2.2. The Elements of Cloud Computing
Cloud computing as everyone knows is not a new technology however, it just surfaced the technology market space. The primary reason why cloud computing still sounds like an alien language to some business executives is that they can’t grasp easily the anatomy of cloud computing. As earlier flashed-on in the introduction part of this book, understanding the arrays of services offered, the way those services are distributed game players in cloud computing is important.
When we speak cloud computing, we are about multi-tenancy and a server host; so, the service is always never really owned by clients who want to rent it. All cloud computing(CC) platforms and infrastructures-as-service operates on a

IaaS provides support for all IT requirements, like CPU, memory, storage. In a deeper analogy of cloud computing, we can observe an internal arrangement like the PaaS and SaaS accruing services for IaaS for their own customers.
3. ANALYSIS OF CLOUD COMPUTING
Cloud computing can be a very damning topic to an ordinary manager. In fact, it takes above average knowledge of computer terminologies and concepts to fully grasp what cloud computing is all about. The focus of this section, however, is to outline the basic that is needed for an average manager of a company in other to get the best cloud services for his/her company. There are many cloud computing vendors out there, and selecting the best provider can seem daunting. This doesn’t have to be. The focus should be on the QoS requirements which should be discretely organized in an order to compare multiple service provider against company’s QoS. Defining the standards for company’s QoS would be another challenge a manager might face in an organization. According to CSMIC (Cloud Service Measurement Initiative Consortium) have established a rather complex but easy framework for measuring cloud services providers. A Service Measurement Index (SMI).
The SMI framework has been a good framework because enables the company to ask seven very important questions. Accountability, can we count on this very provider and this is determined by considering their suitability, compliances, contracting experience,
This case gives us a fundamental understanding of the concept of cloud computing and presents the advantages and issues of this IT infrastructure. This case gives a clear vision of the company’s current situation. Three main questions to consider
The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of
Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.
The cloud computing industry evolved over the past fifteen years and according to (White, 2013) in the article, “A Cloud Retrospective”, the cloud industry was introduced out of the dot.com bubble burst at the beginning of the twenty-first century compelled internet-based companies to modernize their Information Technology (IT) Architecture and find more efficient IT operating solutions (White, 2013). (White, 2013), writes that Amazon entered the cloud market by introducing its Amazon Web Services (AWS) in 2006. (White, 2013) states in 2007 there were disagreements by the experts on the true definition of cloud computing. In 2008 the cloud market expands to include more vendors (White, 2013). (White, 2013)
By 2020, Forbes (McKendrick, 2012) has estimated that the cloud market will be worth $270 billion; this suggests that the market is expanding rapidly and users are becoming more aware of this feature. Many people, though, still ponder over the exact purpose of cloud computing: Cloud computing is a group of offline servers that are networked together to allow data to be stored centrally. For example, Drop box is an established cloud storage company that allows users to store documents, images and videos on their servers. This type of cloud computing is known as ‘Software-as-a-Service’, which are business applications that are hosted by the provider and delivered as a service (Hurwitz, 2010). Hurwitz also mentions two other types of cloud computing: ‘Platform as a Service (PaaS)’ and ‘Infrastructure as a Service (IaaS)’. ‘Platform as a service’ is where the consumer will create an application, using tools and software from the provider, then the provider will administer the consumer with networks, storage and servers. ‘Infrastructure’ as a service is where the provider will provide the consumer with physical computer or virtual machine.
The lack of a clear and widely accepted definition has posed a barrier to talking about cloud computing in general. Clearly “cloud computing" is an evolving term, defined more by usage than by
Cloud computing has become a major topic of discussion and debate for any business or organization which relies on technology. Anyone connected to the Internet is probably using some type of cloud computing on a regular basis. Whether they are using Google’s Gmail, organizing photos on an Apple iPhone’s photo steam or searching the Web with Bing they are engaged in cloud computing. The interesting thing about cloud computing is it did not start as a technology for the business enterprise, but was driven by the public with services like Facebook. Over the last few years businesses have started to see the value of cloud computing causing it to become a major technology solution for businesses and organizations around the world.
Several years after the emergence of cloud computing, most of people still confuse with its concept because different research institutes defined the term differently. With the development of cloud computing, its concept evolves gradually in years. According to the Wikipedia, the most recent definition of cloud computing is “the delivery of services of the computing a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network (typically the Internet).” Cloud computing, in one word, was termed as the many different types of virtualized applications and services that are moved into the “cloud” – a metaphor for the internet. Cloud computing providers maintain and control physical servers, and data is processed in the “cloud” provider’s environment which also delivers hosted services. For the user, the entire computing infrastructures virtually reside “in the cloud.” In many cases, devices that used to access these services and
The next area the business must evaluate is performance over time, cloud providers performance and ability to provide highly available services are critical, this is one major reason to moving to the cloud is the ability to have highly available services. The company must assess and determine what the cloud service provider can provide in terms of uptime along with the amount and location of data centers. In addition, the company must understand what tools and methods the cloud service provider provides the company to monitor the services and availability of the cloud network along with SLA’s that can be utilized to protect the company.
In this paper, I will briefly introduce what cloud computing is and some of its fundamental concepts (service models and deployment models). The later part of the paper will mainly focus on examining cloud computing impacts on business – the benefits it will bring, and the risks and challenges that go along with it.
There are different types of cloud computing services available on the market which falls into one of the following categories.
Cloud computing is a technology that has come full-circle in recent years. Computer equipment used to be too expensive for an average individual to own. The original industry model was a computer mainframe with dummy terminals. This fit the technical definition of Cloud Computing in a primitive sense because all data was stored and accessed from the mainframe. With the advent of the microprocessor, MS-DOS and Windows, hardware and software prices dropped and computers became commonplace in businesses and homes. This transition led to a model with personal computers storing data locally and not being connected to each other. Then as the Internet was created and the World Wide Web was developed to explore it, Personal Computers became
The term “cloud” was coined from the computer network diagrams which use it to hide the complexity of infrastructure involved. cloud computing provides software, platform and infrastructure as a service. its main features include resource pooling, rapid elasticity, measured service, on-demand self service and broad network access. so, a cloud is a collection of hardware and software that runs in a data centre and enables the cloud computing model. A cloud reduces capital investment, hardware cost and software licence cost.
Cloud computing customers do not need to own the physical infrastructure; rather they use the resources from a third-party provider on rental basis. This helps them to avoid huge effort for the setup of the infrastructure. The End-user consumes the resources as a service and pay only for resources that they consume. Most cloud computing infrastructure consists of
