3. What is Cloud Computing?
Cloud computing is internet-based computing in which large
groups of remote servers are networked to allow the centralized
data storage, and online access to computer services or
resources. Clouds can be classified as public, private or hybrid.
Cloud Computing is a general term used to describe a new class of
network based computing that takes place over the Internet,
Using the Interbasically a step on from Utility Computing a
collection/group of integrated and networked hardware, software and
Internet infrastructure is called a platform.
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).

4. Cloud Summary outline
Cloud computing is an umbrella term used to refer to Internet based development and services
Introduction to cloud context
o Technology context: multi-core, virtualization, 64-bit processors, parallel computing models,
big-data storages…
o Cloud models: IaaS (Amazon AWS), PaaS (Microsoft Azure), SaaS (Google App Engine)
 A number of characteristics define cloud data, applications services and infrastructure:
o Remotely hosted: Services or data are hosted on remote infrastructure.
o Ubiquitous: Services or data are available from anywhere.
o Commodified: The result is a utility computing model similar to traditional that of traditional
utilities, like gas and electricity - you pay for what you would want!

5. Cloud computing metaphor: For a user, the network
elements representing the provider-rendered services are
invisible, as if obscured by a cloud.

6. How to use a Cloud storage ? …
(ex: One Drive)
Step 1
On the Start screen, tap or
clickOneDrive to open
the OneDrive app.
Step 2
Tap or click folders to browse
to the location
on OneDrive where you
want to add the files.
Step 3
Swipe in from the top or
bottom edge of the screen
or right-click to open the
app commands, and then
tap or clickAdd files.

7. Moving and Downloading your
files….
To move files to OneDrive using File
Explorer
When you move files, you're
removing them from your PC and
adding them to OneDrive. Drag
files from the file list in the right
pane to OneDrive in the left pane.
Getting to your files from anywhere
When your files are in OneDrive,
you can get to them from any
device, even if something happens
to your PC. You can go to the
OneDrive website, or you can use
one of the mobile apps for
Android, iOS, or Windows Phone.

8. Benefits of Cloud Computing
 On-demand self-service
 Broad network
access
 Rapid elasticity
 Measured service
 Lower costs

9. On-demand Self-Service
Clients can provision
computer resources without
the need for interaction with
cloud service provider
personnel.

10. Reliability
The scale of cloud
computing networks and
their ability to provide load
balancing and failover
makes them highly reliable,
often much more reliable
that what you can achieve in
a single or organization.

11. Rapid Elasticity
The system can add resources by either scaling up
systems (more powerful computers) or scaling out
systems (more computers of the same kind), and
scaling may be automatic or manual.

12. Broad Network Access
Access to resources
in the cloud is
available over the
network using
standard methods in
a manner that
provides platform-independent
access
to clients of all types.

13. Lower Costs
Because cloud networks operate at higher
efficiencies and with greater utilization,
significant cost reductions are often
encountered.

14. Measured Service
The use of cloud system
resources is measured,
audited and reported to the
customer based on a metered
system. A client can be
charged based on a known
metric such as amount of
storage used, number of
transactions, network
input/output, amount of
processing power used and so
forth.

15. Answer: The Cloud Computing?
Typical requirements and models:
o platform (PaaS),
o software (SaaS),
o infrastructure (IaaS),
o Services-based application programming interface (API)
A cloud computing environment can provide one or more of these
requirements for a cost
Pay as you go model of business
When using a public cloud the model is similar to renting a property
than owning one.
An organization could also maintain a private cloud and/or use both.

19. Facts for Cloud Growth
1. Cut Costs on one side
2. Improved Telecom Connectivity
3. Business Process Outsourcing

20. SECURITY
Cloud computing security or, more simply, cloud
security is an evolving sub-domain of computer security,
network security, and, more broadly, information security.
It refers to a broad set of policies, technologies, and
controls deployed to protect data, applications, and the
associated infrastructure of cloud computing.
Organizations use the Cloud in a variety of different
service models (SaaS, PaaS, and IaaS) and deployment
models (Private, Public, and Hybrid). There are a number
of security issues/concerns associated with cloud
computing but these issues fall into two broad categories:
security issues faced by cloud providers (organizations
providing software-,platform-, or
infrastructure-as-a-service via the cloud) and security
issues faced by their customers

21. STORAGE
Cloud storage is a model of data storage where the digital data is
stored in logical pools, the physical storage spans multiple servers (and
often locations), and the physical environment is typically owned and
managed by a hosting company.
These cloud storage providers are responsible for keeping the data
available and accessible, and the physical environment protected
and running. People and organizations buy or lease storage capacity
from the providers to store end user, organization, or application data.
Cloud storage services may be accessed through a co-located cloud
compute service, a web service application programming interface
(API) or by applications that utilize the API, such as cloud desktop
storage, a cloud storage gateway or Web-based
content management systems.

22. Service Model Types

23. What is Open Stack?
Open Stack is a global collaboration of
developers and cloud computing
technologists producing the ubiquitous open
source cloud computing platform for public
and private clouds.
The project aims to deliver solutions for all
types of clouds by being simple to
implement, massively scalable, and feature
rich.

24. Similar Concepts
Grid computing — "A form of distributed and parallel computing,
whereby a 'super and virtual computer' is composed of a cluster of
networked, loosely coupled computers acting in concert to perform very
large tasks."
Mainframe computer — Powerful computers used mainly by large
organizations for critical applications, typically bulk data processing such
as: census, industry and consumer statistics, police and secret
intelligence services; enterprise resource planning; and financial
transaction processing.
Utility computing — The "packaging of computing resources, such as
computation and storage, as a metered service similar to a traditional
public utility, such as electricity."
Peer-to-peer — A distributed architecture without the need for central
coordination. Participants are both suppliers and consumers of resources
(in contrast to the traditional client–server model).

25. Benefits of Grid Computing
Hardware Abstraction
Ease of Migration
Encapsulation of Storage
Ease of Growth
Workload Consolidation
Improved Remote Management
Improved Monitoring and Troubleshooting
