What is a cloud ??
 Abstraction
- Use something without knowing what is going on inside.
- Users are shielded from the details how something actually works.

An example of abstraction…
Key
Steering wheel
Gearshift
Gas pedal
Brakes
We seldom worry about the thousands of highly specialized parts that are combined to produce the car…!

Cloud !!
A Cloud depicts the Internet in computer network as an abstraction of the underlying infrastructure it represents.

Internet

A collection or groups of integrated and networked
hardware,
software and
internetworking infrastructure
INTERNET
provides
hardware,
software and
networking services toEnd Clients

Third-party Provider
Customers
Cloud computing customers do not own the physical infrastructure.
They consume resources as a service.
The service is fully managed by the provider.
The consumer only needs a personal computer and Internet access.

Three layers to cloud computing…
Companies use these layers differently based on what they offer.

Hosting in the cloud

“HOSTING”
COSTS HIGH CONSUMES A LOT OF TIME

Youpay for them when you are using them, and
You pay for them when your not using them…

And the more you pay on their maintenance…

CLOUD COMPUTING OFFERS
PLATFORMS
SERVICES
STORAGE SPACE
APPLICATIONS

Scalability !!

INSTANT !!

How does it work ???
No need of running heavy servers and maintaining them.
Instead, run applications on a shared data centers.
Just plug in to the shared data servers just like using a utility.
Its fast to get started and costs less.

When using any application in the cloud, the client just needs to log in to his account; just like any other application and access his resources!!

CLOUD COMPUTING

Types of Clouds
Public
Resources are dynamically provisioned on a self-service basis.
Provided by an off-site third-party provider who shares resources and bills utility computing basis.
Private
Capitalise on data security, corporate governance, and reliability concerns.
Users "still have to buy, build, and manage clouds“
lacks the economic model that makes cloud computing such an intriguing concept.
Hybrid
A hybrid cloud environment consists of multiple internal and/or external providers.

ADVANTAGES OF CLOUD COMPUTING
Servers and Storage
ELIMINATES HASSELES OF ESTABLISHING PHYSICAL INFRASTRUCTURE

INCREASED RELIABILITY
DEVICE INDEPENDANCY
UNLIMITED STORAGE
REMOTE ACCESS
ECO-FRIENDLY
ECONOMICAL

FACILITATES COLLABORATIONS
ENABLES US TO SHIFT FOCUS
ALL TIME DATA AVAILABILITY
IMPROVED PERFORMANCE
HIGHLY AUTOMATED
EASILY SCALABLE
MORE MOBILITY
SECURITY

DISADVANTAGES OF CLOUD COMPUTING
TOTALLY INTERNET CONNECTION
ORIENTED
REQUIRE HIGH BANDWIDTH OF
NET CONNECTION
VENDOR DEPENDANC FOR DATA
MAINTENANCE

SECURITY (DATA TRANSPIRANCY)

HIGH BUDGET TO ESTABLISH CLOUD
COMPUTING ENVIRONMENT
NOT ACCESSIBLE BY EVERYONE
CHANCES OF FRAUDANESS
HUGE POWER IS REQUIRED

CHALLENGES OF CLOUD COMPUTING
TO FIND HIGH NETWORK AVAILABILITY
DATA MANAGEMENT
LINEARLY SCALABLE
DATA SECURITY (AVAILABILITY,CONFIDENTIALITY)
N

CHALLENGES OF CLOUD COMPUTING
CONTROL OF OUR DATA IS TRANSFERRED TO THIRD PARTY
BUSINESS FAILS IF SUPAILSPLIER GOES BANKRUPT
COMPETITOR CAN KNOW OUR BUSINESS EASILY AS DATA IS IN CLOUD

FINDINGS
Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet.
The future for cloud computing is bright. The big names in computers are throwing lots of resources into this.

FINDINGS
Platforms provide an on demand, always on, anywhere, anytime and any place, pay as used and as needed.
The whole idea behind it is resizable computing power. When you need the power, it's there, but when you don't, you can scale back.

FINDINGS
CLOUD COMPUTING CAN BE USED AS MOBILE TREND IF INTERNET FACILITY BECOMES EASY

LATEST UPDATE
MICROSOFT MADE A CLOUD BASED OS…
8TH MARCH 2010

CONCLUSION
HAS GOOD HARDWARE MANAGEMENT
SECURITY IS ADVANTAGE AS WELL AS THREAT
MADE BUSINESS LIFE EASY
HOWEVER NOT AVAILABLE TO ALL

CONCLUSION
USE OF IT DEPEND ON THE TYPE OF BUSINESS IS DONE
FLEXIBLE IN TERMS OF DATA AVAILABILITY AND RESOURCE USABILITY
HUGE DATA AVAILABILITY BUT MAINTENANCE IS A CHALLENGE

CONCLUSION
There are a lot of criticisms about the security in cloud computing.
Some have said stored information in the cloud is safer than on premise, but others disagree.
