INTRODUCTION

What is CLOUD COMPUTING?

Cloud computing is an emerging computingtechnology that uses the internetand central remote servers to maintain data andapplications.


4/21

CLOUD COMPONENTS


5/21

Clients

Clients are the devices that the end user interact with tomanage their information on the cloud.Types of clients:- Mobile Thin Thick


6/21

Datacenter

The data center is a collection of servers where theapplication to which you subscribe is housed.VIRTUALIZING SERVERSA software can be installed allowing multiple serverinstances on a single physical machine(or server).


7/21

Distributed Servers

Servers at geographically disparate locations.Advantages:- In case of failure Resource extension


8/21

Cloud Computing and Virtualization

What is Virtualization ?"Virtualization,in computing, is a technique of creating avirtual rather than an actual version of something."

Types of Virtualization:- Full Virtualization Paravirtualization


9/21

Full VirtualizationFull Virtualization is a virtualization technique used

to provide a certain kind of virtual machineenvironment.

10/21

The result is a system inwhich all software running onthe server is within a virtualmachine.Highlights:- Sharing Isolation Emulation


11/21

ParaVirtualizationIt is a virtualization technique that allows operating systems

to run on a single hardware device at the same time by moreefficiently using system resources.


12/21

Types of CLOUD

o Public Cloud:public for purchase, resale etc.o Private Cloud:privately owned by organisationo Hybrid Cloud:software+services


13/21

SERVICES

It is a concept of being able to use resuable, fine-grained

components across a vendor's network.


14/21

Infrastructure as a service(IaaS)servers,routers,hardware based load-balancing,firewalls,storage and other n/w equipments.Software as a service(SaaS)applications hosted as a service, accessed via internet bythe customers.Platform as a service(PaaS)

resources required to build applications and servicescompletely from the internet.


15/21

CLOUD V/S GRID COMPUTING

Grid Computing

A large project is divided among multiple computers tomake use of their resources to complete the project(ortask).

Cloud ComputingOpposite to grid computing.It allows multipleapplications to run on a single machine.


16/21

SECURITY

The relative security of cloud computing services is acontentious issue which may be delaying its adoption.Some argue that customer data is more secure when

managed internally, while others argue that cloudproviders have a strong incentive to maintain trust andas such employ a higher level of security.


17/21

Why Cloud Computing ?

Pay per Use Instant scalability Security Reliability APIs


18/21

CONCLUSION

Cloud computing is a better way to run yourbusiness. Instead of running your appsyourself, they run on a shared data center.

When you use any app that runs in the cloud,you just log in, customize it, and start using it.Thats the power of cloud computing.

Finally, cloud apps dont eat up your valuable IT

resources. This lets you focus on deployingmore apps, new projects..........
