CLOUD COMPUTING
What is it?
WHAT İS CLOUD COMPUTING?
 Cloud computing is an emerging computing technology that uses
the internet and central remote servers to maintain data and
applications.
 Cloud computing provides a variety of computing resources ,
from servers and storage to enterprise applications such as
email, security, backup/DR, voice, all delivered over the
Internet.
 The Cloud delivers a hosting environment that is immediate,
flexible, scalable, secure, and available – while saving
corporations money, time and resources .
 Cloud computing providers deliver applications via the
internet, which are accessed from a Web browser, while the
business software and data are stored on servers at a remote
location.
THE AVERAGE CLOUD USER
 Connects to the cloud via the Internet
 Does computing tasks,
 Runs applications,
 Stores Data
ARCHITECTURE OF CLOUD
NIST Visual Model of Cloud Computing Definition
FIVE CHARACTERISTICS OF CLOUDS
 On-Demand Self-Service
 Broad Network Access
 Resource Pooling
 Rapid Elasticity

Measured Service
T YPE OF SERVICE
Software as a Service (SaaS)
is a software
distribution model in which applications are hosted
by a vendor or service provider and made available
to customers over a network, typically the Internet.
Ex: Google Apps, Salesforce.com
T YPES OF SERVICE
Platform as a Service (PaaS)
is a way to
rent hardware, operating systems, storage and
network capacity over the Internet. The service
delivery model allows the customer to rent
virtualized servers and associated services for
running existing applications or developing and
testing new ones.
Ex: Google App Engine,force.com
T YPES OF SERVICE
Infrastructure as a Service (IaaS)
is a
provision model in which an organization outsources
the equipment used to support operations, including
storage, hardware, servers and networking
components. The service provider owns the
equipment and is responsible for housing, running
and maintaining it. The client typically pays on a
per-use basis.
 Ex: Joyent, AmazonEC2, Amazın S3
CLOUD DEPLOYMENT MODELS
 Public Cloud: The cloud infrastructure is made available to
the general public or a large industry group and is owned
by an organization selling cloud services.
 Private Cloud: The cloud infrastructure is operated solely
for a single organization. It may be managed by the
organization or a third party, and may exist on -premises or
of f-premises.
CLOUD DEPLOYMENT MODELS
 Community Cloud: The cloud infrastructure is shared by
several organizations and supports a specific community
that has shared concerns (e.g., mission, security
requirements, policy, or compliance considerations). It may
be managed by the organizations or a third party and may
exist on-premises or of f-premises.
 Hybrid Cloud: The cloud infrastructure is a composition of
two or more clouds (private, community, or public) that
remain unique entities but are bound together by
standardized or proprietary technology that enables data
and application portability (e.g., cloud bursting for load balancing between clouds).
THE BACK STORY
From ground
to cloud
COMPUTER STORAGE
 Computers have internal or hard drive storage(C: Drive)
 CPU has a drive for storing programs, documents, pictures,
videos, presentations, etc…
Standard Computer Tower
or Central Processing Unit
(CPU)
Inside the Computer
INTERNAL STORAGE
 Content is stored on THAT computer
 To use content must return to THAT computer
 Cannot access this content from another device or computer
PROGRAMS
 Purchase programs
 Load to the computer
 Each computer would need the program loaded and stored on
the internal drive
EXTERNAL STORAGE




Allows your content to become mobile
Save to the storage device
Take device to any compatible computer
Open and use content
CD/DVD
Thumb Drive
SD Card
External Hard Drive
Micro SD Card
NETWORKED STORAGE
 Multiple work stations talk to one unit that stores information
and data.
 Data is not saved to the C: drive, but to a network drive
 Can retrieve the data stored to the network from any of the
connected workstations.
CLOUD STORAGE
Create an Account –
User name and
password
Content lives with
the account in the
cloud
Log onto any
computer with Wi-Fi
to find your content
DO YOU USE THE CLOUD?
THE CLOUD REQUIRES
 An Internet connection
 An account - Created with a user name and a password
 Agree to Terms
DOWNLOADS FOR STORAGE





Download a cloud based app to a computer you own
The app lives on your Computer
Save files to the app
When connected to the Internet it will sync with the cloud
The Cloud can be accessed from any Internet connection
UPLOAD DOCUMENTS




Log-in to the online storage account
Click upload a file
Find the file on hard drive, network, or external storage
Upload to cloud storage

 SkyDrive
 Box
DOWNLOAD REQUIRED?
INTERNET IS REQUIRED
 Creation is happening in the cloud
 Saving is going to the cloud
 To retrieve files, must return to the cloud

WHY THE CLOUD?
ADVANTAGES
 Reduced costs
• Reduction in software license and maintenance costs
by using subscription based software.
• Reduction in physical infrastructure costs by using
external servers.
 Increased flexibility
• Reduced time to develop, test, and deploy packaged
software.
• Requires upfront changes to platform but pays of f
significantly in the long run.
ADVANTAGES
 Upgradability
•Reduces time and costs to upgrade software since
there is one instance of the software.
•Minimizes down time and increases operational
ef ficiency.
 Elasticity
•Can allocate resources to specific services or process
based on fluctuating demand.
•Improves quality of IT services delivered while
minimizing unnecessary resources.
ADVANTAGES
 A gility
•Enables greater organization agility to respond to
marketplace and competitive dynamics.
•Positions the firm to attract talent that can innovate
with a variety of available solutions and tools.
 Address unmet needs
•Gives customers faster response times and increased
reliability.
•Allows customers to enter and access information from
anywhere at anytime on a variety of devices (e.g.
computer, tablet, mobile).
ADVANTAGES
 Redefining the value chain
•Organizations can shift resources from operational
items (e.g. IT) to core competencies.
•Organizations can leverage best of breed applications
and processes from other companies across the globe.
•Allow for greater ef ficiency and greater value creation.
 Business – IT Alignment
•The CIO and the IT group are no longer simply
operational in purpose, they now contribute directly to
business strategy.
•Creates unity in the C -Suite and positions the
organization to take advantage of growing importance of
IT plus upcoming IT changes.
DISADVANTAGES
 Transparency (Public): Understand if the cloud services are
operating as they should.
 Control ( Public): Ability to influence vendor-controlled IT
staf f.
 Security & privacy (Public): Data organizations do not have
direct control over their data.
 Compliance (Public): Government regulations are not always
clear or enforced (i.e. tax and legal
DISADVANTAGES
 Geographic restrictions (Public): Due to legal requirements
among dif ferent regions .
 Vendor viability (Public & Private): Ability of current cloud
vendors to sustain themselves .
 Vendor lock-in (Public): Does the Cloud vendor should use
common standards and provide services to allow portability of
cloud solution.
 Performance (Public): Bandwidth and latency still pose
issues, for high throughput workloads.
DISADVANTAGES
 IT Operations (Public & Private): Reduced operational
ef ficiency and higher costs, if the wrong application is
selected for the cloud.
 IT Readiness (Public & Private): Reduced operational
ef ficiency if the organization is not ready to change to Cloud.
