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

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
  • 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
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.
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

On-demand Self-Service
Clients can provision computer resources without
the need for interaction with cloud service
provider personnel.
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
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.
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.
Lower Costs
Because cloud networks operate at higher
efficiencies and with greater utilization,
significant cost reductions are often
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
  • 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.

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

  • 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

  • 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.

Service Model Types
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
  • 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).

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

Insane Technologies Promise

  • We illustrated cloud concepts and demonstrated
    the cloud capabilities through simple
  • We discussed the features of the Hadoop File
    System, and mapreduce to handle big-data sets.
  • We also explored some real business issues in
    adoption of cloud.
  • Cloud is indeed an impactful technology that is
    sure to transform computing in business.
