The Cloud Computing For Pc Management

Published Date: 02 Nov 2017

In this work i will consider the problem of using cloud computing for personal computer management.Cloud computing is really a doorway of new kind of com�puting concept.we all know that cloud computing brings a new way of cost ef�fecting data management and access of data into the system. so there is a big chance that we could use this advantage to a grater bene.t.I am thinking about a new system that can work in mobile device such a mobile smartphone and tabloid device. With the help of Cloud computing and Integrated memory com�puting we can be able to access the whole personal computer interface in mobile with our smartphone or tabloid device.The reason we need this technology is that we are not able to carry a computer to everywhere anytime,but we could use the help of those powerful computer anywhere.And The recent teleology is so unstable that most of the computer became obsolete within few years.so if we can share computing power from a cloud server,maybe we could prevent waste of those valuable technology resources.

Now is time to talk about the problem that we could face and the necessary technology we are going to use.well, we already have everything we need to build a system we want.But for this kind of system will need lots of internet band�width and a very costly cloud server.My approach extends techniques previously used in the context of other program analysis problems and also new ideas and technology.

The cloud technology a new era of computing where application services are provided through the Internet from a duplicated server called cloud. Cloud com�puting can also enhance the computing capability of mobile systems, and is it the ultimate solution for extending such systems� battery lifetimes ? Analysis in�dicates that the energy saved by computation o.oading depends on the wireless bandwidth B, the amount of computation to be performed C, and the amount of data to be transmitted D. Existing studies thus focus on determining whether to o.oad computation by predicting the relationships among these three factors[1].

There is no doubt that software as a service (SaaS) and the more general in�frastructure technology that facilitates this type of software delivery and pricing-Cloud Computing are becoming new platforms for personal computing.They compete with traditional desktop or hand held computers including smartphones that run application directly on the devices. we can see all the platform concept direct and indirect network e.ect at ecosystem level as well as .rms o.ering infrastructure in addition to product,open versus closed system,and con.icts of interest emerging between platform leaders and their complementers[2].

Cloud computing is a way to increase the capacity or add capabilities dy�namically without investing in new infrastructure, training new personnel, or licensing new software. It extends Information Technology�s (IT) existing capa�bilities. In the last few years, cloud computing has grown from being a promising business concept to one of the fast growing segments of the IT industry. But as more and more information on individuals and companies are placed in the cloud, concerns are beginning to grow about just how safe an environment it is. Despite of all the hype surrounding the cloud, enterprise customers are still reluctant to deploy their business in the cloud. Security is one of the major issues which re�duces the growth of cloud computing and complications with data privacy and data protection continue to plague the market. The advent of an advanced model should not negotiate with the required functionalities and capabilities present in the current model. A new model targeting at improving features of an existing model must not risk or threaten other important features of the current model. The architecture of cloud poses such a threat to the security of the existing technologies when deployed in a cloud environment. Cloud service users need to be vigilant in understanding the risks of data breaches in this new environment. In this paper, a survey of the di.erent security risks that pose a threat to the cloud is presented. This paper is a survey more speci.c to the di.erent security issues that has emanated due to the nature of the service delivery models of a cloud computing system[3].

With cloud computing, the software programs you use arent run from your personal computer, but are rather stored on servers accessed via the Internet. If your computer crashes, the software is still available for others to use. Same goes for the documents you create; theyre stored on a collection of servers accessed via the Internet. Anyone with permission can not only access the documents, but can also edit and collaborate on those documents in real time. Unlike traditional computing, this cloud computing model isnt PC-centric, its document-centric. Which PC you use to access a document simply isnt important[4].

Large new cloud service such as Microsoft�s windows Intune platform enable customers to create and run their own service in Microsoft data centers,windows Intune to manage and secure PCs or Dallas to create a cloud based marketplace for data[5].

3 De.ning Cloud Computing

Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the common use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing en�trusts remote services with a user�s data, software and computation. End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user�s data are stored on servers at a remote location. Proponents claim that cloud computing allows companies to avoid upfront infrastructure costs, and focus on projects that di.erentiate their businesses instead of infrastructure. Proponents also claim that cloud com�puting allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet .uctuating and unpredictable business demand.

