Introduction Of Cloud Computing

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 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 quickly evolving and expanding, thus it’s hard to precisely define this technology (Pallis 2010). However, the main features of cloud computing can be identified according to national institute of standards and technology (NIST)’s definition:

Cloud Computing is a process of delivering a companies or individual’s applications and documents from any place, at any time, on any device. It is also a process in which hosted services are delivered through the internet.

"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

Cloud computing refers to the technology in which the entire range of the services such as application, infrastructure and the platform are accessed with the help of the internet. The access to these services are provided by the major contributors such as Google, Apple , Salesforce.com, Amazon and Microsoft and the access to these services were entirely out of reach if these major providers would not have contributed in it to a large extent. The entire range of the services provided by the cloud computing includes the activities for the business operations. Collaboration; communication project management, data analysis; data scheduling; storage and the sharing are supported by the cloud services. The access to these cloud computing

Cloud computing is a general term that describes a type of computing that provides services over internet. The roots of cloud computing starts from a concept formulated by J.McCarthy in the 1960, the utility computing or the idea that computing could be organised as a public utility such as water or gas. This concept with many others such as network-centric-architecture and grid-computing can be found under the umbrella of cloud computing (Marinescu, 2013).

Cloud computing has become a compelling paradigm for delivering and managing services over the internet. Although it might be difficult to define cloud computing, one simple definition of the term is virtualized third-party hosting. In simple terms, instead of renting the entire or actual physical server, one rents a certain proportion of server resources. The client’s server runs within a virtual container that may be moved from a physical server to another without service interruption. Cloud computing has changed the entire landscape of Information Technology, and it is finally actualizing the long-standing promise of utility computing. This paper serves as a comprehensive overview of the cloud computing technology; definition,

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 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)

Cloud computing is the growing method of computing adopted by many organizations nowadays around the world. The word ‘cloud’ refers to the network, the servers providing the cloud services can be located anywhere in the world (Garg & Buyya, 2012). The services are provided through internet and made available to the end users. Several definitions are given for the cloud computing in the literature. According to (Mell & Grance, 2011), “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. This Cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.” Different advantages of having cloud computing includes, services are available on demand, the users have to pay only as per the use and the services are accessible from anywhere as it is available over network. There are different service models and deployment models available for cloud computing.

Cloud computing is an Internet-based type of computing through shared computer processing resources. Data is availed through the device on demand. In cloud computing provision of resources is achieved through an Internet connection. Resources shared include servers, storage, services and applications.

Cloud computing is a part of internet growth, it’s the next generation of internet. Cloud computing deliver everything –computing resource, infrastructure, application, and business process to personal collaboration – and can be access as service wherever and whenever through various devices. The cloud itself is a set of hardware, networks, storages, services, and interface that enable to delivery of computing as services based on user demand. (Hurwitz, J, 2009)

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 promotes availability and is composed of five essential characteristics, three service models, and four deployment models. Essential Characteristics: On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider. Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones,

The National Information Standards and Technologies defines Cloud 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.” (Howell 33).
