... will service individual homes and offices across the country.” This vision of computing utilities based on a service provisioning model anticipated the massive transformation of the entire computing industry in the 21st century whereby computing services will be readily available on demand, like other utility services available in today’s society. Similarly, users (consumers) need to pay providers only when they access the computing services. In addition, consumers no longer need to invest heavily or encounter difficulties in building and maintaining complex IT infrastructure. In such a model, users access services based on their requirements without regard to where the services are hosted. This model has been referred to as utility computing, or recently as Cloud computing . The latter term denotes the infrastructure as a “Cloud” from which businesses and users can access applications as services from anywhere in the world on demand. Hence, Cloud computing can be classified as a new paradigm for the dynamic provisioning of computing services supported by state-of-the-art data centers that usually employ Virtual Machine (VM) technologies for consolidation and environment isolation purposes . Many computing service providers including Google, Microsoft, Yahoo, and IBM are rapidly deploying data centers in various locations around the world to deliver Cloud computing services. Cloud computing delivers infrastructure, platform, and software (applications) as services, which...

...BENEFITS OF CLOUD COMPUTING TO BUSINESSES Cloud computing, the most buzzed word in this era offers benefits to all. For both small and large businesses as well cloud computing acts as an asset. It allows them to set up what is essentially a virtual office to give the business organizations the flexibility of connecting to their business anywhere, any time. According to a study conducted by the market research company Vanson Bourne, they found that there were numerous factors driving business organizations towards cloud adoption. The report summarized eleven drivers of cloud adoption along with quantifiable improvements these companies have achieved by deploying cloud services to improve productivity, lower cost, and improve time to market. The eleven drivers or the benefits of cloud computing to businesses are as follows: 1. Fresh Software- Immediate upgrades put new features and functionality into workers’ hands to make them more productive. Further, software enhancements are typically released quite frequently. This is in contrast to home grown or purchased software that might have major new releases only once a year or so and take significant time to roll out. 2. Do more with less-With cloud computing, companies can reduce the size of their own data centers — or eliminate their data center footprint altogether. The reduction of the numbers of servers, the software cost, and the number of staff can significantly reduce IT costs without impacting an organization’s IT capabilities...

...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...

...Balancing in Green Clouds Gaganjot Kaur* *M.Tech,IITT College of Engineering & Technology, Pojewal, Punjab Abstract — Cloud Computing can be defined as dynamically scalable shared resources that are completely accessed over a network and the users have to only pay for what they use and can share internally or with other customers as well. The majority of cloud computing infrastructure currently consists of reliable services delivered through data centers that are built on computer and storage virtualization technologies. The goal of a cloud-based architecture is to provide some form of elasticity, the ability to expand and contract capacity on-demand. The implication is that at some point additional instances of an application will be needed in order for the architecture to scale and meet demand. That means there needs to be some mechanism in place to balance requests between two or more instances of that application. The mechanism most likely to be successful in performing such a task is a load balancer. The aim of this paper is to discuss the existing techniques of load balancing and elaborate the main points of the techniques that are helpful in reduction of power consumption leading a step towards green clouds. Green Cloud is an Internet Data Center architecture which aims to reduce data center power consumption, and at the same time guarantee the performance from users’ perspective, leveraging live virtual machine migration technology.
