3. Cloud Computing
Cloud Computing is the various services which
are provided by computer using through the
internet. Such as Software Development
platforms , Servers , Storage and networking etc.

4. Other
Definitions
“Digital transformation is helping companies rapidly
drive efficiency, agility, and connectivity as they use
technology to transform their business processes into
something easier, faster, and more secure, flexible
and profitable. Cloud computing technology is a
cornerstone to digital transformation.”
_CISCO
“Cloud computing is the delivery of computing
services—including servers, storage, databases,
networking, software, analytics, and intelligence—over
the Internet (“the cloud”) to offer faster innovation,
flexible resources, and economies of scale.”
_Microsoft

5. History of
Cloud Computing
• 1950:Time Sharing – The premise of cloud
computing
• 1969:ARPANET(Advanced Research Projects
Agency Network) – Developed by J.C.R. Licklider.
• 1970s: IMB Released an OS called VM. It enables
to have multiple virtual systems on a single physical
node.
• 1990s: Telecommunication Companies offered
virtualized private network connections
• 1997: Professor Ramnath Chellappa (University of
Texas) is coined the term of “Cloud Computing” in a
lecture on “new computing paradigm”
• 2002: AWS Provided advanced system of cloud
services from storage to Computation.
• 2006: AWS introduce the Elastic Compute Cloud as
a commercial web service
• 2009: Google and Microsoft entered to the with low
cost computing and storage services

7. Why
Cloud Computing ?
• High Speed
• Lower Cost for users (Infrastructure ,
maintenance)
• Flexibility
• Competitive Advantage for business
• Sporadic batch processing
• Back-up and restore data

8. Why Not
Cloud Computing ? • Risk of Vulnerability attacks
• Depend on Network connectivity
• Limited Control

11. Cloud Deployment Models
10

12. Public Clouds
• “Computing services offered by third-party
providers over the public Internet, making
them available to anyone who wants to use or
purchase them.”
~ Azure
• Benefits of Public Clouds
• Enables Scalability
• Only Paying for the usage
• Save Time
• High Reliability
• Constraints of Public Clouds
• Loss of Control
• Lack of Customization
• Low Performance
11

13. Private Clouds
• Computing services offered either over the
Internet or a private internal network and only
to select users instead of the general public..
~ Azure
• This will deliver under two service models.
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
• Benefits
• Have proper control for the user
• Security is high
• Ease of customization
• Compliance
• Constraints of Public Clouds
• High Cost
• Complexity is high
12

14. Hybrid
Hybrid Clouds
• “Computing environment that combines a public
cloud and a private cloud by allowing data and
applications to be shared between them. ”
~ Tutorialspoint.in
• Public cloud is using for Non-Critical Activities
and Private cloud is using for Critical Activities.
• Benefits
• Cost Saving
• Scalability is high
• High Security
• Flexible
• Constraints of Hybrid Clouds
• Reliability is low
• Hard to centralize
Private Public
13

15. Community Cloud
• Cloud computing solution to a limited number
of individuals or organizations that is
governed, managed and secured commonly
by all the participating organizations or a third-
party managed service provider.
• Benefits of Community Cloud
• Improved Service
• Scalability is high
• Availability
• Flexible
• Constraints of Community Clouds
• High Cost

16. CloudService Models
(X as a Service)
15

17. Infrastructure as a
Service
• IaaS is centered around a model of service
delivery that provisions a predefined,
standardized infrastructure specifically
optimized for the customer’s applications
• Customers maintain ownership and
management of their application(s) while the
transition, hosting operations and
infrastructure management to the IaaS
provider
• Examples
• DigitalOcean
• Linode
• Rackspace
• Amazon Web Services (AWS)
• Cisco Metapod 16

18. Infrastructure as a
Service
• Benefits
• Use of the latest technology for
infrastructure equipment.
• Reduced risk by having off-site
resources
• Reduced time, cost, and complexity in
adding new features or capabilities.
• Constrains
• Internet connection is a must.
• Depends on virtualization services.
• This service restricts user-privacy &
customization.
Benefits and Constrains
17

19. Platform as a
Service
• PaaS developers are concerned only with
web-based development and generally do not
care what operating system is used
• Facilitate to Workflow facilities for application
design
• Application development, testing, deployment,
and hosting
• Integration with web services and databases
• Support for Simple Object Access Protocol
(SOAP)
• Other interfaces allows PaaS offerings to
create combinations of web services
• Examples:
• AWS Elastic Beanstalk
• Windows Azure
• Google App Engine
• OpenShift 18

20. Platform as a
Service
• Benefits
• Scalability
• Simple and easy to use
• Low cost
• Reduced time, cost, and complexity in
adding new features or capabilities.
• Constrains
• Vendor migrations
• Mix-up local and connecting with other
clouds increase complexity
Benefits and Constrains
19

21. Software as a
Service
• 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
• Varieties of SaaS
• Vertical SaaS and Horizontal SaaS
• Software can use with SaaS model
• Accounting
• Customer relationship management
• Email software
• Human resources
• IT security
• IT service management
• Video conferencing
20

22. Software as a
Service
• Benefits
• Scalability
• Simple and easy to use
• Flexible
• Up to Date
• Constrains
• Connectivity is a must
• Performance
• Security
• Limited Vary of application
Benefits and Constrains
