The document discusses cloud computing and its various models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It describes public clouds which allow general public access and internal/private clouds for access within an organization. Hybrid clouds that use a mix of public and private clouds are also mentioned. The document outlines some advantages of cloud computing like cost effectiveness, scalability, and reliability while also noting security and data loss concerns.

2.  Cloud is a something which is
present at remote location
 Distributed computing on internet
Or delivery of computing service
over the internet.
E.g.: I cloud, Gmail, Hotmail etc.

3. Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)

4.  External cloud or multitenant cloud
Allows systems and services to be
easily accessible to the general
public
Example Google, Amazon,
Microsoft

5.  Internal Cloud or on-premises
Cloud
 allows systems and services to
be accessible within an
organization

6.  Allows system and services
to be accessible by group of
organizations
 Managed internally or by the
third-party.

7.  Mixture of public and private
cloud
 Critical activities are
performed using private cloud
 Non-critical activities are
performed using public cloud.

8.  Infrastructure as a service (IaaS)
 Platform as a service (PaaS)
 Software as a service (SaaS)

9.  Resources are distributed as a service
 Has a variable cost utility pricing model
 Multiple users on a single piece of hardware

10.  PaaS provides built-in security,
scalability, and web service interfaces.
 PaaS provides built-in tools for defining
workflow and approval processes and
defining business rules.
 Easy to integrate with other applications
on the same platform.
 PaaS also provides web services
interfaces that allow us to connect the
applications outside the platform

11.  Managed from Central Location
 Web access to commercial software
 Delivered in one to many model

12. 1. Client computers
2. Distributes servers
3. Datacenters

13. It is collection of servers where
application is placed and is
accessed via internet.
Often servers are in geographically
different places, but server acts as if they
are working next to each other.

14.  Social Networking sites.
 E-mail sites.
 Search Engines.
 Many more services OVER THE INTERNET.

15.  Unwarranted service charges.
 Adverse impact of mishandling of data.
 General security concerns.
 Data recovery and confidentiality problems.
 Financial or legal problems.

16.  On demand self service
 Cost effective
 No software required
 More Reliable

17.  Reduce the complexity of networks.
 Do not have to buy software licenses.
 Information at cloud are not easily lost.
