INTRODUCTION:-

•

Cloud computing, a new kind of computingmodel.

• It is an extend of changing with the need, that

is to say the manufacturer provide relevanthardware software and service according to

the need that users put forward.

•

provide secure, quick convenient data storageand net computing service centered by

internet.



ClOUD:-

• It is not an invention, but more of a “practical

innovation”, combining several earlier inventions into

something new and compelling.

• Cloud computing:- Cloud Computing is a popular

phrase that is shorthand for,applications that were

developed to be rich Internet applications,that run

on the Internet (or “Cloud”).



ITS PRINCIPLE:-

• Users can buy the computing resource through

internet according to their own needs.

• VIRTUALISATION

• DYNAMISM

• ABSTRACTION

• AUTOMATION

• RESOURCE SHARING



The Anatomy of the Cloud

Virtualization is abstracting thehardware to run virtual instances of

multiple guest operating systems on a

single host operating system. You can

see Virtualization in action by installing

Microsoft Virtual PC, VMware Player

or Sun VirtualBox. These are desktop

virtualization solutions that let you

install and run an OS within the host

OS. The virtualized guest OS images

are called Virtual Machines. The

benefit of virtualization is realized

more on the servers than on the

desktops.



Virtualization on the

Server:-

In fact, in the servervirtualization scenario, thehost OS is not very significant.It is just confined to bootingup and running the VMs.Given the fact that the OS isnot ideal for running multipleVMs and has a little role toplay, there is a new breed of software called Hypervisorthat takes over the OS.Hypervisor is an efficientVirtual Machine Manager

(VMM) that is designed fromthe ground up to run multiplehigh performant VMs. So, aHypervisor is to VMs what anOS is to processes.



VIRTUAL MACHINE:-

This is the layer that you willdirectly interact with. InPlatform as a Service (PaaS),you may not realize that youare dealing with a VM but inreality most of the Cloudimplementations will host your

code or app on a VM. VMs areessential to respect the 4 tenetsof the Cloud. Your applicationruns on a VM that is managedby the Hypervisor runningacross all the servers. These

VMs are moved across servers

based on the server utilization.There is no guarantee that theVM that you launch

will run on the same physicalserver.



AMAZON WEB SERVICE



SIMPLE STORAGE SERVICE

Amazon’s Simple StorageService or S3 is a great way to

store data on the Cloud that

can be accessed by any

application with access to the

Internet. S3 can store any

arbitrary data as objectsaccompanied by metadata.

These objects can be

organized into buckets. Every

bucket and object has a set of

permissions defined in the

Access Control List (ACL). The

objects stored in S3 can be

anything from a document, a

media file, serialized objects

or even Virtual Machine

images.



EC2

In simple terms, EC2 ishiring a server running at a

remote location. These

servers are actually Virtual

Machine images running

on top of Amazon’s powerful data centers.

Amazon calls these

virtualized server instances

as Amazon Machine

Images or AMI.



SQS & Cloud front



CLOUD COMPUTING:-



STYLE:-• SAAS(Software as a service)

•This is the Top most layer of the cloud computing stack -directly consumed by end user – i.e. SaaS (Software as a

Service).

• On-Premise applications are quite expensive, affordable only

to big enterprises. Why?• Now, they can afford best software solution for their business

without investing anything at all on the infrastructure or

development platform or skilled manpower. The only

requirement for SaaS is a computer with browser, quite basic.

SaaS is a recurring subscription based model delivered to

customer on demand – Pay as you use.



PAAS

• Now you don’t need to invest millions of $$$ to get that

development foundation ready for your developers. The PaaS

provider will deliver the platform on the web, and in most of

the cases you can consume the platform using your browser,

i.e. no need to download any software. It has definitelyempowered small & mid-size companies or even an individual

developer to launch their own SaaS leveraging the power of

these platform providers, without any initial investment.

• Design,development,testing,deployment and hosting



IAAS:-

• This is the base layer of the cloud stack.

• It serves as a foundation for the other two layers, for theirexecution. The keyword behind this stack is Virtualization.

• Let us try to understand this using Amazon EC2. In Amazon

EC2 (Elastic Compute Cloud) your application will beexecuted on a virtual computer (instance). You have the choiceof virtual computer, where you can select a configuration of CPU, memory & storage that is optimal for your application.The whole cloud infrastructure viz. servers, routers, hardware

based load-balancing, firewalls, storage & other network equipments are provided by the IaaS provider. The customerbuy these resources as a service on a need basis.



