Mohammed Hammoud: Cloud Computing

Cloud computing is a shared space on the Internet that provides processing data and resources and share them between computers and other devices. In other words, any data or programs that is stored in the cloud can be accessed through the Internet.

The word "cloud" is usually used in science to describe a large mass of object that appears as a cloud from a distance. There's also another meaning, in the old programs, to draw a network diagram that surrounded the icons for the server they used circles. So a group of servers looked like cloud.

There are many applications of cloud, Office Online by Microsoft. Office Online offers a number of web apps online, for example, Word, Excel, PowerPoint, etc. Also, Google Drive is one of the common cloud examples. It has a lot of storage found online so it works with the cloud apps that are available: Google Docs, Google Sheets, and Google Slides. It's also available for different devices so it can be accessed on a desktop or a tablet or a smartphone. All your data that are in Gmail, Google Calendar, Google Maps, Youtube, and more can also be accessed through your Google account, which makes life easier. Apple iCloud can be considered as a cloud service as well. It's mainly used for backup and synchronization of the data that is stored in the devices connected with the cloud. Data can be mail, contacts, calendar and so on. It also contains a special feature which is "Find my iPhone" and this feature is used to find an iPhone(or any Apple products) when it goes missing.

There are many service models of cloud computing, Software as a Service (Also known as SaaS) is one of them. 'SaaS, or in other words, "cloud-based applications" run on distant computers "in the cloud" and operated by others that connect via Internet and, usually, a web browser.' (IBM) SaaS is beneficial because it can be accessed from any connected computer. Moreover, it reduces data loses if a computer breaks or any app crashes. Also, it's easy to start using innovative business apps by signing up. Another service model is Public cloud. They're owned and operated by companies and it offers access over a public network. Unlike other service models, public clouds doesn't need a specific hardware nor software since it's managed by the company that owns the cloud.

Quesions:

1. What is a service model?
2. How does it work?
3. How does cloud hardware (like Chromebook) work and how does it connect with the cloud that is available in the Internet?
