Chapter 2 Literature Review ______________________________________________________ 2.1 Overview 2.1.1 Cloud Computing Cloud computing is 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 service provider interaction[NIST]. Cloud computing is a form of computing in which large groups of remote servers are networked to allow centralized data storage and online access to computer services or resources [Wikipedia]. Cloud Computing, by definition, refers to the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing[amazon aws]. A cloud refers to a distinct IT environment that is designed for the purpose of remotely provisioning scalable and measured IT resources. The term originated as a metaphor for the Internet which is, in essence, a network of networks providing remote access to a set of decentralized IT resources[whatiscloud]. Some common services that are hosted in the cloud are desktop hosted provided by companies like AT&T, email hosted provided by companies like google and Yahoo, cloud storage provided by companies like Dropbox, and streaming music provided by companies like Spotify. These services, applications and files are stored in the cloud environment and can be accessed by users via any device, at any location. There are a
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 fairly new term used to identify a type of computer connectivity, IT services and on-demand delivery offered via the web. The way that it works is, Cloud Computing offers an easy approach to accessing servers, storage, databases and a wide set of request over the Internet. Cloud Computing also allows cloud-based service providers to own and sustain the network-connected equipment necessary for these application services. This is all done while permitting a business to facilitate and use the services that are deemed essential via a web application (Amazon, 2016).
The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “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”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology
Cloud computing refers to a computing environment where software and storage are provided as an internet service and accessed with a web browser.
Cloud Computing is a type computing that shares resources both hardware and software over the internet rather than sharing it over a local server . Users can access cloud based apps through a web browser or an mobile or laptop which makes things alot easier for the user. Lots of companies use cloud computing such as Xbox 360, there online cloud data service allows users to use their Microsoft accounts anywhere.
Cloud computing is where an individual can save data on a server rather than their own system, such as on their hard drive. This allows more data to be created without it effecting the individual’s computer. An example is one drive by Microsoft.
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.
Cloud computing, is mostly referred to "the cloud," and is a technology that offers a lot of demanding computing services and resources such as applications, networks, etc that are accessed via the Internet (IBM Cloud, n.d.). The most known providers or vendors of cloud computing are Apple, Google, Microsoft, Amazon, IBM, Interoute, and so many more. The services that cloud computing provides are: communication project
Cloud computing enables you to get to your information and projects outside of your own processing condition. Instead of putting away your information and programming on your PC or server, it is put away in 'the cloud'. This could incorporate applications, databases, email and record administrations.
Cloud computing refers to the delivery of computing services over the internet. The computing services include: infrastructure, development platforms and software applications. Cloud services are privately owned for the purpose of remotely provisioning scalable and measured IT resources from data centers located around the world.
Cloud computing is the practice of using remote network servers via the Internet to manage, store and process data. Many businesses use cloud computing because in a lot of cases it can be cheaper, faster and easier to maintain then local servers. Since its introduction cloud computing has grown to not only be used by businesses but also regular Internet. Cloud computing services such as Google Docs, Dropbox and more are one of the reasons for this shift. They allow the user to access their files whenever and wherever they want.
Cloud computing is the idea where application runs on a remote server that is provided as a commercial service by a company rather than an institution or individual’s local machine. Cloud computing has made possible to provided Software as a Service, Platform as a Service and Infrastructure as a Service (Beaty, 2013,p. 88-93)
The overall concept of cloud computing is one which is based on a new architectural model of computer resources which means the data is stored remotely, but is provided to users as if it was stored locally. This new concept has been described as being "a style of computing where massively scalable IT-enabled capabilities are delivered 'as a service' to external customers using internet technologies" ("Will IT of the Future Have Its Feet Firmly Planted in the "Cloud"?," 2008), in a dramatic shift from traditional computing methods. Cloud computing is also able to provide services to the end user seamlessly, to serve applications from a central location, regardless of the user’s location. There are numerous services such as
Cloud is a trending term across the Internet and is often confused with data center and virtualization. To begin with, data center and virtualization are centric to the cloud, but scope of the cloud as a whole is much wider. To put in simple words, a cloud is a pool of large configurable resources that are available on demand over the Internet. These resources can be available in the form of storage devices, servers, processors, and network interfaces [4]. Packaging these resources to provide services to end-users is termed as cloud computing. The users are provided with an ease of accessibility
Cloud computing is a style of computing that provides easy access to a highly configurable pool of resources which are simple to use
