Cloud Computing Challenges And Challenges

Cloud computing is a one of the most talked of topics in the field of Information Technology in recent times (Keyun, Joe, Taha, & Ibrahim, 2013). This subject area of cloud computing basically is a term used to describe computer resources available as a service accessible over a network (Darren & Kim-Kwang, 2013). The National Institute of Standards and Technology (NIST) define cloud computing as a model for enabling ubiquitous, convenient, on-demand network access on 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 (Peter & Timothy, 2011). Due to the attractive nature of the model there has been rise in the use of cloud computing. Gartner, an IT research and consulting firm, says that cloud computing is growing will become the bulk of IT spend by 2016 (Gartner, 2013).

Cloud computing is best described as the delivery of computing services on the internet platform. This particular technology has allowed households to use hardware and softwares as services off remote sites managed by third parties. Its model makes provision for ease in access of resources from anywhere with access to network connection. Cloud computing makes provision for a shared pool of resources such as space for data storage and platforms for user and corporate applications amongst others.

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 a model for enabling ubiquitous (present everywhere), 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 [1]. Types of Cloud computing models are Public cloud, Private cloud and Hybrid

“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 is composed of five essential characteristics, three service models, and four deployment models.”

The boom in the cloud computing world has led to a new era of on demand delivery of hosted service over a shared network. Cloud computing is a complex infrastructure of software, hardware and storage that is available as a service. It has flexibility rendering user to customize the service suited to his needs. Innovations in virtualization and distributed systems have paved the path for interest in cloud computing.

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 on the rise. Cloud computing is a style of computing where software and virtualized hardware is provided over the internet (O’Brien & Marakas, 2011). The seven most common uses of cloud computing include: infrastructure as a service, private cloud or hybrid cloud, test and deployment, big data analytics, file storage, disaster recovery and backup (Ferkoun, 2014). The biggest advantages of cloud computing include increasing competitiveness through cost reduction, greater flexibility, and elasticity and optimal resource utilization (Ferkoun, 2014). Cloud computing basically uses the internet to provide for the computing needs of the end users.

This paper gives an overview at the structure and working of the idea of cloud computing. This paper consists of the basic idea of cloud computing, its various characteristics along with its components, architecture and also the different types of cloud computing. In this paper the various terms and various concepts related to cloud computing are explained. This paper concludes with the current research and projects that are being performed in cloud computing.

Cloud Computing is a new paradigm of large-scale distributed computing which is rapidly becoming one of the hottest topic among business organisations (Pallis, 2010), and represents a fundamental change in the way of Information Technology (IT) services are invented, developed, deployed, scaled, updated, maintained and paid for (Martson et al, 2011).

In this paper, I will briefly introduce what cloud computing is and some of its fundamental concepts (service models and deployment models). The later part of the paper will mainly focus on examining cloud computing impacts on business – the benefits it will bring, and the risks and challenges that go along with it.

Cloud computing has rapidly increased their services for IT infrastructures solutions in the last years, reducing cost of investment of supplies and maintenance becoming a promising concept in the business and IT industry. The cloud provides shared data center, automatic upgrades, security and performance. However, cloud’s safety and standardization have been a challenge when different types of clouds need to be connected. Resource management issues as Quality of service (QoS) and the increasing of complexity and functionality failures are a constant in cloud computing environments, and should be considered by customer when looking for cloud solutions to adapt their organization’s requirements. This paper will explain the

Cloud computing has been ideas as the next generation paradigm in computation. Cloud is an environment of the software and hardware resources in the centers of data that provide diverse services over the network or the Internet to satisfy user’s requirements [1].

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

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.