ITS CHARACTERISTICS:-

Self-healing

Scalable

Governed by a Service Level Agreement

Multipurpose



ADVANTAGES:

Reduced Cost:-

More Storage:-

Automatically Updated :-

No Downloads

Shared Resources



DISADVANTAGES:-

It’s not secure

It’s not platform agnostic

Reliability is still an issue

Portability isn’t seamless It’s not environmentally sustainable



Cloud computing future:- industry trends:

• 1.Cloud computing is widening, but focus on an open platform mainly.

• 2. Windows Azure is mostly a better platform of Exchange.

• Google would increase the area of investment in theenterprise, more business users will use

Google Apps.

• 4. The first batch of SaaS 1.0 companies will face the risk of bankruptcy.

• 5. The number of firms who abandon the use of its own server increased significantly.



• 6. Private cloud computing services have been popular.

•

• 7. Business Intelligence (BI) will be SaaS's next target.

•

• 8. SAP or Oracle will enter PaaS (Platform as a Service, PaaS, Platform as a service) area.

•

• 9. Enterprise adoption and use of social networks faster.

•

• 10. Force.com the creation of software products worth at least 1 billion dollars

PUBLIC CLOUD

Offer the full range of benefitsand features that come with

cloud computing: agility,

flexibility, elasticity, and on-

demand abilities. They are run

off-site by third parties, and the

cost savings are hard to beat. Aslong as you have Internet access

and a compatible device the

cloud can be accessed from

anywhere. Simply the purchase

the resources you need (hard

drive space, processing power)

and switch them off when you

no longer have use for them. No

contract, no commitment, and

no fuss.



PRIVATE CLOUD

Run on private networksand as such offercustomers a range of

enhanced featuresincluding increased datasecurity and improved

manageability. A

private cloud is owned by asingle customer who is incontrol of when and where

applications run, and who

uses the infrastructure.They own the server andbuild and

maintain the network.



HYBRID CLOUD

There are scenarios where you need acombination of Private Cloud and

Public Cloud. Due to the regulations

and compliance issues in few

countries, sensitive data like citizen

information, patient medical history,

and financial transactionscannot be

stored in servers that physically not

located within the political

boundaries of a country. In some

scenarios, the enterprise customers

want to get

best of the both worlds by logically

connecting their Private Cloud and the

Public

Cloud. Through this, they can offer

seamless scalability by moving some of

the onpremise

and Private Cloud based applications

to the Public Cloud.



First move on cloud:-

1. Amazon

Specializes in IaaS. It offers through Amazon Web Services

(AWS): Amazon Elastic Compute Cloud(EC2),

Amazon SimpleDB, Amazon CloudFront, Amazon SQS. It

claims to have 82 billion objects stored in Amzon S3 (Simple

Storage Service)!

2. Google.

Specializes in PaaS & SaaS. As SaaS it offers Google Apps: a

web-based communication, collaboration & security apps

which includes, Gmail, Google Calendar, Google Talk, Google

Docs & Google Sites



3. VMware

It offers vCloud: Run, secure and manage applications in theprivate cloud or have them federated on-demand to partner-hosted public clouds. vCloud is giving a tough competition to

more established Amazon’s AWS. 4. Rackspace

The company specializes in IaaS. It offers Rackspace Cloud,cloud services are: Cloud Sites, Cloud Servers, Cloud Files.

5. Salesforce.comLeader in SaaS. Offers Salesforce CRM (Sales Cloud 2, ServiceCloud 2) & Force.com Platform (Custom Cloud 2,Development Platform).

Conclusion:-

• Among the many IT giants driven by trends in cloud computing has not

doubtful. It gives almost everyone has brought good news. For enterprises,

cloud computing is worthy of consideration and try to build business

systems as a way for businesses in this way can undoubtedly bring about

lower costs, higher profits and more choice; for largescale industry, After

the financial turmoil will be the cost of infrastructure for large-scalecompression seems likely; developers, when in the face of cloud

computing, through the PaaS model can effectively improve their own

capacity,Therefore, the impact of cloud computing on the ISV is the largest

of the many roles; for engineers and developers are concerned, the advent

of cloud computing will shrink to the development of comprehensiveWebcentric development, so that a lot of complex technology to reduce the

learning accelerated the pace of career development. There is the advent of

cloud computing is bound to birth a number of new jobs.
