An In-Depth Overview of Cloud Computing
An Introduction
For many of us it’s hard to imagine a world without the computer, but this technology is still relatively new. The Atanasoff-Berry Computer, developed by John Atanasoff and Cliff Berry, which is considered to be the first electronic digital computer, wasn’t developed until 1937. (Mackintosh, 1987) This development led to the creation of the modern computer, however, it wasn’t until 1973 that Vint Cerf and Bob Kahn laid the groundwork for what we now call the internet. (IHF, 2016) They created network protocols, enabling computers everywhere to connect and share information with each other. These protocols consist of a set of rules and standards to eliminate communication failures.

Several computing paradigms or models have been developed which maintain the distributed architecture manifest in this network system. These include Peer-to-Peer, Cluster, and Jungle Computing, as well as Cloud Computing which is built on top of grid and utility computing, as seen in Figure 2. (Kahanwal & Singh, 2012)
Anatomy of a Cloud
Cloud Computing is a recently emergent paradigm whereby services, such as data, programs and hardware, are managed and delivered over the internet. These services are provided to computers and other devices on-demand, like the electricity over the grid. This model offers users not only services, but unlimited computing power, accessed from anywhere in the world via a web browser. Instead of relying on the power of a local, individual device, computing power is distributed, virtual and scalable, enabling users to access the computation, storage and other application resources on-demand. (Sun, White & Gray, 2011) According to Carl Hewitt, “Cloud Computing is a paradigm in which information is permanently stored in servers on the internet and cached temporarily on clients that include desktops, entertainment centers, table computers, notebooks, wall computers, handhelds, sensors, monitors, etc.” (Hewitt, 2008)

Cloud computing is storing and surveying data and programs over the internet rather than the computer's hard drive. Moreover, the cloud is a personification for the internet. It is linked to flowcharts and presentations that epitomize a huge, server-farm infrastructure of the internet as a puffy, white cumulus cloud, acquiring connections and dispensing information as it floats.
Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but
In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer 's hard drive. What cloud computing is not about is the hard drive. When someone tries to store data on or run programs from the hard drive, it is called local storage and computing. Everything end users’ need is physically close to them, which means accessing your data is fast and easy, for that one computer, or others on the local network. Working off your hard drive is how the computer industry functioned for decades; some would argue it 's still superior to cloud computing, for reasons I 'll
In doing a small business, most small companies usually have a lot of stuff to be stored safely including their application, files, data, business record, customer's information, and to name a few. As a result, most of the small businesses would continuously have problems finding space for all their necessary data when there is a disaster happen. In a realm of science fiction has become a reality with cloud computing which allows all kind of information to be widely and safely stored on the infinite space of the World Wide Web instead of in a limited area of physical drives. Therefore, many small businesses have been moving to cloud computing to keep their business sustainability and experiencing the new technologies that were never
I have put together a short research paper on a few software programs geared towards the further success of our company. I have researched cloud computing, electronic records management, decision support system, computer integrated manufacturing, and supply chain amangement. All of these applications could bring us closer to our goals set by the company and could also ensure our status as one of the top aviation manufacturing companies. I have listed each applications target and use along with how I believe it could help our company.
Cloud computing combines a number of computing concepts and technologies in objective to provide secure, quick, convenient data storage and net computing service with all computing resources visualized as services and delivered over the internet. Cloud computing has brought financial benefits and promises to many business and organizations a way to enhance their information technology such as collaboration, agility, scalability and availability without heavy upfront capital costs in servers meanwhile achieving minimal management effort for service providers.
According to the definition of the U.S. National Institute of Standards and Technology (NIST, 2011), “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 collected of five essential characteristics, three service models, and four deployment models. Moreover,
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 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.
user. Here in our paper the TPA audits the requested user’s data without reading the actual content of the data of the requested user so that preserving more privacy and auditing in a effective way so that the client gets the required results so that he user can take his further steps in improving their data security.
Abstract- In the age of large data and the large number of users around the world, cloud computing has emerged as a new era of computing. Cloud consists of a datacenter which in turn consists of several physical machines. Each machine is shared by many users and virtual machines are used to use these physical machines. With a large number of datacenters and each datacenter having a large number of physical machines. The VM allocation becomes an NP-Hard problem. Thus, the VM allocation, the VM migration becomes a trivial task. In this article, a survey is carried out on cloud computing in energy cloud, based on scalable algorithms. To solve NP-Hard problems, there are two ways to either give an exact solution or to provide an approximation.
When computer services are offered physically, users have access to the resources that computers use. The services include network, storage and operating system. The term cloud computing refers to the offering of such services over the internet. Many companies charge money for their offered cloud services while others don’t. Cyber-forensic investigations have been affected by cloud computing since the beginning of the cloud. Computer Forensics is based on the investigation of crimes or policy breaches that are done through the examination of electronics and computers and other storage devices. This paper seeks to access the impact of cloud computing and storage on cyber-forensic investigations.
The integration of mobile devices with our daily life (e.g., smart phones, smart watches, tablets, etc.) has eliminated the location and timing restrictions on access to variety of services such as social network, web search, data storage, and entertainment. Limitations on resources (such as battery life and storage) and the need to global scalability of services have motivated companies to rely on cloud computing. Cloud computing has created a new paradigm for mobile applications where computations and storage have migrated to centralized computing platforms in the cloud. Cloud providers such as Google, Amazon, and Salesforce offer clients the access to cloud resources in various locations and allow them to acquire computing resources
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,
This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud
