Introduction• To theoretically define Cloud

computing :

It is Internet-based computing,

whereby shared resources,

software and information are

provided to computers and other

devices on-demand.

• In simple words it can be said as a

System, Platform or even an OS.Fig: Basic concept



What is cloud computing?• “Cloud” is actually a metaphor for the Internet. • Knowledge about controls and ownership in

computer infrastructure is not needed by the user.

• Users simply rent or access the software, payingonly for what they use.

“Cloud computing is using the Internet to access someone else’s software running onsomeone else’s hardware in someone else’s data centre while paying only for what youuse.”



Architecture Cloud computing actually has two

layers.

One is front end and other is back end. They connect to each other through

a network, usually the Internet.

The assumption in architecture is thatthe demand for resources is not always

consistent from client to cloud.



Front End & Back EndFRONT END BACK END

•Client use

•Applications needed to access the

cloud system.

•All cloud systems do not givesame interface to users.

• Front end is a technical term .

•Refers to the interface though

which a user can use some kind of services.

•Refers physical peripherals.

•It is cloud itself.

•Monitor’s client’s demand.

• Back end is cloud itself whichmay encompasses of various

computer machines.



Characteristics



Dynamic computing

infrastructure.

Foundation of this infra is

standardized, scalable & secure

infrastructure. The infra should be virtualized to

run various services.

Finally, the infrastructure must be

utilized.

This dynamic infra is important

for elasticity of cloud computing.

• Cloud computing is service-

centric.

• This provides advantage of not

to bogged down in systemadministration.

• By, help of this user can easily

access pre-defined computing

environments.

• An IT-server centric view

enables user adoption &

business agility.

• Reduces cost, makes faster

operations.

IT service-centric

approach.



Self-service based

usage model.

•Interacting with cloud

requires self-service.

•The best thing is that it

provides users the ability toupload, build, schedule,

manage, and report on their

business services.

•More self-service providedless administrative

involvement required.

•Saves Time & Money.

Consumption-based

billing.

•Cloud-computing is user-

driven.

•It must have mechanism

that can capture usage info.•Pro’s are that user only pay

for what he/she uses.

•This keep’s cost down.

•From provider’s view thishelps them to track usage

info. & thus charge back the

user accurately.



Cloud Patterns

•PRIVATE CLOUD:

Private cloud (also

called internal cloud orcorporate cloud) is a

marketing term for a

proprietary computing

architecture that

provides hosted servicesto a limited number of

people behind a firewall.



Cloud Patterns

•PUBLIC CLOUD

This is

provided by athird-party

provider.

It is self-

service based

and consideredthe most

traditional cloud

pattern.



Cloud Patterns

•HYBRID CLOUD

A hybrid storage cloud

uses a combination of public and private storage

clouds.

Hybrid storage clouds

are often useful forarchiving and backup

functions.



Cloud Patterns

•COMMUNITY

CLOUD

Established whereseveral organization

require similar needs.

More expensive pattern.

Offer a higher level

of privacy, security and/or policy

compliance.



Intercloud

•Intercloud is

interconnected

global cloud of

clouds.• This cloud have

dimension of one

machine having

several servers.

•But, still it raisesmany security, legal

and billing concept.



Pros & Cons

PROS:

Lower computer

costs

Improvedperformance

Better storage

capacity

CONS:Stored data

might not be

secure



Conclusion

• Cloud computing is an emerging computingtechnology that uses the Internet and central

remote servers to maintain data and

applications.

•Gives us the Ease of use.•Provides high Scalability.

•It prevents the most dangerous phobia of

MONEY!! I.e. Economical.

•It simple words we can conclude that it gives

us a way to trend away from the PAIN!!
