Innovation is necessary to ride the inevitable tide of change. Indeed,
the success of the transformation of IBM to an On Demand Business
depends on driving the right balance of productivity, collaboration,
and innovation to achieve sustained, organic top line growth ”
and bottom line profitability.

Enterprises strive to reduce computing costs. Many start by
consolidating their IT operations and later introducing virtualization
technologies. Cloud computing takes these steps to a new level and
allows an organization to further reduce costs through improved
utilization, reduced administration and infrastructure costs, and
faster deployment cycles. The cloud is a next

Generation platform that provides dynamic resource pools, virtualization, and high availability.

Cloud computing describes both a platform and a type of application. A
cloud computing platform dynamically provisions, configures,
reconfigures, and deprovisions servers as needed. Cloud applications
are applications that are extended to be accessible through the
Internet. These cloud applications use large data centers and powerful
servers that host Web applications and Web services.

Cloud computing infrastructure accelerates and fosters the adoption of innovations:

Enterprises are increasingly making innovation their highest priority.
They realize they need to seek new ideas and unlock new sources of
value. Driven by the pressure to cut costs and grow”
simultaneously”they realize that it™s not possible to
succeed simply by doing the same things better. They know they have to
do new things that produce better results. Cloud computing enables
innovation. It alleviates the need of innovators to find resources to
develop, test, and make their innovations available to the user
community. Innovators are free to focus on the innovation rather than
the logistics of finding and managing resources that enable the
innovation. Cloud computing helps leverage innovation as early as
possible to deliver business value to IBM and its customers.

Fostering innovation requires unprecedented flexibility and
responsiveness. The enterprise should provide an ecosystem where
innovators are not hindered by excessive processes, rules, and resource
constraints. In this context, a cloud computing service is a necessity.
It comprises an automated framework that can deliver standardized
services quickly and cheaply.

Cloud computing infrastructure allows enterprises to achieve more efficient use of their IT hardware and software investments:

Cloud computing increases profitability by improving resource
utilization. Pooling resources into large clouds drives down costs and
increases utilization by delivering resources only for as long as those
resources are needed. Cloud computing allows individuals, teams, and
organizations to streamline procurement processes and eliminate the
need to duplicate certain computer administrative skills related to
setup, configuration, and support. This paper introduces the value of
implementing cloud computing. The paper defines clouds, explains the
business benefits of cloud computing, and outlines cloud architecture
and its major components. Readers will discover how a business can use
cloud computing to foster innovation and reduce IT costs.

DEFINITION:
INTRODUCTION

 The underlying concept of cloud computing dates back to 1960, when John McCarthy opined that "computation may someday be organized as a public utility"; indeed it shares characteristics with service bureaus that date back to the 1960s.
 The actual term "cloud" borrows from telephony in that telecommunications companies, who until the 1990s primarily offered dedicated point-to-point data circuits, began offering “VIRTUAL PRIVATE NETWORK (VPN)” services with comparable quality of service but at a much lower cost.
 The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider from that of the user. Cloud computing extends this boundary to cover servers as well as the network infrastructure.
 Cost is claimed to be greatly reduced and capital expenditure is converted to operational expenditure. Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using.
USES
 Helps to use applications without installations.
 Access the personal files at any computer with internet access.
 This technology allows much more efficient computation by centralizing storage, memory, processing and band width.
SURVEY
 Based on a study conducted in June 2009 by version one, 41% of IT senior professionals doesn’t have sound knowledge on cloud computing.
 In September 2009, Aberdeen Group found that 18% reduction in there IT budget and a 16% reduction in data center power costs.
LAYERS
APPLICATIONS

 Cloud application services or "Software as a Service (SaaS)" deliver ‘software’ as a service over the Internet, eliminating the need to install and run the application on the customer's own computers and simplifying maintenance and support.
PLATFORM
 Cloud platform services or "Platform as a Service (PaaS)" deliver a computing platform and/or solution stack as a service, often consuming cloud infrastructure and sustaining cloud applications. It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers.
INFRASTRUCTURE
SERVER

