Cloud comping is one of the booming topic in it department. My presentation will discuss the major points of the cloud computing .So hope you find what you where looking for
3. History
1950s
In the 50s mainframe computers were huge, occupying
entire rooms. Due to the cost of buying and maintaining
mainframes, organizations couldn’t afford to purchase
one for each user. The solution was “time sharing” in
which multiple users shared access to data and CPU
time. The term “time sharing” is the premise of cloud
computing.
1969s
J.C.R. Licklider developed the ARPANET (Advanced
Research Projects Agency Network) – the network that
became the basis of the internet. His vision was for
everyone on the globe to be interconnected and
accessing programs and data at any site, from anywhere.

1970s
IBM released an operating system called VM that
allowed admins to have multiple virtual systems, or
“Virtual Machines” (VMs) on a single physical node. The
VM operating system took the 50s “time sharing” model
to the next level and most of the basic functions of any
virtualization software that you see nowadays can be
traced back to this early VM operating system.
1990s
Telecommunications companies started offering virtualized private
network connections, which meant it was possible to allow for
more users through shared access to the same physical
infrastructure. This change enabled traffic to be shifted as necessary
to allow for better network balance and more control over
bandwidth usage. Meanwhile, virtualization for PC-based systems
started in earnest, and as the Internet became more accessible, the
next logical step was to take virtualization online.

1997
The term “cloud computing” is created by University of
Texas professor Ramnath Chellappa in a talk on a “new
computing model.”
However, the term may actually have been used a year
earlier in Compaq.
2002
Amazon created Amazon Web Services (AWS),
providing an advanced system of cloud services
from storage to computation.
2009
Google and Microsoft entered the playing field.
The Google App Engine brought low-cost
computing and storage services, and Microsoft
followed suit with Windows Azure.
6. Introduction
What is cloud computing?
Cloud Computing is a general term used to describe a new class of network based
computing that takes place over the Internet,
a collection/group of integrated and networked hardware, software and Internet
infrastructure (called a platform).
Using the Internet for communication and transport provides hardware, software
and networking services to clients
These platforms hide the complexity and details of the underlying infrastructure from
users and applications by providing very simple graphical interface or API
(Applications Programming Interface).
7. Continue……
In addition, the platform provides on demand services, that are always on, anywhere,
anytime and any place.
Pay for use and as needed, elastic
The hardware and software services are available to
general public, creativities, corporations and businesses markets
Wikipedia’s Definitions
Cloud computing is a computing model shift where computing is moved away
from personal computers or an individual server to a “cloud” of computers.
Cloud computing is Internet-based ("cloud") development and use of computer
Technology ("computing"). The cloud is a representation for the Internet, based on how
it is shown in computer network diagrams, and is an concept for the complex
infrastructure it covers.
8. service models Based
Infrastructure-as-a-Service (IaaS)
A service model that involves outsourcing the basic infrastructure used to support operations--including
storage, hardware, servers, and networking components.
The service provider owns the infrastructure equipment and is responsible for housing, running, and
maintaining it. The customer typically pays on a per-use basis.
The customer uses their own platform (Windows, Unix), and applications
Platform-as-a-Service (PaaS)
A service model that involves outsourcing the basic infrastructure and platform (Windows, Unix)
PaaS facilitates deploying applications without the cost and complexity of buying and managing the underlying
hardware and software where the applications are hosted.
The customer uses their own applications
9. Software-as-a-Service (SaaS)
Also referred to as “software on demand,” this service model involves outsourcing the infrastructure, platform,
and software/applications.
Typically, these services are available to the customer for a fee, pay-as-you-go, or a no charge model.
The customer accesses the applications over the internet.
10. Deployment Model Based
Depends upon how a cloud is setup/deployed:
Private: Operated by and for an individual entity.
Public: Available to general public connected together.
Hybrid: Private and Public connected together.
Community: Setup by and for a group having shared goals.
12. Cloud-Sourcing
Why is it becoming a Big Deal:
Using high-scale/low-cost providers,
Any time/place access via web browser,
Rapid scalability; incremental cost and load sharing,
Can forget need to focus on local IT.
14.
Drawbacks
Does not work well with low-speed connections:
Features might be limited:
Stored data might not be secure:
Stored data can be lost:
No longer in control
15. Conclusion
Cloud computing will promote the use of shared resources and when we are sharing the
resources among different users it will definitely lower the costs and will help in keeping the
environment clean.
Cloud computing will also help in e-learning by providing many services online for the
students.
We need to strap up this technology in our daily lives by creating many applications on
cloud.
