The document discusses cloud computing, including definitions, history, virtualization, hardware, services, architecture, and advantages/disadvantages. It defines cloud computing as IT capabilities provided over the internet, including on-demand scaling. The history discusses early concepts in the 1960s and key contributions from Amazon (EC2 in 2006) and Google Docs. Virtualization allows efficient utilization of hardware and separation of software. Common cloud services are SaaS, PaaS, and IaaS. Architecture includes public, private and hybrid cloud models. Advantages include cost savings and flexibility, while disadvantages relate to security, control and vendor lock-in.

What is cloud computing ?
“Cloud computing is a style of computing where massively
scalable IT-related capabilities are provided as a service
across the Internet to multiple external customers”
“Cloud computing: A pool of abstracted, highly scalable, and
managed infrastructure capable of hosting end-customer
applications and billed by consumption”
“Cloud computing is Web-based processing, whereby shared
resources, software, and information are provided to computers and
other devices (such as smart phones) on demand over the Internet.”

History
when John McCarthy wrote that “computation may someday be
organized as a public utility.” Then, grid computing, a concept that
originated in the early 1990s as an idea for making computer power as
easy to access as an electric power grid also contributed to cloud
computing.
The general idea behind the technology dates back to the 1960s,

History
One of the first movers in cloud computing was Salesforce.com,
which in 1999 introduced the concept of delivering enterprise
applications via a simple website.
In 2002 Amazon started Amazon Web Services, providing
services like storage, computation and even human intelligence.
The year 2006 also saw the introduction of Amazon’s Elastic Compute cloud (EC2) as a commercial
web service that allowed small companies and individuals to rent computers on which to run their
own computer applications.

Microsoft Office 2013 (also called Office 2013 and
Office 15) is the upcoming version of the Microsoft
Office productivity suite
Office 2013 is more "cloud-based" than previous
versions.
This is notable as the default save location is the
user's SkyDrive.

Virtualization
Virtualization is “something which is not REAL, but displays the full qualities of
the REAL”.
Virtualization :
• hardware platform,
• operating system,
• storage device,
• network resources,
• Software implementation.

HistoryWhat is cloud computing ? VirtualizationVirtualization Cloud Computing hardware Cloud Computing services Cloud Architecture Advantages & Disadvantages
In hardware virtualization, the host machine is the actual machine on which
the virtualization takes place, and the guest machine is the virtual machine.
The words host and guest are used to distinguish the software that runs on
the actual machine from the software that runs on the virtual machine. The
software or firmware that creates a virtual machine on the host hardware is
called a hypervisor or Virtual Machine Manager.
