Factors Influencing the Adoption of Cloud Computing by

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of

This research paper tackles the issues that faces Cloud Computing today and gives the experts and industry’s point of view on the matter. The aspects explored are the significant industry questions that have risen about the use of Cloud Computing, business value, organization impact, adaptability, limitations, initial cost of implementation, and the severe business security risks

• On demand service- Cloud computing provide services to users on their demand .Users can access the services as they want.

"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, 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, or “the cloud”, is 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 service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.” [1]

Cloud computing can be defined as the large-scale, shared IT infrastructure which is available over the internet it helps is transforming the way corporate IT services are delivered and managed.

The growth of cloud services has begun a transition of companies to partially or completely move services and abandon on-site data centers in favor of a cloud based solution. This movement has become a phenomenon for businesses; however, before a business implements any type of cloud solutions it must consider several things.

According to Squicciarini, Oliveira and Lin (2016), cloud computing as a paradigm should not be viewed as a new technology but appreciated as an extension of how the Internet can be used. Cloud-based services are anchored on the idea of using a network of remote servers hosted by third-party companies to store, manage and process data as opposed to using in-house servers.

The term ‘cloud computing’ gets tossed around in media and business settings, and while everyone seems to know generally what it is, not everyone is aware of how to use it, much less how to implement it in a safe way that still enables it to provide the full benefits of storing data in the cloud versus storing and managing it on-site. Cloud computing has many benefits for businesses, such as allowing them to store information and be managed by an outside company, which eliminates the cost and effort of a company having to buy servers, install and configure them, and then hire IT staff to continue to maintain them. According to a study of over 1,300 U.S. and U.K. businesses, 88 percent reported that they saved money using cloud services,

Cloud computing is real time computing services that are delivered over the Internet. Such services include servers, storage, databases, networking, software, and more (Microsoft Azure). Cloud computing is offered by service providers that typically charge a pay per use fee for service usage. Cloud computing is heavily integrated into daily technology use from email clients to collaborative text editing software such as Google Docs. Cloud computing can virtualize an IT system or essentially turn software virtualized and real time.

The central theme of this essay focuses on the impact of cloud on the organization’s network infrastructure. While going through the impact we will also analyze how to optimize network performance for cloud and we will also discuss about how the cloud impact the lifecycle orchestration and the organization. The key aspect o the cloud is discussed in detail with suitable examples.

Infrastructure as a Service (IaaS) is a cloud model which allows organizations to outsource computing equipment and resources such as servers, storage, networking as well as services, such as load balancing and content delivery networks. The IaaS provider owns and maintains the equipment while the organization rents out

According to the US National Institute of Standards and Technology (NIST), cloud computing has a few standard characteristics. First, they provide on demand self-service, which means that their customers can manage, increase or decrease their server time or network storage on a need-to-need basis by themselves. Second, they provide ubiquitous network access, meaning that the resources can be accessed using standard internet devices, including mobiles. Also, the user does not know where the computing server is located. Another characteristic is rapid elasticity, meaning that the resources can be changed quickly and easily to meet user demand. The last characteristic is measured service, meaning that the customers are only charged for the amount of resources they use, no more and no less. (Laudon & Laudon, 2016)

The three service models are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). The aptitude that SaaS gives to the user is to use the provider’s applications functioning on a cloud infrastructure. The applications are accessible from any connected client devices. The user does not do anything with the cloud
