Curious to know what is cloud computing? Go through our presentation to know the basics of cloud computing...

1. Introduction to Cloud Computing

2. Introduction
• "Cloud Computing", by definition, refers to the on-demand
delivery of IT resources and applications via the Internet
with pay-as-you-go pricing.
• With cloud computing, you don’t need to make large upfront
investments in hardware and spend a lot of time on the
heavy lifting of managing that hardware
• You can provision exactly the right type and size of
computing resources you need to power your newest bright
idea or operate your IT department.
• Pay as you need

3. Example
Yahoo, Gmail, Hotmail :-
Instead of running an e-mail program on your
computer, you log in to a Web e-mail account
remotely. The software and storage for your account
doesn't exist on your computer -- it's on the service's
computer cloud.

4. History
• Concept evolved in 1950(IBM) called RJE (Remote Job
Entry Process).
• In 2006 Amazon provided First public cloud AWS(Amazon
Web Service).

5. How Does it Work?
• Cloud Computing provides a simple way to access servers,
storage, databases and a broad set of application services
over the Internet.
• Cloud Computing providers such as Amazon Web Services
own and maintain the network-connected hardware required
for these application services, while you provision and use
what you need via a web application.

6. Advantages
• Reduce the complexity of networks.
• Do not have to buy software licenses.
• Customization.
• Cloud providers that have specialized in a
particular area (such as e-mail) can bring
advanced services that a single company
might not be able to afford or develop.
• scalability, reliability, and efficiency.
• Info. at cloud are not easily lost.

9. Service Models
• SaaS – Software as a Service
• IaaS – Infrastructure as a Service
• PaaS – Platform as a Service
• DaaS – Desktop as a Service

10. Middleware: Like Apache Server
Runtime: Like Language Runtime
Data: Could be Database

11. What is ARPANET?

12. Service Models

13. Saas
• SaaS is a software delivery
methodology that provides licensed
multi-tenant access to software and
its functions remotely as a Web-
based service.
– Usually billed based on usage
– Usually multi tenant environment
– Highly scalable architecture

14. SaaS Examples

15. IaaS
• IaaS is the delivery of technology
infrastructure as an on demand
scalable service
– Usually billed based on usage
– Usually multi tenant virtualized
environment
– Can be coupled with Managed
Services for OS and application
support

16. IaaS Example

17. PaaS
• 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.
– Typically applications must be
developed with a particular platform
in mind
– Multi tenant environments
– Highly scalable multi tier architecture

18. PaaS Example

19. Deployment Models
• Public cloud
• Private cloud
• Hybrid cloud
• Community cloud
