This document discusses cloud computing. It defines cloud computing as utilizing remote servers and networks to allow centralized data storage and online access to computer resources. Cloud computing delivers IT services over the internet. It discusses the key attributes of cloud computing including broad network access, rapid elasticity, and pay-as-you-go pricing. It also outlines the main service models (IaaS, PaaS, SaaS), deployment models (private, public, hybrid clouds), and some security concerns regarding cloud computing such as sharing infrastructure with other tenants.

3. Importance of cloud computing
•Cloud computing has the potential to radically change the nature of Information and
Communication Technology(ICT) provision in the public service and significantly reduce costs. It
is key element of the strategic future of ICT in this sector.
•We believe we are moving out of the ICE Age, the Iron Age, The industrial Age, the Information
Age, to the participation Age. You are participating on the Internet, not just viewing stuff. We
build the infrastructure that goes in the data centre that facilitates the participation age.
-Scott McNealy, former CEO, Sun Microsystems

5. What is Cloud Computing?

6. What is Cloud computing?
•Cloud computing is a recently evolved computing terminology or metaphor based on utility and
consumption of computing resources. Cloud computing involves deploying groups of remote
servers and software networks that allow centralized data storage and online access to
computer services or resources
-Wikipedia the free encyclopaedia
•Cloud computing is a comprehensive solution that delivers IT as a service. It is an Internet-based
computing solution where shared resources are provided like electricity distributed on the
electrical grid. Computers in the cloud are configured to work together and the various
applications use the collective computing power as if they are running on a single system.
-IBM Developers

7. What is Cloud computing?
According to Forrester, Cloud Computing is:
“A form of standardized IT-based capability – such as Internet-based services,
software, or IT infrastructure- offered by a service provider that is accessible via
Internet protocols from any computer, always available and scales automatically
to adjust to demand, is either pay-per-use or advertising-based. Has Web- or
programmatic-based control interfaces, and enables full customer self-service. ”

10. Service Models

11. How cloud computing provider offer
their services?
•Infrastructure as a service(IaaS)
•Platform as a service(PaaS)
•Software as a service(SaaS)

12. Software as a Service(SaaS):
 The application is hosted centrally.
 Software testing takes place at a faster rate.
 Reduction in IT operational costs.
 No need to install new software to release
updates
Platform as a Service(PaaS):
 Facilitation of hosting capabilities.
 Designing and developing the application.
 Integrating web services and databases.
 Providing security, scalability and storage.
Infrastructure as a Service(IaaS):
 Virtualization of Desktop.
 Internet availability.
 Use of billing model.
 Computerized administrative tasks.

14. Deployment Models

15. Deployment Models
• Private cloud
• Public cloud
• Hybrid cloud
• Others
• Community cloud
• Distributed cloud
• Inter cloud
• Multi cloud

16. Public cloud
•Mega-scale Infrastructure and Services
•Sold publically
•Pay-per-use
•Multitenant application and services
•Access virtually unlimited resources

17. Private cloud
•Finite Infrastructure and Services
•Enterprise owned or leased
•Charge-back to LOBs or Users
•Cloud Computing model in a company’s own datacentre or
providers
•Access limited resources that must be managed by LOBs or
Central IT

18. Hybrid cloud
•Composition of two or more clouds
•Mixed usages of both public and private clouds
•Enables application components to be spread between multiple public and/or
private clouds
•E.g. Amazon VPC, GoGrid
