The Cloud Of Cloud Computing

Cloud computing is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure. [1] Example: Google application engine, Software as a Service (SaaS) is

Cloud computing is unlike traditional hosting alternatives that use a single dedicated server, as cloud computing uses virtualization technology to pool or share resources from an underlying network of physical servers. In other words, a group of physical servers acts like one big server to bring you the resources that you need on demand. Cloud computing delivers shared computing resources, data or software through the Internet; which is the most common way of accessing the cloud. However, intranets and dedicated networks are also used too. Resources provided by the cloud include: networks, servers, storage, platforms, applications and other services. And these resources are shared between people and organizations, and accessed by applications or users.

Cloud computing refers to an internet based computing technology where shared servers provide infrastructure, software and various other resource to customers on a “pay-as-use” basis. Cloud users need not know how the resources are managed. Hence they can concentrate on the business functionality of the service rather than the underlying functionality involved in the management of the resources. These customers do not own the physical infrastructure, but rent these resources from a third-party agency. This concept is widely utilised by the industry, government and in the educational sector due to the ability to provide robust, resilient and scalable computing power. The resources are provisioned to the user based on determining the required computing resources by the customer.

This report will be exploring what cloud computing is, the usages of cloud computing, a comparison of organisations that offer cloud services and their architectures, an explanation on how a typical software company may benefit from having a cloud implementation, a description of a challenge that cloud computing has in research and a description of a challenge in a commercial adaptation in connection to cloud computing.

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.

So, what is actually cloud computing and how does it work? “Cloud computing refers to a model of computing that provides access to a shared pool of computing resources (computers, storage, applications, and services), over a network, often the Internet. These “clouds” of computing resources can be accessed on an as-needed basis from any connected device and location” (Kenneth 2012). So basically cloud computing connects one device to another device through the Internet, and it could share virtually any type of file from one device to another. There are three main types of cloud services: public, private and hybrid. All three services addresses different requirement and concerns, and they have their own advantages and disadvantages.

Today, the cloud computing Service business sector is genuinely soaked, offering organisations and customers an extensive variety of services to pick between. So, choosing the right cloud services to trust with your essential applications, sensitive information, and to build successful system will be hard. Mostly small organisations and new organisations can think that it’s nearly difficult to make up minds for Cloud technology as many don 't know how to pick the right Cloud Service supplier. Here are few elements to consider to separate the right Cloud service supplier from others.

Cloud computing is a topic of which much is assumed. The average person recognizes the term “cloud computing” as having to do with their storage from their iPad or iPhone on the online storage area which syncs their Apple devices to their computer. This common cloud is called the iCloud. That is where common knowledge ends about this topic. However, upon further exploration, a deeper understanding is gained with greater explanation, and it is realized that cloud computing is something that is used all of the time on many levels of everyday technology. While the terminology remains cryptic to the mind of most people, the concepts behind the practical uses of cloud computing become quite clear. It is relatable and understandable. Upon this revelation, the iCloud is recognized as the tip of the preverbal iceberg when speaking about cloud computing. It is important to discuss and further understand the many types of cloud computing as well as the various applications to life through technology. This affects how information is stored online, computers are protected, information is secured, emails are processed, and many other factors that are taken for granted in the world of technology. Cloud computing is a general term used to describe how information is stored, utilized, and accessed over the internet. There is no cloud, but the word cloud gives the connotation of an abstract place which is known to exist but is too vast to touch or contain (Griffith,

Technically, Cloud is as a term of a platform, it provides, configures and reconfigures servers while the servers could be virtual machines and physical machines. Additionally, Cloud is also as a term of applications that are described as to be accessible over the internet based on the support from powerful servers and large data centers. Therefore, Cloud is quite different from traditional computing paradigms because of its scalable. Cloud is an abstract entity to supply different levels of services. Shown by figure 1, Cloud is typically providing three types of services: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

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

Cloud computing refers to the delivery of computing services over the internet. The computing services include: infrastructure, development platforms and software applications. Cloud services are privately owned for the purpose of remotely provisioning scalable and measured IT resources from data centers located around the world.

A cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resource(s) based on service-level agreements established through negotiation between the service provider and consumers. The term ‘cloud’ first referred mainly to large ATM networks. Cloud computing began in earnest with the advent of Amazon’s web-based services. Yahoo, Google, IBM, Microsoft, Sun, Intel, Oracle, SAS, and Adobe followed to offer cloud computing technologies.

The cloud removes the need for you to be in the same physical location as the hardware that stores your data. There are number of functionally equivalent services in the cloud Due to unreliable internet connections different cloud applications may receive different levels of quality for same cloud services so that optimal service selection becomes important. Cloud computing provides three main services, namely Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). In Software as a Service (SaaS), Clients can use the software that is provided by the provider, which usually need not to be installed on their own machine and they can use the software

We have all been touched in some way shape or form by the cloud. The history of the cloud dates back as far as the 1950s. Back then, a mainframe was so big it took up an entire room. It required a massive amount of space, and electricity which generated superb amounts of heat. These computers were standalone, meaning that the data was held solely with that device. In response, they developed "time sharing" methods, which allowed multiple users to share access to data and CPU time. Nowadays, this concept of “time sharing" is the premise of cloud computing. The next major event in cloud computing history occurred in 1969, when J.C.R. Licklider developed the Advanced Research Projects Agency Network (ARPANET). His desire was that someday all

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
