4. Beyond the Desktop: An Introduction to Cloud Computing
Cloud computing is a concept where applications and
files are hosted on a “cloud” consisting of thousands of computers and servers, all linked together and accessible via the Internet.
With cloud computing, everything you do is now web based instead of being desktop based. You can access all your programs and documents from any computer that’s connected to the Internet.

7. Understanding Cloud Architecture
Users select a task or service (either starting an application or opening a document).
User’s request goes to the system management, which finds the
correct resources and then calls the system’s appropriate provisioning services.
These services
> Carve out the necessary resources in the cloud
> Launch the appropriate web application
> Opens the requested document.
Web application is launched
System’s monitoring functions track the usage of the cloud so that resources are apportioned and attributed to the proper user(s).
User is charged according to the amount of utilities and resources used.

9. Understanding Cloud Storage
With cloud storage, data is stored on multiple third-party servers, rather than on the dedicated servers.
When storing data, the user sees a virtual server—that is, it appears as if the data is stored in a particular place with a specific name.
In reality, the user’s data could be stored on any one or more of the computers used to create the cloud.
Data stored in the cloud is secure from accidental erasure or hardware crashes, because it is duplicated across multiple physical machines.

10. 3 Cloud Service Models Cloud Software as a Service (SaaS)
Use provider’s applications over a network
Cloud Platform as a Service (PaaS)
Deploy customer-created applications to a cloud
Cloud Infrastructure as a Service (IaaS)
Rent processing, storage, network capacity, and other fundamental computing resources
To be considered “cloud” they must be deployed on top of cloud infrastructure that has the key characteristics

14. Finally …
In short, cloud computing enables a shift from the computer to the user, from applications to tasks, and from isolated data to data that can be accessed from anywhere and shared with anyone.
The user no longer needs to remember where the data is. All that matters is that the data is in the cloud, and thus immediately available to that user
and to other authorized users.
