 Cloud computing model

Cloud computing is different from the client−server model in that servers and services are dispersed all over the globe in distributed data centres. With cloud computing, there is a significant shift in workload. Cloud computing allows end users to access applications from servers located in the cloud instead of requiring an end device client.

In Cloud computing, data is synchronised across multiple servers, so that servers in one data centre maintain the same information as servers in another location. Organisations simply subscribe to different services within the cloud. Individual organisations are no longer responsible for maintaining the application updates, security, and backups. This becomes the responsibility of the organisation offering the cloud service.

Microsoft Outlook is a client−server system that is typically set up for a specific organisation. End users connect to the email server using a locally installed email client. Gmail is a cloud computing program that allows users from anywhere to log into their Gmail account. A user is able to create, access, and modify emails from virtually anywhere that they have an Internet connection, over a variety of devices and operating systems. Users no longer must keep email clients up-to-date or install new features; these application updates are performed automatically on the server.