 The servers layer consists of computer hardware and/or computer software products that are specifically designed for the delivery of cloud services, including multi-core processors, cloud-specific operating systems and combined offerings
DEPLOYMENT MODELS
HYBRID CLOUD & PRIVATE CLOUD
CRITICISM

 Richard Stallman, founder of the Free Software Foundation and creator of the computer operating system GNU, said that cloud computing was simply a trap aimed at forcing more people to buy into locked, proprietary systems that would cost them more and more over time. "It's stupidity. It's worse than stupidity: it's a marketing hype campaign," he told The Guardian. "Somebody is saying this is inevitable – and whenever you hear somebody saying that, it's very likely to be a set of businesses campaigning to make it true." "The interesting thing about cloud computing is that we've redefined cloud computing to include everything that we already do," he said.
 The main drawback behind the concept of Cloud Computing is we can’t completely rely on third party when we are transmitting sensitive data.
ISSUES
LEGAL

 In March 2007, Dell applied to trademark the term "cloud computing" (U.S. Trademark 77,139,082) in the United States. The "Notice of Allowance" the company received in July 2008 was cancelled in August, resulting in a formal rejection of the trademark application less than a week later.
 Since 2007, the number of trademark filings covering cloud computing brands, goods and services has increased at an almost exponential rate. As companies sought to better position themselves for cloud computing branding and marketing efforts, “cloud computing trademark filings increased by 483% between 2008 and 2009.” In 2009, 116 cloud computing trademarks were filed, and trademark analysts predict that over “500 such marks could be filed during 2010.”
SECURITY
 The relative security of cloud computing services is a contentious issue which may be delaying its adoption. Some argue that customer data is more secure when managed internally, while others argue that cloud providers have a strong incentive to maintain trust and as such employ a higher level of security.
CONCLUSION
 Cloud computing is a better way to run your business. Instead of running your apps yourself, 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. That’s the power of cloud computing.
 Finally, cloud apps don’t eat up your valuable IT resources, so your CFO will love it. This lets you focus on deploying more apps, new project and implimentations, and innovation
THE BOTTOM LINE
Cloud computing is a simple idea, but it can have a huge impact on your business.

Abstract
Cloud Computing disrupts the conventional on-premises IT model, where you keep acquiring servers, PCs and software licenses as your business grows. Running application services on a cloud platform moves CapEx (capital expense) to OpEx (operational expense) , because business can develop, deploy and use more application services as they require them, without needing huge initial capital investments (and ensuing operational costs) for dedicated infrastructure that may never be needed.
The convergence of Grid and Cluster computing, Virtualization, Web Services and Service Oriented Architecture (SOA) offers the potential to set IT free from the costs and complexity of its typical physical infrastructure, allowing concepts such as Utility Computing to become at last meaningful. With the global economy in crisis, the timing could hardly be better for the technologies and services Cloud Computing provides, as IT managers are forced to make tough decisions and do more with less amount. Cloud Computing allows business to increase IT capacity (or add capabilities)on the fly and in real time (Internet-enabled), without investing in new infrastructure, training new personnel or licensing new software, and as a pay-per-use service(i.e.)you only pay what you “consume”.
Keywords--Cloud computing,Grid computing
I. INTRODUCTION:
Cloud computing describes both a platform and a type of application. A cloud computing platform dynamically provisions, configures, reconfigures, and deprovisions servers as needed. Cloud applications are applications that are extended to be accessible through the Internet. These cloud applications use large data centers and powerful servers that host Web applications and Web Services.
II. LIFE BEFORE CLOUD COMPUTING:
Before the invention of cloud computing, we have to install all the resources in our own personal computer and utilize it. Traditional business applications - like those from SAP, Microsoft, and Oracle - have always been too complicated and expensive. They need a data center with office space, power, cooling, bandwidth, networks, servers, and storage. A complicated software stack. And a team of experts to install, configure, and run them. They need development, testing, staging, production, and failover environments.

