Role Of System Administrator : Cloud Computing

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

The issue of cloud computing refers to either the applications that are delivered in the form of services on the internet or the systems software and hardware in the data centres that are meant for the provision of those services (Dinh, et al. 2013). As outlined by NIST, there are usually four main cloud delivery models. The cloud models are

Cloud Computing has been a buzz world in the past few years. The use of this technology increased considerably when we made huge progress in this domain, reducing the cost for everyone. Today, Cloud Computing is widely used all across the world by a lot of companies such as Microsoft, Facebook, Amazon, etc…

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:

What is cloud computing? Cloud computing is a new process of managing, storing, and accessing data and programs over the internet instead of through a local computer hard drive or office network. (Griffith, 2016). A newer process developed in the early 2000’s to better help organizations as technology continues to evolve. Cloud computing is having the ability to access your information through an internet connection from anywhere at any time (Griffith, 2016). Of course, as with most all technology there are many advantages as well as disadvantages. Throughout this paper we will look at some of the top advantages and disadvantages that come with the process of utilizing cloud computing.

Cloud computing has proven that it is a technology that is here to stay and has shown to be a powerful game changer in modern business. It is a key component in allowing a organization to operate in ways never before imagined; however, with any new technology it is important to be educated about the technology and situation to be able to effectively leverage for an advantage. Through discussion of the technology, combined with potential security issues, strengths and weaknesses, a more thorough understanding of cloud computer

Cloud computing is where software applications, data storage and processing capacity are accessed over internet. Organizations use cloud computing in a variety of different service models like IAAS, PAAS and SAAS. These are the three building blocks of cloud computing.

Recently, Cloud technology has turn out to be a huge buzzword, and with good reason. The cloud already creates remarkable value for clients and businesses by making the digital world simpler, faster, more powerful, and more efficient. In addition to bringing valued Internet-based services and applications, the cloud can provide a more

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.

of organization, are discussed. Characteristics of cloud computing discussed to get idea what the cloud computing is all about using. In addition to that, deployment model of cloud computing is discussed in greater detail to explain cloud computing can be used as public, private or hybrid type. Based on service delivery cloud computing divided into three types Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) are explained further in this section.

The cloud computing, in comparison with personal computing, offers an extensive range of competencies. Cloud computing is defined in broader terms as “A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet.”12

Cloud computing is the new buzz in the recent days and cloud computing allows users to share files and applications over the internet. In the following pages we will discuss about the cloud computing its pros and cons, the security risk and how to overcome and use its resources for the best advantage of organizations. It is attracting much of the attention now-a-days which can be seen by observing the big names of the IT industry like IBM, Microsoft and Google investing millions of dollars into research on cloud computing.

Since the innovation of the internet, people in computing fields have seek to find storage solutions that could provide users and organizations with capabilities to store and process their data distant from end-uses. Since 2000s, cloud computing has come into existence, later on, became business feasible through the observation that organizations start to substitute from self-owned hardware and software to subscription mode based models. Thus, we’re currently on the shift to cloud computing that may cause a dramatic growth in internet-based IT services in some industrial areas and some decline in other areas. By definition, cloud computing is an internet based computing for storing or sharing used computer or applications on multiple servers.

Cloud services are divided into three model based on the resources or services provided. Figure below shows the service models as layered architecture with the service contents.

This technology named as Cloud Technology or Cloud Computing was just a buzzword during the early 2010 but became more prominent and was widely adopted by 2012.Internet in other terms can be termed as a “cloud”. There are two words that define Cloud computing the most: Web Applications. Any organization using huge clusters of computers which require high performance through the host of services available use cloud computing. [1, 2]
