Cloud Computing Essay

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 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]:

The national institute of standards and technology (NIST) defines cloud computing as “a model that is meant to enable convenient access to a network that is on demand to a pool of shared computing resources that are configurable” (Jansen & Timothy, 2015). Computer system resources includes, but not limited to, storage, system servers, applications, services, and networks. Cloud computing allows these computing resources to be accessed virtually anytime, anywhere. Cloud computing opens up new possibilities in the field of information technology that many of us have or will experience. As the clients or the customers are very excited about the numerous opportunities that come along with the cloud computing technology such as a reduction in the costs of capital, and the opportunity of divesting themselves of management of infrastructure, and a massive focus on the core competencies, and most importantly, the agility that is usually offered by the provision of computing that is on-demand, there are challenges and other numerous issues that need to be looked into and addressed before a universal adoption might happen (Jansen & Timothy, 2015).

Cloud computing allows a user to store and access data and programs over the internet instead on their computer hardware (Griffith, 2015). The user is then able to access from anywhere or any internet-enabled device. There are three categories of service in cloud computing: SaaS stands for Software as a Service; IaaS is Infrastructure as a Service; and PaaS is Platform as a Service. Until recently, most users stored and accessed their programs via their hard drive, also known as local storage. What began as an alternative delivery system is swiftly becoming a way for Enterprises to reduce their IT spending while still providing multiple applications to various users. If a service has the following

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).

Widespread usage of could computing is made possible via the internet. It is the most common way to have access to cloud computing resources. However, there are many people who are not familiar with terminology and concepts. Therefore, they often need to be clarified. The news media representation of cloud computing can be vague or it might not be necessarily fully captured the extend of what cloud computing entails or represents. Cloud users are not familiar with characteristics, models, and services. Therefore, this following section of the research paper introduces layers and types of clouds, exploring the characteristics, service models, and deployment models in use today (“Cloud Computing for Business”, n.d.).

Companies all around the world shift more and more towards cloud computing and engage in its advancements. They notice how much simpler and easier their business can be with the use of it. For instance in the past, individuals would run programs and applications from a downloaded software on a PC physically or by server, while cloud computing permits the user access to the same sorts of utilization through the web. So anything shared through Cloud is available to be edited by whomever it is being shared to. Cloud computing also allows users to store and process their data in third-party data centers. It relies on sharing of resources to have a stable and coherent network.

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

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.

The largest Buzzword in emerging trends for the computer world is “Cloud”. Cloud computing in the future for data, services and platform. The concept of cloud computing is to make whatever aspect it is being used in available at all times and to act as a resource. Turning computing into a utility will transform how the IT industry uses services, designs hardware and uses network infrastructures. The term “Cloud” however has many meanings, but understanding what exactly is meant by cloud computing is the first step to

Community cloud: As name suggests, the servcies are provided to only particular group of members. These cloud is rarely used.

Cloud computing is an emerging technology these days. Cloud computing is the development of distributed , parallel ,grid computing and virtualization technologies.In this paper,we actually explore the architecture of cloud computing as well as we explore distributed , grid and utility computing. We also address the several popular cloud computing platforms. In this paper, we aim to point the risks of cloud computing. We identified several challenges from the cloud computing adoption perspective. However, the biggest concern i.e.security and privacy issues are the strongest barrier for the users to adapt into cloud computing systems. In this paper, we investigate several cloud computing platforms and its architecture and risks.

“Cloud computing is a model for enabling ubiquitous, 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. This cloud model is composed of five essential characteristics, three service models, and four deployment models.”

With the rapid change in processing and storage technologies and the success in the communication network such as Internet, lessen cost of computing resources, more powerful and more ubiquitously available than ever before. This technological change has enabled the development of a new computing paradigm called cloud computing, in which resources are shared by multiple system over the communication network. Cloud computing is a set of IT services that are provided to a business organizations or customers over a network on a leased basis and with the ability to scale up or down their service requirements. Cloud computing services are delivered by a third party provider who owns the infrastructure. Cloud computing has turned up as a new model for hosting and delivering services over the internet. Cloud computing becomes an attraction in the business world as it does not require plan for provision and business can be set up with a small amount.

1. Introduction The definition of Cloud Computing as issued by the U.S. National Institute of Standards and Technology (NIST) September, 2011 is: “Cloud computing is a model for enabling ubiquitous, 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. This cloud model is composed of five essential characteristics, three service models, and four deployment models.” Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It provides an easy and flexible way of storing, retrieving huge data without bothering about the resources. With