Cloud computing is a better way to run your business. Instead of running your apps yourself, 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. That’s the power of cloud computing. They cost less, because you don’t need to need to pay for all the people, products, and facilities to run them. Forget about buying servers and software.
III. WHY CLOUD COMPUTING:
Cloud Computing supports faster application development or deployment. It reduces hardware provisioning from months to hours. It provides standard platforms to encourage standardization. It is developing under security guidelines and reduces implementation delays to retrofit security. It reduces development and operating cost. Its Self-service model, Standardization and Centralization of resources in the cloud reduces cost. It improves overall security posture. There is an unquenchable thirst for collaboration and sharing. We can work anywhere at any time highly mobile workforce. You can work wherever you are at home, traveling etc.
IV. CLOUD COMPUTINGTongueAY FOR INNOVATION NOT INFRASTRUCTURE
•Scenario without Cloud Computing: wait until the purchase request is approved, wait until the servers arrive, wait until the servers are configured, etc. all of which can take several weeks or even several months. Let's say it takes three months. In an industry where the cost of delaying a product is estimated at $150 per second, that three months' wait would cost more than $1 billion.
• Scenario with Cloud Computing: the researcher clicks over to Amazon Web Services, configures the 25 servers in the Cloud in one hour, and within two hours has crunched the data. Total fee for the time using Amazon’s resources? Just $89.
A)The five characteristics:
• On-demand self-service: individuals can set themselves up without needing anyone’s help;
• Ubiquitous network access: available through standard Internet-enabled devices;
• Location independent resource pooling: processing and storage demands are balanced across a common infrastructure with no particular resource assigned to any individual user
• Rapid elasticity: consumers can increase or decrease capacity at will;
• Pay per use: consumers are charged fees based on their usage of a combination of computing power, bandwidth use and/or storage
B)The possible delivery models:
• Cloud Software as a Service (SaaS): Customers rent software hosted by the vendor;
• Cloud Platform as a Service (PaaS): Customers rent infrastructure and programming tools hosted by the vendor to create their own applications;
• Cloud Infrastructure as a Service (IaaS): Customer rent processing, storage, networking and other fundamental computing resources for all purposes.

Cloud Computing


.docx   Cloud Computing.docx (Size: 1.03 MB / Downloads: 24)

INTRODUCTION

Cloud computing is the next natural step in the evolution of on-demand information technology services and products. To a large extent cloud computing will be based on virtualized resources. The idea of cloud computing is based on a very fundamental principal of `reusability of IT capabilities`. The difference that cloud computing brings compared to traditional concepts of grid computing, distributed computing,utility computing, or autonomic computing is to broaden horizons across organizational boundaries. Though many cloud computing architectures and deployments are powered by grids, based on autonomic characteristics and consumed on the basis of utilities billing, the concept of a cloud is fairly distinct and complementary to the concepts of grid, SaaS, Utility Computing etc. In theory, cloud computing promises availability of all required hardware, software, platform, applications, infrastructure and storage with an ownership of just an internet connection. People can access the information that they need from any device with an Internet connection—including mobile and handheld phones—rather than being chained to the desktop. It also means lower costs, since there is no need to install software or hardware.‖

Characteristics of Cloud Computing

Self Healing

Any application or any service running in a cloud computing environment has the property of self healing. In case of failure of the application, there is always a hot backup of the application ready to take over without disruption. There are multiple copies of the same
application - each copy updating itself regularly so that at times of failure there is at least one copy of the application which can take over without even the slightest change in its running state.

