It is very hard to imagine a world without computers! Everywhere you look computers are at work attempting to provide one service or another and make our lives easier. Computers, in one form or another can be found in vehicles, from cars, trucks and motorcycles to larger scale methods of transportation such as airplanes and trains. They are in your television set, your VCR, etc. But when we conjure up the image of a computer usually our first thought is of a PC, otherwise known as a personal computer. Personal computers have completely revolutionized the way the world, lives, works and conducts business. Strictly-speaking, computers arrived on the scene way back in 1936 when one Konrad Zuse produced what was then called the Z1 computer. …show more content…
How exciting and wonderful it would be if the computer were nothing more than an Internet browser “a digital window pane on the web.” Imagine being able to access all of your personal data at any given moment. Imagine having the ability to organize and mine data from any online source. Imagine being able to share that data—photos, movies, contacts, e-mail, documents, etc.—with your friends, family, and coworkers in an instant. This is what cloud computing promises to deliver. Cloud computing can broadly be described as on-demand computing, for anyone with an Internet connection. Access to applications and data anywhere, anytime and from any device is the potential outcome of this emerging technology. At its most basic level, the "cloud" is simply the Internet, or the vast array of servers around the world that comprise it. Whether one realizes it or not, we have all been using cloud-based services. Pretty much everyone with a computer has been. Web-based email programs, like Yahoo or Hotmail, are familiar examples of cloud-based applications. These programs live on servers, not on one’s PC, and one can access them through a Web browser.
Cloud computing is a new and much-needed technology that provides resources over the Internet and is extremely accessible to those who use the service. Applications are stored on an off-site server, thus eliminating the need to install any software on their computers for users to be able
Cloud computing is one of the fastest growing segment of Information technology today. In simple words cloud computing means storing and accessing data and programs over the internet instead on the computer's hard drive which can be accessed from any part of the world if the individual are connected to the internet or a network connection is available 24/7. A simple example of cloud computing is g-mail. With the connection of internet through any medium we can send and receive emails.
Cloud computing is a fast growing information technology trend that many companies including Google, Microsoft, and IBM are currently looking to get a stake in as demand for the service grows. Cloud computing is the concept of allowing both individuals and businesses to store data and applications on remote servers (owned and operated by a third party company), rather than on their own hard drives and data centers. The service boasts the ability to securely access data and applications from just about any device with an internet connection, allowing for such services as streaming music from a personal collection from multiple devices, and even to business
According to Lawrence Shawa, "a number of organizations I have spoken to have expressed concern about how secure their data is that is hosted in the cloud. There is sense of control that is taken from them making the organizations feel vulnerable" (Collection 2:1) Companies naturally feel a strong sense of obligation to protect their customers. Additionally, they may lose business if they have a reputation for compromising customer security.
Modern cloud computing is a delivery system for computing services either for free, or on a pay-as-you-go basis. In this system, users utilize the Internet and remote data centers to run applications and store data. Cloud technology can allow more efficient computing by removing most of the upfront costs of setting up an IT infrastructure. It also allows organizations to expand or reduce their computing facilities very quickly. Increasingly, cloud computing is perceived as a big step toward the long-held dream of computing as a managed utility similar to cable TV or electricity.(Buyya et al, 2010) Cloud computing can be defined by certain criteria. These features are what make cloud computing an attractive option for modern organizations.

Question 1. What is the most appropriate Cloud Deployment model (or combination) for BPI (Public, Private, Community, or Hybrid)?
Cloud computing is the result of evolution and adoption of existing technologies and prototypes; although the origin of the term cloud computing is unclear. In the earliest stages, the term ‘cloud’ was used to represent the computing space between the provider and the end user. References to cloud computing in its modern sense appeared as early as 1996, with the earliest known mention in a Compaq internal document (Regalado, 2011). In 1997, Professor Ramnath Chellapa of Emory University and the University of South California defined cloud computing as the new “computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone”. This has become the basis of what we refer to today when we discuss
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.

Cloud computing, a model for enabling 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 of service provider interaction. From a user 's perspective, cloud computing is the use of the application without having to understand the mechanics involved in implementing it and making it accessible. From an IT perspective, it is the opposite end of the spectrum. For IT professionals, cloud computing means understanding how to deliver the experience and meet other business goals such as service level agreements (SLAs), reducing costs, compliance
People are utilizing cloud computing without having knowledge of it. Cloud computing is getting sophisticated with each passing day. Cloud computing is described by various organizations and IT professionals in different words. According to Almadallah,M, (2014, p.1) there is a fundamental program over the Internet, which is easily accessible to everyone, and gives an approach to users to progressing data, using services, running applications and updating software whenever and wherever they need.. This is known as “cloud computing.” Data with range and trustworthiness is being delivered over the Internet by cloud computing. According to Rajaraman,v(2014, p.242).People usecloud services as operating systems that run on personal computer and administered by special software. For example, Gmail, Yahoo mail, and Hotmail are provided by Google, yahoo and Microsoft and are used to send e-mail.
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,
Security is the most important thing for an organization or and company. If a company has a very big portal then we cannot say that the company is really very big but if the security of the company should be well assured that it is safe . Hence, I can say that Security is the most important hurdle for an organization to keep its data & policies undercover so that only the recommended people can have an access to it. With their business information and critical IT resources outside the firewall, customers worry about their vulnerability to attack.
To make it simple, cloud computing is a system for users store and access data or programs over the internet instead of individual hard drive. This cloud system is composed of three parts in terms of four important features, several service models and development models, details of those components will be explained in this report.
In common usage, the term “the cloud” is essentially a metaphor for the Internet. Marketers have further popularized the phrase “in the cloud” to refer to software, platforms and infrastructure that are sold “as a service”, i.e. remotely through the Internet. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network
In certain cases, data is stored permanently. Nearly 164 Sun enterprise class servers are used in DAS architecture. The total capacity is of several TB’s. The Sun hardware uses an in-built storage management tool. Later look over a storage management application from VERITAS.
