Improvements Of The Energy Efficiency For Cloud Computing

Cloud computing is on the rise. Cloud computing is a style of computing where software and virtualized hardware is provided over the internet (O’Brien & Marakas, 2011). The seven most common uses of cloud computing include: infrastructure as a service, private cloud or hybrid cloud, test and deployment, big data analytics, file storage, disaster recovery and backup (Ferkoun, 2014). The biggest advantages of cloud computing include increasing competitiveness through cost reduction, greater flexibility, and elasticity and optimal resource utilization (Ferkoun, 2014). Cloud computing basically uses the internet to provide for the computing needs of the end users.

The questions in this exercise can be answered by doing internet search and/orfrom the YouTube videos. Answer to each question should be one paragraph in your own words.

Modern data centers and hardware that focus on energy efficiency, high availability, security and scalability to provide a physical infrastructure for our new IT vision to grow

Cloud computing can be understood as a multifaceted infrastructure of hardware, software, storage and processing available to be used as a service. With the use of cloud computing, without even knowing how it works, one can access a large number of the most sophisticated supercomputers of the world and their respective processing powers without being overwhelmed with space or information. Cloud computing allows access to computer networks located at various places in the world and thus offers the speed of

Cloud computing is a “newsworthy” term in the IT industry in recent times and it is here to stay! Cloud computing is not a technology, or even a set of technologies – it’s an idea. Cloud computing is not a standard defined by any standards organization. Basic understanding for Cloud: “Cloud” represents the Internet; Instead of using applications installed on your computer or saving data to your hard drive, you’re working and storing stuff on the Web. Data is kept on servers and used by the service you’re using; tasks are performed in your browser using an interface/ console provided by the service. A credit card and internet access is all you need to make an investment in

“Cloud” computing is the fanciest buzzword in the computer industry, currently surpassing the last big term “web 2.0”. Every big player in the computer industry launched a cloud service last year. Notable examples are iCloud by Apple, (Apple 2012) or Microsoft Cloud Services (Microsoft 2011), copying various innovators like Google or Dropbox, who offer similar services since much longer. The latter is the most successful

The world is turning to cloud computing to manage data. Businesses are at the forefront of this new trend with companies such as Google, Amazon, Microsoft, and others leading the way by providing these services. What exactly is cloud computing? According to Turban & Volonino (2011), cloud computing is Internet- based computing in which shared resources (such as hard drives for storage) and software apps are provided to computers and other devices on- demand (p. 48).

As we all likely already know, there 's a LOT of hype associated with cloud computing. Cloud computing is a huge topic. It encompasses diverse models and technologies, even though

Cloud computing can be viewed as one of the most rapidly growing and evolving paradigm.Webmail,online storage and online documents are most famous examples in which customers can access their data via web browsers on the internet. The original idea of the cloud computing was delivered by J.C.R Licklider in sixties (Mohamed 2009). Cloud computing has developed since then and started to server the publics after internet offered a significant bandwidth in the nineties (Mohamed 2009). Cloud computing has been through many different phases and is still rapidly evolving.

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.

Abstract – Cloud computing is a type of computing that relies on sharing a pool of physical and/or virtual resources (e.g., networks, servers, storage, applications and services), rather than deploying local or personal hardware and software. This technology is mainly service oriented and focuses on cost reduction, hardware reduction and pay just for service concept. Virtualization in cloud computing is making a virtual image of the storage devices servers or network resources so that they can be used on multiple machines at the same time.

Cloud Computing appears as a computational paradigm as well as distribution architecture and its main objective is to Provide secure, quick, convenient data storage and net computing device, with all computing resource visu-alized as service ,with all computing resources visualized as service and delivery over the internet [1,2].The cloud enhances collaboration, agility, scalability, availability, ability to adapt to fluctuations according to demand, accelerate development work, and provides potential for cost reduction through optimized and efficient compu-ting [3,5].Cloud computing is buzz word of IT industry today and present everywhere and every one's mind. Cloud computing is ubiquitous, next generation's infor-mation technology architecture which offers on-demand access to the network. It is dynamic, virtualized, scalable and pay per use model over internet. Cloud computing is a box of several concepts such as virtualization, Service oriented architecture (SOA), web 2.0 and many more. In some respects, Cloud Computing represents the maturing of these technologies and is a marketing term to repre-sent that maturity and the services they provide [4].There are several advantages of adopting cloud computing but still journey of cloud is not easy. Cloud still is its early stage, suffering from many pitfalls and one of the most concern is security along with availability, privacy and compliance. Traditional security mechanism such as Authentication , authorization ,

With the growing of technology and people around the world using the internet more often, the cloud is becoming more popular than ever before. The United States National Institute of Standards and Technology has defined cloud computing as follows: "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 [1]." There are many uses of the cloud but the main uses people use the cloud for is to host websites, store documents, and to stream TV shows and movies. With all this new flooding of the cloud computing network, the dependability of cloud computing systems have come into question for all cloud service providers, consumers, and brokers around the world. Fig. 1 is just one example of the growth of cloud computing of a single company.

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 have revolutionized life as we know it; it allows people to store, manage, and access their data by using a network of remote servers which are hosted on the internet rather than using a local server or own hardware. A recent study conducted by KPMG found that 81% of businesses were either evaluating cloud services, planned a cloud implementation or had already implemented a cloud strategy [1]. Organizations tend to use the cloud to reduce costs and improve efficiency. Cloud is not a commodity, some people think that it comes out of the sky, while in fact it comes from physical hardware inside brick and mortar facilities which are connected to hundreds of miles by networking cables.
