The document outlines the fundamental concepts and benefits of cloud computing, detailing its history, types (public, private, hybrid), and service layers (SaaS, PaaS, IaaS). It emphasizes the significance of cloud computing for organizations like NASA, highlighting how it can enhance their computational capabilities and data management. The text also discusses various applications and future potential within educational contexts.

4. CLOUD COMPUTING
According to Wikipedia :
“Cloud computing is Internet-based
computing, whereby shared resource,
software, and information are provided to
computers and other devices on demand, like
the electricity grid”
It puts customers information and or
applications in a virtual “cloud” that can be
accessed through the web.

5. Evolution from Grid to Cloud Computing

6. Traditional Software Vs Cloud computing

8. • Public Cloud : The services are delivered to
the client via the Internet from a third party
service provider.
Example : Amazon

9. • Private Cloud : These services are managed and
provided within the organization. There are less
restriction on network bandwidth, fewer security
exposures and other legal requirements compared
to the public Cloud.
Example : HP Data Centers

10. Hybrid Cloud : It is a combination of services provided
by the Private and public cloud.
Example:
•ERP in private cloud
•Sales & Email in public

11. Cloud computing is :
User centric
 Accessible
 Intelligent
 Programmable

FEATURES
Reliability
Scalability
Security

13. Cloud Service Layers -
Characteristics
• Sometimes free; easy to use; good consumer
adoption; proven business models
• You can only use the application as far as what it
is designed for
Software as a
Service (SaaS)
• Developers can upload a configured applications
and it “runs” within the platform’s framework;
• Restricted to the platform’s ability only;
sometimes dependant on Cloud Infrastructure
provider
Platform as a
Service (PaaS)
• Offers full control of a company’s infrastructure;
not confined to applications or restrictive
instances
• Sometimes comes with a price premium; can be
complex to build, manage and maintain
Infrastructure
as a Service
(IaaS)

14. Cloud Service Layers -
