...Mobile Cloud Computing (MCC): A Survey Abstract: Mobile devices have come a long way and their capabilities in terms of speed, raw computing capabilities, storage capacity and the applications that are real world end user friendly. The sale of mobile devices has seen a huge boom and is now surpassing those of PCs [1]. With this enormous use of smart phones across the world and as well as the introduction of cloud computing concept, Mobile Cloud computing or MCC has become the new paradigm in the world of mobile services. This paper will discuss the technology of MCC, applications and challenges faced. Mobile Cloud Computing: Introduction MCC in its simplest form can be defined as an infrastructure where the storage of data and its processing is outside a mobile device. What mobile cloud computing does is move processing and storage to the cloud and thereby bringing applications and the computing power to a broader spectrum of mobile users [2]. Mobile service providers can provide services to the subscribers as AAA which refers to authentication, authorization and as well as accounting which is based on what is known as an home agent or HA and the end users data being stored on the cloud database. Every time a request is initiated from the subscriber, it is delivered to the cloud based system with the help of Internet. The controllers on the cloud will be able to process these requests and eventually providing the subscribers with the respective cloud based service. These...

...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 use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. There are many types of public cloud computing:[1] Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS) Storage as a service (STaaS) Security as a service (SECaaS) Data as a service (DaaS) Database as a service (DBaaS) Test environment as a service (TEaaS) Desktop virtualization API as a service (APIaaS) Backend as a service (BaaS) In the business model using software as a service, users are provided access to application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run. SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis. Saas providers generally price applications using a subscription fee. Proponents claim that the SaaS allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. This will enable a business to reallocate IT operations to focus on other IT goals. In addition, the application is hosted centrally, so updates can be released without users...

...more and more tasks, e.g., for playing games; capturing, editing, annotating and uploading video; handling finances; managing personal health, micro payments, ticket purchase, interacting with ubiquitous computing infrastructures. Even mobile device hardware and mobile networks continue to evolve and to improve, mobile devices will always be resource-poor, less secure, with unstable connectivity, and with less energy since they are powered by battery. Mobile devices can be seen as entry points and interface of cloud online services. Mobile devices (e.g., smartphone, tablet pcs, etc.) are increasingly becoming an essential part of human life as the most effective and convenient communication tools not bounded by time and place. Mobile users accumulate rich experience of various services from mobile applications (e.g., iPhone apps, Google apps, etc.), which run on the devices and/or on remote servers via wireless networks. The rapid progress of mobile computing (MC) becomes a powerful trend in the development of IT technology as well as commerce and industry fields. However, with mobility come its inherent problems such as resource scarceness, finite energy and low connectivity. Real time applications demand high levels of responsiveness, which in turn, demand intensive computing resources. Some mobile applications, such as location based social networking, process and make use of the phone’s various sensor data which is expensive in...

...Cloud computing A collection of working papers Thomas B Winans John Seely Brown Cloud Computing frequently is taken to be a term that simply renames common technologies and techniques that we have come to know in IT. It may be interpreted to mean data center hosting and then subsequently dismissed without catching the improvements to hosting called utility computing that permit near realtime, policy-based control of computing resources. Or it may be interpreted to mean only data center hosting rather than understood to be the significant shift in Internet application architecture that it is. Perhaps it is the name. Certainly it is more nebulous than mnemonic, if you’ll pardon the poor pun. We happen to think so too. We’d rather use the term service grid, frankly, but that name also has its problems. The fact is that cloud and service grid computing are paradigmatically different from their common interpretations, and their use can shed light on how internet architectures are constructed and managed. Cloud computing represents a different way to architect and remotely manage computing resources. One has only to establish an account with Microsoft or Amazon or Google to begin building and deploying application systems into a cloud. These systems can be, but certainly are not restricted to being, simplistic. They can be web applications that require only http services. They might require a relational database. They might require web service infrastructure and message queues...

...science-cloud computing [pic] cloud computing 2012-cloud computing cloud computing-year-2011 cloud computing-2 best-papers-EEE cloud computing data storage in cloud computing data-compression-in-cloud-computing Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallels to this concept can be drawn with the electricity grid, where end-users consume power without needing to understand the component devices or infrastructure required to provide the service. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualized resources It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet. This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if they were programs installed locally on their own computers.[5] Typical cloud computing providers...