Multi-tenancy

With cloud computing, any application supports multi-tenancy - that is multiple tenants at the same instant of time. The system allows several customers to share the infrastructure allotted to them without any of them being aware of the sharing. This is done by virtualizing the servers on the available machine pool and then allotting the servers to multiple users. This is done in such a way that the privacy of the users or the security of their data is not compromised.

Linearly Scalable

Cloud computing services are linearly scalable. The system is able to break down the workloads into pieces and service it across the infrastructure. An exact idea of linear scalability can be obtained from the fact that if one server is able to process say 1000 transactions per second, then two servers can process 2000 transactions per second.

Service-oriented

Cloud computing systems are all service oriented - i.e. the systems are such that they are created out of other discrete services. Many suchdiscrete services which are independent of each other are combined together to form this service. This allows re-use of the different services that are available and that are being created. Using the services that were just created, other such services can be created.

SLA Driven

Usually businesses have agreements on the amount of services. Scalability and availability issues cause clients to break these agreements. But cloud computing services are SLA driven such that when the system experiences peaks of load, it will automatically adjust itself so as to comply with the service-level agreements. The services will create additional instances of the applications on more servers so that the load can be easily managed.

Virtualized

The applications in cloud computing are fully decoupled from the underlying hardware. The cloud computing environment is a fully virtualized environment. Virtualization is another very useful concept. It allows abstraction and isolation of lower-level functionalities and underlying hardware. This enables portability of higher-level functions and sharing and/or aggregation of the physical resources. The virtualization concept has been around in some form since 1960s (e.g., in IBM mainframe systems). Since then, the concept has matured considerably and it has been applied to all aspects of computing – memory, storage, processors, software, networks, as well as services that IT offers. It is the combination of the growing needs and the recent advances in the IT architectures and solutions that is now
bringing the virtualization to the true commodity level. Virtualization, through its economy of scale, and its ability to offer very advanced and complex IT services at a reasonable cost, is poised to become, along with wireless and highly distributed and pervasive computing devices, such as sensors and personal cell-based access devices, the driving technology behind the next waive in IT growth .

Need for Cloud Computing

What could we do with 1000 times more data and CPU power? One simple question. That’s all it took the interviewers to bewilder the confident job applicants at Google. This is a question of relevance because the amount of data that an application handles is increasing day by day and so is the CPU power that one can harness. There are many answers to this question. With this much CPU power, we could scale our businesses to 1000 times more users. Right now we are gathering statistics about every user using an application. With such CPU power at hand, we could monitor every single user click and every user interaction such that we can gather all the statistics about the user. We could improve the recommendation systems of users. We could model better price plan choices. With this CPU power we could
simulate the case where we have say 1,00,000 users in the system without any glitches.
There are lots of other things we could do with so much CPU power and data capabilities. But what is keeping us back. One of the reasons is the large scale architecture which comes with these are difficult to manage. There may be many different problems with the architecture we have to support. The machines may start failing, the hard drives may crash, the network may go down and many other such hardware problems.

CLOUD ARCHITECTURE AND TYPES

ARCHITECTURE

Cloud architecture the systems architecture of the software systems involved in the delivery of cloud computing, comprises hardware and software designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services. This closely resembles the Unix philosophy of having multiple programs doing one thing well and working together over universal interfaces. Complexity is controlled and the resulting systems are more manageable than their monolithic counterparts. Cloud architecture extends to the client, where web browsers and/or software applications access cloud applications. Cloud storage architecture is loosely coupled, where metadata operations are centralized enabling the data nodes to scale into the hundreds, each independently delivering data to applications or users.

