Cloud computing refers to an internet based computing technology where shared servers provide infrastructure, software and various other resource to customers on a “pay-as-use” basis. Cloud users need not know how the resources are managed. Hence they can concentrate on the business functionality of the service rather than the underlying functionality involved in the management of the resources. These customers do not own the physical infrastructure, but rent these resources from a third-party agency. This concept is widely utilised by the industry, government and in the educational sector due to the ability to provide robust, resilient and scalable computing power. The resources are provisioned to the user based on determining the required computing resources by the customer.
Virtualisation is a powerful technology which makes modern computers versatile and powerful. This technology enables an on-demand creation of a large number of virtual machines within a physical machine and can be implemented at the server level, OS level or at the application level. Server level virtualisation is done by emulating the underlying hardware by virtualisation software. This virtualisation software is referred as a Hypervisor or a Virtual Machine Monitor (VMM). In OS virtualisation, the virtualisation platform runs on top of the host OS which relays and co-ordinates various resource requests from different Virtual Machines (VMs). Application Virtualisation enables applications to run on
Cloud Computing is a wide term that defines an extended kind of services. In order to actually comprehend how the Cloud can be of worth to an association, it is the first significant to understand what the Cloud truly is and its diverse mechanisms. The different categories of Cloud Computing services normally mentioned to as
Cloud computing has been defined by NIST as 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 or cloud provider interaction. Cloud computing can be considered a new computing paradigm insofar as it allows the utilization of a computing infrastructure at one or more levels of abstraction, as an on-demand service made available over the Internet or other computer network.
Cloud Computing, also known as ‘on-demand-computing’. It is a computing that based on internet to share resources, information, and data with other devices on-demand. It is a model that enabled everywhere, computing resources such as servers, networks, applications and storages that are configurable can be shared once demand with access and provision rapidly and released with minimum effort of management, and different services are handed through Internet to the computer of organization. Cloud Computing depend on sharing computing resources instead of using personal devices or local servers to handle applications.
Cloud computing is one of the newest major evolutions in the technology industry. It is a paradigm where computing resources become available at any time, from anywhere just having an Internet connection. The cloud eliminates the need to be physically close to the hardware containing the data user wants to obtain. It can own both hardware and software necessary to run business applications. Cloud service also reduces costs for a company, by excluding the need to buy additional servers and memory storages. Furthermore, because this method of computing uses the pay-as-you-go payment method, it charges organisation based on the usage. This means that business can purchase more space or reduce their subscription as it is required
Cloud computing, in its most basic form, is “using computer services [such as computer and data storage, management and processing] that are delivered over a network” (Kim & Solomon, 2013, p. 189). For example, an organization may require a great deal of storage for their data but may not want to purchase the servers, the physical space for the servers, or the personnel to manage the infrastructure. Instead, they take advantage of the many cloud computing options and outsource their needs, hiring someone to do everything off-site usually with the goal of reducing their overall cost of ownership. As defined by the National Institute of Standards and Technology (NIST), cloud computing has five essential characteristics, three service models, and four deployment models (Mell & Grance, 2011) which will be covered, briefly, in the next few sections.
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.
Cloud computing an evolving term that describes the event of the many existing technologies and approaches to computing into one thing totally different. Cloud separates application and therefore the resources with info from the underlying infrastructure, and therefore the mechanisms wont to deliver them. Cloud enhances collaboration, agility, scaling, and availableness that provides the potential for price reduction through reduced and economical computing. The word Cloud describes the employment of assortment of services, info, infrastructure comprised of pools of network, info, and storage resources. These elements are often quickly organized, provisioned, enforced and decommissioned, and
Cloud computing can be defined as a model for enabling pervasive, convenient, on-demand network access provided to users to provide a shared pool of configurable computing resources. Networks, Storage, services, and applications make a part of these network sources. (Mell & Grance, 2011). In general terms, cloud computing can be stated as the process by which the users with the help of a web browser over the internet can remotely access data and program applications. A few characteristics of cloud computing are:
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
The virtualization is vendor divides the server into many small sections, which can increase the speed to process data. When the server is overload, the network of server can transfer the data to other servers.
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 refers to the delivery of computing services over the internet. It is the use of computing services over the web located in another site or provided by a third party vendor as opposed to using one’s own hard disk, personal computer or server. Cloud services allow individuals and business organizations to exploit software and hardware that are set up by third parties at remote locations. Therefore, we can define cloud computing as computing services where a broad set of systems are connected to private or public networks, to provide dynamically quantifiable infrastructure for application, data, and file storage (Kling 2014).
Cloud Computing is one of the emerging technologies which now represent a reality and a low-cost computing power resource which has gained popularity among all business categories, especially medium and small size, governmental or medical organizations, as more people are realizing the power and benefits of cloud environments. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Clouds can be classified as public, private or hybrid