... Cloud computing is the latest evolution of Internet-Based Computing. Public internet spawned private corporate intranets, cloud computing is now spawning private cloud platforms. The database is the critical part of that platform. Therefore it is imperative that our cloud database be compatible with cloud computing. Key Design principles of the cloud model: The core design principle is dynamic scalability, or the ability to provision and decommission servers on demand. The shared-disk database architecture is ideally suited to cloud computing. It requires fewer and lower cost servers, it provides high availability, reduces maintenance costs by eliminating partitioning and it delivers dynamic scalability. Benefits of Cloud Computing: a. Lower Costs: All resources are shared resulting in reduced costs. b. Shifting CapEx to OpEx: This enables customer to focus on adding value in their areas of competence. It allows customer to focus their money and resources on innovating. c. Agility d. Dynamic Scalability: It can smoothly and efficiently scale to the spikes with a more cost-effective pay-as-you-go model. e. Simplified maintenance: All Patches and upgrades are deployed across the shared infrastructure. f. Large scale prototyping/load testing g. Diverse platform support h. Faster Management approval i. Faster development With corporate adoption of cloud computing there are explosion of cloud options....

...search for keywords in the encrypted data and use the encrypted data as an input to computation or comparison operations. Because decrypting data stored at the cloud servers may possibly expose its content to the provider servers at least, so it is advised that it is more secure to decrypt data only on trusted machines which are controlled by the user who is authorized to access the data. Figure 2.2 Basic Architecture for Preserving Data Privacy in the Cloud Figure 2.2 shows the basic architecture of encryption for privacy protection before sending it to the cloud server. The data remain encrypted in the cloud server and only authorized users can get the credential for accessing this encrypted data. The encrypted data can be decrypted only after the data are downloaded to an authorized user device or machine. In such scenario, the privacy of the data doesn’t depend on any implicit assumption of trust of the server or the service level of agreement (SLA). Instead, the protection of privacy or integrity completely depends on the encryption techniques used to protect the data [45ECC]. The other leftover issues are how to allow the authorized users and data owner to search...

...CLOUD COMPUTING: PAST, PRESENT, AND FUTURE John P. Sahlin (sahlinj@gwu.edu) The George Washington University, United States of America ABSTRACT Defining cloud computing can be difficult, as each organization often has its own spin on the definition. Despite being hard to define, Gartner Research named cloud computing as one of the top technologies to watch in 2010, 2011, and 2012. At its core, cloud computing is a technical architecture that meets a specific business need. This chapter traces the roots of cloud computing from its origins in mainframe distributed computing, discusses the basics of the cloud computing model today, and offers insights for future directions that are likely to be pursued in the cloud computing arena. A number of challenges to cloud computing are identified, including concerns of security and how to deal with the rise of mobile computing. The chapter ends with recommendations on how to choose which cloud model is most appropriate to meet your organization’s needs and how to establish a successful cloud strategy. INTRODUCTION: DEFINING THE CLOUD I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it. ~ Hon. Potter Stewart (U.S. Supreme Court Justice) Why did Gartner Research place cloud computing at the top of the list of most important technology focus areas for the past three years...

...CLOUD COMPUTING: Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services -- such as servers, storage and applications -- are delivered to an organization's computers and devices through the Internet. Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine. HOW CLOUD COMPUTING WORKS: The goal of cloud computing is to apply traditional supercomputing, or high-performance computing power, normally used by military and research facilities, to perform tens of trillions of computations per second, in consumer-oriented applications such as financial portfolios, to deliver personalized information, to provide data storage or to power large, immersive computer games. To do this, cloud computing uses networks of large groups of servers typically running low-cost consumer PC technology with specialized connections to spread data-processing chores across them. This shared IT infrastructure contains large pools of systems that are linked together,Often, virtualization techniques are used...

...What is Cloud? The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something which is present at remote location. Cloud can provide services over network i.e. on public networks or on private networks i.e. WAN, LAN or VPN. Applications such as e-mail, web conferencing, customer relationship management (CRM), all run in cloud. What is Cloud Computing? Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure and application. We need not to install a piece of software on our local PC and this is how, the cloud computing overcomes platform dependency issues. Hence, the Cloud Computing is making our business application mobile and collaborative. Cloud Computing Technologies There are certain technologies that are working behind the cloud computing platforms making cloud computing flexible, reliable, usable. These technologies are listed below: * Virtualization * Service-Oriented Architecture (SOA) * Grid Computing * Utility Computing Virtualization Virtualization is a technique which allows to share single physical instance of an application or resource among multiple organizations or tenants(customers). It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded. The Multitenant architecture offers virtual isolation among the multiple tenants and therefore, the organizations...

...Cloud Computing ABSTRACT Cloud computing is Internet- ("cloud-") based development and use of computer technology ("computing"). In concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. Cloud computing describes a new supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. The term cloud is used as a metaphor for the Internet, based on the cloud drawing used to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online which are accessed from a web browser, while the software and data are stored on servers. These applications are broadly divided into the following categories: Software as a Service (SaaS), Utility Computing, Web Services, Platform as a Service (PaaS), Managed Service Providers (MSP), Service Commerce, and Internet Integration. The name cloud computing was inspired by the cloud symbol that is often used to represent the Internet in flow charts and diagrams. THE CLOUD COMPUTING AN INTRODUCTION: ...