COMPONENTS AND WORKING

Components

The key to a SOA framework that supports workflows is componentization of its services, an ability to support a range of couplings among workflow building blocks, fault-tolerance in its data- and process-aware service-based delivery, and an ability to audit processes, data and results, i.e., collect and use provenance information. Component-based approach is characterized by reusability (elements can be re-used in other workflows), substitutability (alternative implementations are easy to insert, very precisely specified interfaces are available, run-time component replacement mechanisms exist, there is ability to verify and validate substitutions, etc), extensibility and scalability (ability to readily extend system component pool and to scale it, increase capabilities of individual components, have an extensible and scalable architecture that can automatically discover new functionalities and resources, etc),customizability (ability to customize generic features to the needs of a particular scientific domain and problem), and composability (easy construction of more complex functional solutions using basic components, reasoning about such compositions, etc.). There are other characteristics that also are very important. Those include reliability and availability of the components and services, the cost of the services, security, total cost of ownership, economy of scale, and so on.In the context of cloud computing we distinguish many categories of components. From differentiated and undifferentiated hardware, to general-purpose and specialized software and applications, to real and virtual ―images‖, to environments, to no-root Differentiated resources, to workflow-based environments and collections of services, and soon.

CONCLUSION

Cloud computing builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. It implies a service oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, ondemand services and many other things.
In today's global competitive market, companies must innovate and get the most from its resources to succeed. Cloud computing infrastructures are next generation platforms that can provide tremendous value to companies of any size. They can help companies achieve more efficient use of their IT hardware and software investments and provide a means to accelerate the adoption of innovations.Cloud computing increases profitability by improving resource utilization. Costs are driven down by delivering appropriate resources only for the time those resources are needed. Cloud computing has enabled teams and organizations to streamline lengthy procurement processes. Cloud computing enables innovation by alleviating the need of innovators to find resources to develop, test, and make their innovations available to the user community. Innovators are free to focus on the innovation rather than the logistics of finding and managing resources that enable the innovation. Cloud computing is a powerful new abstraction for large scale data processing systems which is scalable, reliable and available.

Cloud computing definition

Cloud computing is a resource delivery and usage model, it means get resource (Hardware, software)via network. The network of providing resource is called ‘Cloud’. The hardware resource in the ‘Cloud’ seems scalable infinitely and can be used whenever.

Cloud computing and technology

New advances in processors, virtualization technology, distributed storage, broadband Internet access , automated management and fast, inexpensive servers have all combined to make cloud computing a compelling paradigm. This vast process power is usually got with a distributed, large-scale server cluster and server virtualization software.

What cloud computing means to service provider?

Fast Provision
Reduce servers scale
Increase resource utilization rate
Improve management efficiency
Lower maintenance cost
Location of infrastructure in areas with lower costs of real estate and electricity
Provide business continuity service
Improve management efficiency
Improve service levels
Complex architecture
Change of business model and faith

What cloud computing means to uSers?

Lower client workload
Lower Total Cost Ownership
Separation of infrastructure maintenance duties from domain-specific application development
Higher integratability
Not have to purchase assets for one-time or infrequent intensive computing tasks
Expand resource on-demand
Make the application have high availability
Quickly deploy application
Pay per use

Difficulties for cloud computing

Continuous high availability
Consistency
Interoperability and standardization
Scalability of all components
Data secrecy
Legal and political problem of data store and translation across regions
Performance issue
Difficulty customizing
Organizational obstacle

Architecture

Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud computing, comprises hardware and software designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services.
Cloud architecture extends to the client, where web browsers and/or software applications access cloud applications.
Cloud storage architecture is loosely coupled, where metadata operations are centralized enabling the data nodes to scale into the hundreds, each independently delivering data to applications or user.

How does this benefit the companies?

The companies don't have to buy a set of software or software licenses for every employee.
Instead, the company could pay a metered fee to a cloud computing company.
Cloud computing gives these companies the option of storing data on someone else's hardware, removing the need for physical space on the front end.

The benefits of cloud computing include that it can minimize:

infrastructure costs
save energy
reduce the necessity and frequency of upgrades
lessen maintenance costs
Cloud application services or "Software as a Service (SaaS)" deliver software as a service over the Internet
It eliminates the need to install and run the application on the customer's own computers and simplifying maintenance and support.
