Green Cloud Computing Essay

In his article “Online 24/7: ‘Life Logging’ Pioneer Clarifies the Future of Cloud Computing”, Larry Greenemeier (2011) describes the idea of cloud technology, where it stands today and where we are heading to. According to Greenemeier’s article, the idea of cloud computing is to make all the information and services available via web. It will enable access to data and apps without the need for a lot of storage or processing power on the devices themselves.

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

It is therefore a very exciting new paradigm which promises to offer many solutions to businesses which are willing to adopt it, at a very low cost. In the field of healthcare IT, the emergence of cloud based computation plays a major role in new opportunities and applications. There are many advantages of cloud such as the fact that the services are provided and managed by the cloud service provider. Therefore, the IT setup, maintenance and upgrade costs spiral down significantly for all the healthcare providers willing to adopt cloud based systems. Further, having a multi-tenant cloud based system instead of setting up IT infrastructure at every healthcare provider’s premises proves can be an energy conservation method which also drives down the operational costs significantly for healthcare providers. Further, most importantly, cloud works as a pay-as-you-use service wherein the cloud provider offers a vast array of services to his/her customer but the customer has the option to choose which services are needed and pay only for those. Therefore the customer can choose at any time to opt out of a service and pay only for the usage. Such a model is helpful because it helps share infrastructure and service.

Transform your business from traditional to environmentally friendly by utilizing cloud computing software. Many small to corporate size companies require the use of more servers to get jobs done because server utilization rates are about 5-10%, whereas cloud utilization rates are in the 70% range. Because cloud computing eliminates in-house servers, there isn’t the need for the constant climate control involved in maintaining servers—eliminating carbon footprints.

“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.

Cloud computing enables you to get to your information and projects outside of your own processing condition. Instead of putting away your information and programming on your PC or server, it is put away in 'the cloud'. This could incorporate applications, databases, email and record administrations.

Almost all modern day characteristics of cloud computing were thoroughly explored in Douglas Parkhill’s book, “The Challenge of the Computer Utility.” With global availability of high capacity networks, low cost computers and storage devices and the widespread adoption of hardware virtualization, service oriented architecture, autonomic, and utility computing have led to tremendous growth in cloud computing.

Internet has been developing very rapidly in wide range. It has become available and accessible for everyone. However, other issues such as storage size, the power consumed by equipment and hardware cost have been constantly increasing. The storage space in data center is no longer meeting our increasing demands. The innovation of cloud computing has emerged in an attempt to solve these and other environmental problems. This make software even more attractive as a service and shaping the way hardware is designed and purchased. According to Architectural requirements for cloud computing systems: An enterprise cloud approach, “The overarching goal of Cloud Computing is to provide on-demand computing services with high reliability, scalability, and availability in distributed environments. Despite this common goal, Cloud Computing has been described in many different ways and no standard definition has been adopted until now.”

The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

Cloud computing is an emerging paradigm that intends to provide on demand services through the internet (Chang & Tsai, 2008). In environmentally friendly power vitality perspective, the four aspects of cloud computing include low cost, large data storage, efficiency and reliability. Chang and Tsai (2008) incorporated the hadoop platform in cloud computing together with the access security under the influence of techniques such as finger print identification and face recognition. Most cell phones are served either through wired or through remote medium by hadoop cloud computing. Furthermore, most of slave nodes are controlled and connected by a master node which is located in the architecture defining Hadoop system where services such as PaaS, SaaS and IaaS are provided (Chang & Tsai, 2008).

According to a study, in the year of 2000, 45% of IT budget was spent on capital expenditure whereas only 6% of the resulting server capacity was utilized1. In this scenario, in the next couple of years the cost of server maintenance would exceed the capital expenditure invested with very less utilization ratio. Datacenters of large scales can reduce the economies and time of computing to a large extent and also contribute to the Green IT initiative saving the environment.

Abstract—Alongside the healthy development of the Cloud-based technologies across various application deployments, their associated energy consumptions incurred by the excess usage of ICT resources, is one of the serious concerns demanding effective solutions with immediate effect. Effective auto scaling of the Cloud resources in accordance to the incoming user demand and thereby reducing the idle resources is one optimum solution which not only reduces the excess energy consumptions but also helps maintaining

Second and the most important challenge faced by the companies are the amount of energy required to manage data centres. All the data centres around the world use around 30 billion watts of energy on average, which is equal to output by 30 nuclear power plants [6]. By 2020 it is expected that, US datacentres

First of all what is cloud computing? Cloud computing is the storing of data and applications on remote servers, and accessing them via the internet rather than saving or installing them on your personal or office computer. In order to understand cloud computing lets divide the cloud computing into two parts. The first part is computing whenever there is a computing there is one word that comes to our mind that is nothing but a computer. Computer computes something computed that computes something with the help of processor and memory so whenever there is a word computing then this consists of processor and memory. Then we move into the second part what is cloud? Cloud is a different name that has been used for internet. It is a different
