3. Introduction
Cloud Computing provides us a means by
which we can access the applications as
utilities , over the Internet.
It allows to create , configure , and customize
applications online.
With cloud computing users can access
database resources via internet from
anywhere for as long as they need without
worrying about any maintenance
management of actual resoursces.

4. What is cloud?
The term cloud refers to
“Network” or “Internet”.
Cloud can provide services over
network, i.e., on public
Network or an private network
Like that:-
WAN,LAN orVPN.

6. What is cloud computing?
Cloud Computing refers to manipulating,
Configuring , and accessing application
online.
It offers online data storage, infrastructure
and application.
Cloud computing is both a combination of
software and hardware based computing
resources delivered as a network service.

7. Cloud Computing Architecture

8. Basic concepts
 There are certain services and models
working behind the scene making the
cloud computing feasible and accessible
to end users.
 Working models for cloud computing:-
1.Deployment models
2.Service models

9. Deployment Models
Deployment models define “How the cloud is
located”?
Cloud can have any of the 4 types to access:
a) Public cloud:- It allows services to be easily
accessible to the general public.
b) Private cloud:- It allows services to the
accessible within organization.
c) Community cloud:- it allows services to be
accessible by group of organization.
d) Hybrid cloud:- it is a mixture of public and
private cloud.

10. Servicemodel
Service model are the reference models on which cloud is based.
These can be categorized into three basic service models as
instead below:
1. Infrastructure as a services(IaaS
2. Platform as a service (PaaS)
3. Software as a service(Saas)

11. IaaS, PaaS, SaaS
 IaaS:- IaaS is the delivery of technology
infrastructure as an on demand scalable
service.
It provides access to fundamental resources
such as physical machine, virtual storage , etc.
 PaaS:- PaaS provide the runtime environment
for application , development & deployment
tools, etc.
 Saas:- SaaS model allows to use software
application as a service to end users.
Highly scalable architecture.

13. Some Examples

14. Advantages
 Lower computer costs
 Improved performances
 Reduce software cost
 Unlimited storage capacity
 Device independence
 Latest version availability

15. Disadvantages
 Requires a constant internet connection
 Does not work well low-speed connection
 Features might be limited
 Stored data can be lost
 Stored data might not be secure
