INTRODUCTION
Cloud computingis Internet-based computing, whereby shared
resources, software, and information are provided to computers
and other devices on demand, like the electricity grid.
Cloud computing is a paradigm shift following the shift from
mainframe to client–server in the early 1980s. Details are
abstracted from the users, who no longer have need for
expertise in, or control over, the technology infrastructure "in
the cloud" that supports them.

WHAT IS CLOUDCOMPUTING?
Cloud computing is Internet based computing where
virtual shared servers provide software,
infrastructure, platform, devices and other resources
and hosting to customers on a pay-as-you-use basis.
All information that a digitized system has to offer is
provided as a service in the cloud computing model.
Users can access these services available on the
"Internet cloud" without having any previous know-
how on managing the resources involved.

HISTORY
Concept originatedfrom telecommunication companies
changing to VPN
1999:Salesforce. com Delivery of applications via web
‐
2002: Amazon launches Amazon Web Services (AWS)
2006: Google Docs, Amazon Elastic Compute Cloud
(EC2)
2008: Eucalyptus
2009: Microsoft Azure

ARCHITECTURE
Cloud architecture,the systems architecture of
the software systems involved in the delivery of
cloud computing, typically involves multiple
cloud components communicating with each
other over application programming interfaces,
usually web services.
7.
CLOUD COMPUTING SAMPLE
ARCHITECTURE
This resembles the UNIX philosophy of having
multiple programs each doing one thing well and
working together over universal interfaces. Complexity
is controlled and the resulting systems are more
manageable than their monolithic counterparts.
The two most significant components of cloud
computing architecture are known as the front end
and the back end.
The front end is the part seen by the client, i.e. the
computer user. This includes the client’s network (or
computer) and the applications used to access the
cloud via a user interface such as a web browser.
The back end of the cloud computing architecture is
the ‘cloud’ itself, comprising various computers,
servers and data storage devices.
PUBLIC CLOUD
Publicclouds are made available to the general public
by a service provider who hosts the cloud
infrastructure. Generally, public cloud providers like
Amazon AWS, Microsoft and Google own and operate
the infrastructure and offer access over the Internet.
With this model, customers have no visibility or
control over where the infrastructure is located. It is
important to note that all customers on public clouds
share the same infrastructure pool with limited
configuration, security protections and availability
variances.
10.
PRIVATE CLOUD
Privatecloud is cloud infrastructure dedicated to a
particular organization. Private clouds allow
businesses to host applications in the cloud, while
addressing concerns regarding data security and
control, which is often lacking in a public cloud
environment.
It is not shared with other organizations, whether
managed internally or by a third-party, and it can be
hosted internally or externally.
11.
HYBRID CLOUD
HybridClouds are a composition of two or more clouds
(private, community or public) that remain unique
entities but are bound together offering the
advantages of multiple deployment models.
In a hybrid cloud, you can leverage third party cloud
providers in either a full or partial manner; increasing
the flexibility of computing. Augmenting a traditional
private cloud with the resources of a public cloud can
be used to manage any unexpected surges in
workload.
12.
COMPONENTS
SaaS (softwareas a service): SaaS refers to software
that’s made available as a web-based service.
Utility computing: The predecessor of cloud computing,
utility computing provides the ability to access storage and
virtual servers on demand.
Cloud-based web services: Similar to Saas, web services
in the cloud allow you to offer services online, such as
credit card processing services, employee payroll
processing or viewing an interactive map.
MSP (managed service providers): The grandfather of
cloud computing, an MSP delivers applications to IT
instead of end-users.
IaaS (infrastructure as a service): IaaS refers to
computer infrastructure (e.g., virtualization) that’s
delivered as a service.
13.
RECENT DEVELOPMENT’S
In2007, Google, IBM, and a number of universities
embarked on a large scale cloud computing research
project. In early 2008, Eucalyptus became the first
open source AWS API compatible platform for
deploying private clouds.
14.
ADVANTAGES OF CLOUD
COMPUTING
Flexibility: There is a high rate of flexibility.
Low Cost: Companies can save big by employing
cloud computing as it eliminates cost for hardware and
software.
Speed & Scales :Traditional methods to buy and
configure hardware and software are time consuming.
Easier Management of Data and Information:
Since all data are located on a centralized location,
data are more organized making it easy to manage.
Device Diversity :We can access our applications
and data anywhere in the world, on any system.
15.
ADVANTAGES OF CLOUD
COMPUTING…
Increased Storage Capacity :Increased Storage
Capacity is another benefit of the cloud computing, as
it can store more data as compared to a personal
computer.
Easy to Learn and Understand: Since people are
quiet used to cloud applications like Gmail, Google
Docs, so anything related to the same is most likely to
be understood by the users.
Automatic Updating: It saves companies time and
effort to update multiples server.
Customize Setting: Cloud computing also allows you
to customize your business applications.
16.
DISADVANTAGES OF CLOUD
COMPUTING
Dependency: One major disadvantages of cloud
computing is user’s dependency on the provider.
Risk: Cloud computing services means taking
services from remote servers.
Requires a Constant internet connection:
The most obvious disadvantage is that Cloud
computing completely relies on network
connections.
Security: Security and privacy are the biggest
concerns about cloud computing.
Migration Issue: Migration problem is also a
big concern about cloud computing.
17.
CONCLUSION
So, whilecloud computing is really really great
and you’re probably already using it, either for
business of for personal means, here’s what we’ve
learned from taking a look at the pros and cons:
Cloud computing is a really cheap way for
companies to have all the resources they need in
once place.
It’s a much better way to spread your resources,
and it becomes easier to access things from
longer distances.