3.1 Main Bene.ts of Cloud Computing

1.Cost :The infrastructure is typically provided by a third-party and does not need to be purchased for one-time or infrequent intensive computing tasks.So the cost will be low.

2.Agility: improves with users� ability to re-provision technological infras�tructure resources.

3.Reliability: is improved if multiple redundant sites are used, which makes well-designed cloud computing suitable for business continuity and disaster re�covery.

4.Performance: is monitored, and consistent and loosely coupled architec�tures are constructed using web services as the system interface.

5.Security: could improve due to centralization of data, increased security-focused resources, etc., but concerns can persist about loss of control over certain sensitive data, and the lack of security for stored kernels.[34] Security is often as good as or better than other traditional systems, in part because providers are able to devote resources to solving security issues that many customers cannot a.ord. However, the complexity of security is greatly increased when data is distributed over a wider area or greater number of devices and in multi-tenant systems that are being shared by unrelated users. In addition, user access to security audit logs may be di.cult or impossible. Private cloud installations are in part motivated by users� desire to retain control over the infrastructure and avoid losing control of information security.

6.Maintenance : Maintenance of cloud computing applications is easier, because they do not need to be installed on each user�s computer and can be accessed from di.erent places.

4 Cloud Computing Service Model

Software as a Service(SaaS): This is typically end user applications delivered on demand over a network on a pay per use basis. The software requires no client installation, just a browser and network connectivity. An example of SaaS is Mi�croSoft O.ce365. Until its launch, if a user required say Word, they would have to purchase it, install it, backup .les etc. With O.ce365 Word can be acquired for a small monthly fee, with no client installation, the .les are automatically backed up, software upgrades are automatically received and the software can be accessed from anywhere. Decide you do not require Word anymore stop paying the monthly fee. It is that simple.

Platform as a Service(Paas): Used by software development companies to run their software products. Software products need physical servers to run on, with database software, often Web servers too. These are all the platform that the application runs on. Building this yourself is a time consuming task and needs to be continually monitored and updated. PaaS provides all of the platform out of the box enabling software applications to be given to the platform which will execute them with no requirement for administration of the lower level components.

InfraStructure as a Service(Iaas): This covers a wide range of features, from individual servers, to private networks, disk drives, various long term stor�age devices as well as email servers, domain name servers as well as messaging systems. All of these can be provisioned on demand and often include soft�ware license fees for operating systems and associated software installed on the servers. Organisations can build a complete computing infrastructure using IaaS on demand.

Network as a service (NaaS):In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. Cloud users do not manage the cloud infrastructure and plat�form where the application runs. This eliminates the need to install and run the application on the cloud user�s own computers, which simpli.es maintenance and support. Cloud applications are di.erent from other applications in their scalabilitywhich can be achieved by cloning tasks onto multiple virtual machines at run-time to meet changing work demand.Load balancers distribute the work over the set of virtual machines. This process is transparent to the cloud user, who sees only a single access point. To accommodate a large number of cloud users, cloud applications can be multitenant, that is, any machine serves more than one cloud user organization. It is common to refer to special types of cloud based application software with a similar naming convention: desktop as a ser�vice, business process as a service, test environment as a service, communication as a service.

5 Cloud Computing For PC Management

The modern computer houses an incredibly powerful processor that enables it to make millions of calculations per second. Given the growing speed of internet connections, many see few reasons that computation can�t be done on a cloud system, with the resulting data wired back to the .rst machine. This sort of system would e.ectively replace high-power computer chips with lower-power interpretation devices. Instead of crunching the numbers,our computer would turn to a cloud server, send it the things it needs calculated, and await the answers. The internet connection can replace the RAM, CPU, massive hard drive, and graphics card on our system.A great deal of energy goes into the manufacturing and operation of those components. Our computer tower is home to all of these components and little else. If we remove the RAM and CPU, we essentially eliminate the need for high throughput cooling fans. This is even more true if we remove your graphics processor. The CPU and GPU consume the most electricity. Removing them nearly eliminates the demand for a bulky power supply. At the end of all this, we�ll .nd we have a monitor, a minimal processor, an incredibly high speed internet connection, and perhaps some form of limited local storage.

