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).

Cloud Summary outline

• Cloud computing is an umbrella term used to refer
  to Internet based development and services
• Introduction to cloud context
• Technology context multi-core, virtualization,
  64-bit processors, parallel computing models,
  big-data storages
• Cloud models IaaS (Amazon AWS), PaaS (Microsoft
  Azure), SaaS (Google App Engine)
• A number of characteristics define cloud data,
  applications services and infrastructure
• Remotely hosted Services or data are hosted on
  remote infrastructure.
• Ubiquitous Services or data are available from
  anywhere.
• 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!

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

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.

Benefits of Cloud Computing

• On-demand self-service
• Broad network access
• Rapid elasticity
• Measured service
• Lower costs
• Reliability

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.

Answer The Cloud Computing?

• Typical requirements and models
• platform (PaaS),
• software (SaaS),
• infrastructure (IaaS),
• 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.

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.

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.

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 enterpris
  e 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 clientserver model).
