CHAPTER 1 : INTRODUCTION

Mobile devices allow users to run powerful applications that take advantage of the growing availability of built-in sensing and better data exchange capabilities of mobile devices. As a result, mobile applications seamlessly integrate with real-time data streams and Web 2.0 applications, such as mashups, open collaboration, social networking and mobile commerce. The mobile execution platform is being used for 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

...Introduction What is cloud computing? To explain, it is kind of hard to explain as it is more like technology thing which only IT peoples know well. Assume you have run a big corporation; your responsibility is to make sure your employees have the right hardware and software to do their job. But, purchasing computer is not enough as you need to purchase software license give employees the right tools. This will cost a lot and eventually lost profit. Instead for each computer install the software, you just have to load one application only. That application would allow employees to access to the server and do the works. And using remote machines would run everything like email to complex data analysis programs (Strickland, 2008). That is cloud computing. As the one of a team which recently graduated software engineers working on a project to recommend an operating system choosing from either Ubuntu or Windows that able to leverage cloud computing enabling faultless access to the organization data and with services, applications and features that are vibrant and updatable immediately.

...Cloud Computing Introduction This term paper will describe the characteristics of Cloud Computing and services associated with it. It will cover how businesses deploy services such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), as well as some of the benefits and challenges of Cloud Computing. Cloud Computing Definition - Cloud Computing is basically servers providing specific services to businesses and individuals over the internet. Characteristics * Shared Infrastructure — is when data centers use virtualization software on existing servers. This cuts down on total cost of infrastructure, storage, and networking bandwidth. * Dynamic Provisioning —Server computing instances or virtual machines are provisioned dynamically from a centralized console using automated software. The amount of services provided are determined by current demand requirements. * Network Access — One thing I like about Cloud Computing is the ability to access your account from anywhere, from any device. As long as you have an internet connection, you can use your pc, tablet, laptop, or mobile devices. An example is using iCloud storage to backup and restore your iphone. * Managed Metering — Another thing I like about Cloud Computing is you are only billed for what you use.

...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...

...The power of cloud You can hardly look at an IT strategy document today without seeing mention of cloud computing, even though it has been around for years. This model has now crossed the chasm to penetrate corporate America, which traditionally relied on internal infrastructure. This is a significant shift in IT mindset in what will certainly be remembered as a disruptive technology strategy that changed the way the world works, literally. What is cloud? Cloud computing is a pay-per-use consumption and delivery model that enables real-time delivery of configurable computing resources (for example, networks, servers, storage, applications, services). Typically, these are highly scalable resources delivered over the Internet to multiple companies, which pay only for what they use. Cloud delivery models can help organizations scale their investments as they grow their business. They can also open the door to new business approaches through standardized applications, infrastructure, testing environments and business processes that help improve service delivery and efficiency.
