Cloud computing is a type of computing that relies on sharing computing resources over the Internet instead of having local servers or devices handle applications. It allows users to access software, storage, and other computing services from anywhere via cloud servers. There are three main types of cloud services: Infrastructure as a Service (IaaS) which provides on-demand access to computing infrastructure resources; Platform as a Service (PaaS) which provides platforms and environments for developing and delivering applications; and Software as a Service (SaaS) which provides software applications delivered over the Internet. Cloud computing provides scalable, cost-effective, and collaborative computing resources on demand.

Utility implies pay-per-use service
Demand implies ~infinite, ~immediate, ~invisible scalability

4. • Cloud computing is a type of computing that relies on sharing
computing resources rather than having local servers or
personal devices to handle applications.
• In cloud computing, the word cloud (also phrased as "the cloud")
is used as a metaphor for "the Internet," so the phrase cloud
computing means "a type of Internet-based computing" where
different services such as servers, storage and applications are
delivered to an organization's computers and devices through
the Internet.
• So Cloud Computing is where software applications due to data
storage and processing power capacity are accessed over the
internet using cloud servers instead of dedicated servers.
1. What is Cloud Computing?

5. Computing and software resources that are delivered
on demand, as service..

6. 2. Cloud Architecture
•Individual users connect to the cloud
from their own personal computers or
portable devices, over the Internet.To
these individual users, the cloud is
seen as a single application, device, or
document.
•The hardware in the cloud (and the
operating system that manages the
hardware connections) is invisible.

8. 1- Public Cloud
It is owned and managed by
service provider and made
available to the general public
or a large industry group
2- Private Cloud
It is operated solely for an
organization and may be
managed by the organization or
by a third party. It limits access
to enterprise and partner
network and retains high
degree of control, privacy and
security
3- Hybrid Cloud
Composition of two or more
clouds (private or public)
bound together by
standardized or proprietary
technology that enables data
and application portability

11. There are mainly 3 service
models given as:
1. Software as a Service (SaaS)
2. Platform as a Service (PaaS)
3. Infrastructure as a Service
(IaaS)

12. Architectural Layers of Cloud Computing

13. •SaaS is a software delivery methodology that
provides licensed multi-tenant access to
software and its functions remotely as a
Web-based service.
Software as a
Service (SaaS)
•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.
Platform as a
Service (PaaS)
•IaaS is the delivery of technology
infrastructure as an on demand scalable
service.
Infrastructure as
a Service (IaaS)

14. •Accessible from any computer
•Sometimes free; easy to use; good consumer
adoption; proven business models
Software as a
Service (SaaS)
• Highly scalable; multi-tier architecture; Multi
tenant environments
• Developers can upload a configured applications
and it “runs” within the platform’s framework
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)

18. Cloud Computing is the fastest growing part of
network based computing . It Provides tremendous
benefits to customers of all sizes: simple users,
developers, enterprises and all types of organizations.
