What is Cloud Computing?.
• An environment created in a user’s machine from
an on-line application stored on the cloud and run
through a web browser.
• In simple Cloud computing is using the internet to
access someone else's software running on someone
else's hardware in someone else's data center.
Cloud Computing Services
► Software

as a Service (SaaS)-End Users

► Platform

as a Service (PaaS)-Application
Developers

► Infrastructure

Architects

as a Service (IaaS)-Network
The NEW “Cloud Pyramid”
Software as a Service-End Users
►

Just run it for me!

►

also known as On-demand Service.

►

is an application that can be accessed from anywhere on the
world as long as you can have an computer with an Internet
Connection.

►

We can access this cloud hosted application without any
additional hardware or software.

►

E.g. : G-mail, Yahoo mail, Hotmail etc..,

►

Also they can provide security features such as SSL encryption,
a cryptographic protocol.
Application provided by Cloud Computing –
Google Cloud
Platform as a Service (PaaS)Application Developers

►

Give us nice API (Application Programming Interface) and take
care of the implementation.

►

In the PaaS model, cloud providers deliver a computing platform
and/or solution stack typically including operating system,
programming language execution environment, database, and
web server.

►

is a platform for developers to write and create their own SaaS
i.e. applications.

►

which means rapid development at low cost.

►

E.g.: Salesforce.com, Windows Azure etc.
Infrastructure as a Service (IaaS)Network Architect
►

also known as hardware as a service.

►

is a computing power that you can rent for a limited period of
time.

►

allows existing applications to be run on a cloud suppliers
hardware.

►

cloud providers offer computers – as physical or more often as
virtual machines – raw (block) storage, firewalls, load balancers,
and networks
Cloud Architecture
Modes of Clouds
Public Cloud
► Computing infrastructure is hosted by cloud vendor at the vendors
premises.
► and can be shared by various organizations.
► E.g. : Amazon, Google, Microsoft, Sales force
Private Cloud
► The computing infrastructure is dedicated to a particular organization
and not shared with other organizations.
► more expensive and more secure when compare to public cloud.
► E.g. : HP data center, IBM, Sun, Oracle, 3tera
Hybrid Cloud
► Organizations may host critical applications on private clouds.
► where as relatively less security concerns on public cloud.
► usage of both public and private together is called hybrid cloud.
Cloud Operating Systems
► Eye

OS
► Amoeba OS
► Glide OS
► Start force
► myGoya
► CorneliOS
► Lucid Desktop
► Cloudo, Ghost, Zimdesk, Start force etc.,
Some other Applications
are:
Audio Player
Ever note Viewer
Video Player
Media Player
Flash Player
Google Document Viewer
Messenger
Sticky Note
Web Browser Lite

Is Cloud Computing reduces E-Waste?.
► Green

IT Cloud Computing

► Cloud

Computing is Eco-Friendly.

► We

can reduce E-waste by using Cloud
Computing i.e. by Infrastructure as a Service
(IaaS).

► Cloud
► Can

Computing Helps to Accelerate Green IT

reduce Global Warming too..

Disadvantages of Cloud Computing
►

Cloud computing is impossible if you cannot connect to the
Internet.

►

Since you use the Internet to connect to both your applications
and documents, if you do not have an Internet connection you
cannot access anything, even your own documents.

►

A dead Internet connection means no work and in areas where
Internet connections are few or inherently unreliable, this could
be a deal-breaker.

►

When you are offline, cloud computing simply does not work.
