Introduction

4.
What is Cloud Computing?
Definition:
Simply, Cloud Computing is storing and accessing programs and data
over the internet instead of a computer hard drive.
The cloud is another name of the internet but nothing to do with the
hard drive.

5.
What is Cloud Computing?
“Cloud computing is a style of computing where
massively scalable IT-related capabilities are
provided as a service across the Internet to multiple
external customers”
“Cloud computing is Web-based processing,
whereby shared resources, software, and
information are provided to computers and other
devices (such as smartphones) on demand over
the Internet.”

Cloud service models

14.
Cloud Service Layers

15.
Cloud Service models - Definitions
• SaaS is a software delivery methodology that provides
licensed multi-tenant access to software and its
functions remotely as a Web-based service.
Software as a
Service (SaaS)
• PaaS provides all of the facilities required to support
the complete life cycle of building and delivering web
applications and services entirely from the Internet.
Platform as a
Service (PaaS)
• IaaS is the delivery of technology infrastructure as an
on demand scalable service.
Infrastructure as
a Service (IaaS)

16.
Cloud Service models - Containing
Software as a
Service (SaaS)
Platform as a
Service (PaaS)
Infrastructure as
a Service (IaaS)
Email Business Processes
Industry Applications CRM/ERP/HR

Cloud implementation types

19.
Cloud implementation types

20.
Public Cloud
• Owned and managed by service provider
• Made available to the general public or a large industry group

21.
Private Cloud
• Operated solely for an organization
• May be managed by the organization or a third party
• Limits access to enterprise and partner network
• Retains high degree of control, privacy and security

22.
Community Cloud
• shared infrastructure by several organizations which have
shared concerns
• May be managed by the organizations or a third party
• Costs are spread over fewer users than a public cloud but more
than a single tenant

23.
Hybrid Cloud
• Composition of two or more clouds (private, community, or
public) bound together by standardized or proprietary
technology that enables data and application portability

24.
Advantages of Cloud Computing

25.
Advantages of Cloud Computing
Lower Computing Cost
Improved Performance
Reduced Software Cost
Instant Software Updates
Unlimited Storage Capacity
Increased Data Reliability
Device Independence and the “always on!, anywhere and any
place”
 No hardware or software installation or maintenance

26.
Risks of Cloud Computing
Data privacy and security
Environmental security
Data availability and business continuity
Record retention requirements
Disaster recovery

27.
Conclusion
Cloud Computing is the fastest growing part of network based
computing . It Provides tremendous benefits to customers of all sizes:
simple users, developers, enterprises and all types of organizations.