There are a few technical barriers to be overcome before there will be widespread, in-home adoption of cloud computing. Commercial and corporate growth is something entirely di.erent -there are fewer migration problems because most corporations already have robust networks with IT departments capable of man�aging the process. Their general usage is also di.erent. Here are some of the barriers to residential cloud computing -and some of the reasons there has yet to be a �cloud computer� to hit the market:

1.High speed internet isn�t available everywhere: It�s an absolute requirement for full cloud integration.

2.Internet speed or Bandwidth: We�re nearing the point that high definition video can be streamed without much trouble. However, the video requirements of most computer games, a huge part of residential computing, run poorly when processed over networks.

3.Overall faith in the system is low: People are very hesitant to rely solely on something as intangible as the cloud.

4.Competition: This may seem silly, but the lack of a unified cloud service makes people weary of depending on one company or another. Complete integration would make the choice of cloud provider very important.

5.Necessity and cost: The average computer user won�t see the benefit of learning to use cloud systems until the cost drops below the entry price for a traditional computer.

The industry is moving away from robust desktop o.erings unless they�re catered to games. The Smartphone movement has shown how popular low-power, portable devices can be. Modern laptops are moving away from bulky and powerful, becoming ever slimmer and ever more e.cient.

6 Current Available Cloud services

eyeOS: Its Mainly a cloud computing concept that seeks to enable collabora�tion and communication among users. It is mainly written in PHP, XML, and JavaScript. It is a private-cloud application platform with a web-based desktop interface. Commonly called a cloud desktop because of its unique user interface, eyeOS delivers a whole desktop from the cloud with .le management, personal management information tools, collaborative tools and with the integration of the clients applications.

Jump Desktop : Is a remote desktop app which allow us to connect and control any computer of the world.

Glide OS : Glide OS is a cross-platform web desktop developed by TransMe�dia Corporation. It is notable for operating on both desktop operating systems, like Microsoft Windows, Mac OS X and Linux and mobile operating systems like Apple iOS, Google Android and Honeycomb, BlackBerry OS and Black-Berry Tablet OS (QNX), webOS, Symbian and Windows Mobile. Glide OS is compatible with a variety of web browsers, including Microsoft Internet Explorer, Mozilla Firefox, Apple Safari, and Google Chrome.

YouOS replicated the desktop environment of a modern operating system on a webpage, using JavaScript to communicate with the remote server. This allows users to save the current desk�top state to return to later, much like the hibernation feature in many true operating systems, and for multiple users to collaborate using a single environ�ment. YouOS featured built-in sharing of music, documents and other .les. The software was in alpha stage, and was referred to as a �web operating system� by WebShaka.

6.1 Cloud Web Services

The new generation computing system called cloud computing is a totally inter�net based technology.World�s top online web service Providers such as Amazon, Google, Salesforce, IBM, Microsoft, and Sun Microsystems have begun to establish new data centers for hosting Cloud computing application services such as social networking and gaming portals, business applications (e.g., Sales�Force.com), media content delivery, and scienti.c workfolk.But actual services vary with the need of the provider and user requirement.

7 Conclusion

What does the future hold? We will hazard a few predictions,based on our beliefs that the economics of computing will look more and more like those of energy. Neither the energy nor the computing grids of tomorrow will look like yesterdays electric power grid. Both will move towards a mix of micro-production and large utilities, with increasing numbers of small-scale producers (wind, solar, biomass, etc., for energy;for computing, local clusters and embedded processorsin shoes and walls) co-existing with large-scale regional producers, and load being dis�tributed among them dynamically. Yes, computing isnt really like electricity, but we do believe that we will nevertheless see parallel evolution, driven by similar forces.

Development of fundamental techniques and software systems that integrate distributed clouds in a federated fashion is critical to enabling composition and deployment of elastic application services. We believe that outcomes of this re�search vision will make signi.cant scienti.c advancement in understanding the theoretical and practical problems of engineering services for federated environ�ments of cloud computing in mass level.
