The Cloud Of Cloud Technology

Cloud computing is the practice of using remote storage for applications and data. The idea itself is not a new one; it has been in use for many years albeit under different names. In the earliest days of the computer age machines had to be physically large to contain the hardware required to do their jobs. It was impractical and prohibitively expensive to provide one of these mainframes for individual users; not to mention for what they were used for, unnecessary. Instead, one central computer was wired to several terminals that users could interface with. Typically, only large organizations such as, major corporations or government agencies could afford one of these machines or had need of one. This was the birth of cloud computing. Until the early 1980s this system was typical for any organization requiring large amounts of processing power. It was considered unnecessary and difficult to put the nuts and bolts of applications onto users’ desktop machines. Rather, by keeping applications in a central location, they could be managed and updated more easily and large amounts of storage space and processing power were not needed on desktop machines. Indeed, before this time there were no desktop machines mass produced that could achieve this level of power. This was about to change.

Within the past 10 years our societies technological advantages have been somewhat space age like, even alien like characteristics. Technologies, which ten years ago only existed in our dreams but yet, have become reality. Things like, the revolutionary iPhone and its almost seamless touch-screen tech; as well as the new advancements in our cultures most prized possession, The Internet. In this subject-based paper, I will take a closer look into a fairly new emerging technology, which is simply referred to as…Cloud Technology. The synopsis will cover, what and how cloud technology works, its

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

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.

In 2006 Eric Schmidt Google’s CEO used the term cloud to describe the business model of providing services across the internet. Since then cloud computing has become the most popular IT standards. It is used by various organizations to consume shared computing and storage resources in less time and reduced cost.

Cloud computing is a fairly new technology; it is separated into three separate categories. The first is Infrastructure as a Service (IaaS) this service is mainly used by companies to cut the cost of buying computer hardware such as servers , they also save on maintenance cost since the virtual servers is maintained by the company that rents them [1]. The second category is Software as a Service (SaaS) this service deals with providing software which is usually rented, this allows users to have multiple users whereas normal software limits the amount of users [1]. The last category Platform as a Service (PaaS) is used as a tool to develop software [1]. All these services offered by Cloud Computing are done virtually where you access

Cloud computing refers to the technology in which the entire range of the services such as application, infrastructure and the platform are accessed with the help of the internet. The access to these services are provided by the major contributors such as Google, Apple , Salesforce.com, Amazon and Microsoft and the access to these services were entirely out of reach if these major providers would not have contributed in it to a large extent. The entire range of the services provided by the cloud computing includes the activities for the business operations. Collaboration; communication project management, data analysis; data scheduling; storage and the sharing are supported by the cloud services. The access to these 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.

The cloud computing, in comparison with personal computing, offers an extensive range of competencies. Cloud computing is defined in broader terms as “A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet.”12

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,

Cloud computing paved the way to the specific type of service known as Software as a Service (SaaS) in the 1990s, as well as programs like Salesforce, which gave businesses the ability to have better “customer relationship management” (Goodrich 2013). As more SaaS programs became available, it was clear that agencies like The National Institute of Standards and Technology and Legal Cloud

In fourth section, the article discusses cloud offering under three types of service models. These are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). IaaS provides fundamental computing resources (storage, network, processing) as a service where subscribers are able to deploy and run their choice of operating system and software applications. PaaS is the next level of service, where subscribers have an operating system in addition to hardware as a service, and have control over changes in the application and hosting environment. SaaS is the third level of service, in which client get software also as a service in addition to an underlying operating system and hardware. All the services offers pay-as-you-use.

Cloud-based applications—or software as a service (SaaS)—run on computers in the cloud that are owned and operated by others. These computers connect to users’ computers via the Internet and, normally, a web browser. There is no software to purchase, install, update or maintain. This is handled by the service providers. By using the internet browser, applications, and data are accessible from any connected computer. Because access is through the web browser, data is in the cloud. This prevents any data from being lost if there is any issue or problem with the
