Cloud Computing Essay

Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of

“Cloud Computing” is a buzzword that the IT industry has been talking about since the past few years. The future of computing is distributed and off-premise where remote servers handle terabytes of data every day. From both technical and social viewpoint, the concept of distributed data centers maintained by “server” companies somewhat dates back to 1990s where grid computing was actively thought upon as an IT requirement. Cloud Computing’s primary aim is provision of IT as-a-service to the cloud users on a utility-based delivery model envisioning greater storage availability, flexibility and scalability of IT systems.

Abstract-The excessive demand of pay per usage Cloud Computing model, considerably raise the need to balance the load in datacenter. Load balancing guarantees the availability of services without degrading the performance to users. Downtime observed by users is a big issue which leads to violation of quality of services (QoS) and requirements for users in time. Solution to this problem lies in improvement of response time.

The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles Cloud computing is so named because the information being accessed is found in the "clouds", and does not require a user to be in a specific place to gain access to it. The services are offered from data centres all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" is to simplify the huge network connections and computer systems involved in online services. Cloud computing is a computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centres are made available to IT and end users. Cloud computing is a type of computing that is comparable to grid computing. It relies on sharing computing resources rather than having local servers or personal devices to handle applications.

Cloud computing provides computing architecture, which is dynamic in nature and can evaluate performance behavior as well as other infrastructure challenges. This paper focuses on workload balancing workload balancing of cloud instances and also tells about the tools that evaluate performances. It tells that their proposed mechanism schedules the starting and shutting down of the VM instances automatically and allows the cloud instances to finish the assigned jobs within the deadline and within the price range.

Cloud computing has become a compelling paradigm for delivering and managing services over the internet. Although it might be difficult to define cloud computing, one simple definition of the term is virtualized third-party hosting. In simple terms, instead of renting the entire or actual physical server, one rents a certain proportion of server resources. The client’s server runs within a virtual container that may be moved from a physical server to another without service interruption. Cloud computing has changed the entire landscape of Information Technology, and it is finally actualizing the long-standing promise of utility computing. This paper serves as a comprehensive overview of the cloud computing technology; definition,

While there are many definitions of cloud computing which often depends on the cloud user, NIST (National Institute of Standards and Technology) has unified the definition of cloud computing based on five characteristics that distinguish cloud computing to on premise computing environment - on-demand self-service, broad network access, resource pooling, rapid elasticity

Cloud computing is real time computing services that are delivered over the Internet. Such services include servers, storage, databases, networking, software, and more (Microsoft Azure). Cloud computing is offered by service providers that typically charge a pay per use fee for service usage. Cloud computing is heavily integrated into daily technology use from email clients to collaborative text editing software such as Google Docs. Cloud computing can virtualize an IT system or essentially turn software virtualized and real time.

Cloud computing is one of the most useful technology that is been widely used all over the world. It generally provides on demand IT services and

Cloud computing is a way of providing IT enabled capabilities as reliable service-on-demand with elasticity and scalability, where users can make use of infrastructure, resources, platform, or software without manual intervention and manage the fundamental complexity of the

Cloud Computing is the newly growing branch of Software World which has its impact on several fields.Cloud Computing is nothing but a distributed computing on internet which provides utilization of computing resources on remote server instead of occupying them on local machine.Cloud Computing has made things easy.Cloud Computing principles are the building blocks of it.Without this principles one cannot fully utilize resources.In this paper we have highlighted the principles of cloud computing.One should be aware of this principles.

ABSTRACT: The operating cost of the data centers can be decreased by reducing the energy consumption. By implementing various allocation policies of virtual machine allocation in cloud computing the total energy consumption can be reduced up to 14% and total monetary energy costs can be lowered by up to 26%.

Abstract: Load balancing is essential for optimization of resources in distributed environments. The major goal of the cloud computing service providers is to use cloud computing resources efficiently to enhance the overall performance. Load balancing in cloud computing environment is a methodology to distribute workload across multiple computers to achieve optimal resource utilization with minimum response time. The proposed system pave the way for the green

Cloud Computing is the use of common software, functionality or business applications from a remote server that is accessed via the Internet. Basically, the Internet is the "cloud" of applications and services that are available for access by subscribers utilizing a modem from their computer. With Cloud Computing, one simply logs into desired computer applications - such as sales force or office automation programs, web services, data storage services, spam filtering, or even blog sites. Generally, access to such programs is by monthly or annual paid subscription. Through Cloud Computing, businesses may prevent financial waste, better track

A simple architecture of cloud computing consist the data centers servers for web application as well as a switch whose function is balancing the load and distribute the load to set of application server also hav-ing set of backend storage server. Fig. 1 shows the typical architecture of data center server for the In-ternet applications. It consists of a load balancing switch, a set of application servers, and a set of backend storage servers. The front end switch is typically a Layer 7 switch [5] which parses application level informa-tion in Web requests and forwards them to the servers with the corresponding applications running.
