INTRODUCTION WHAT IS CLOUD COMPUTING? 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] The three cloud computing service models NIST speaks of, also called SPI, are: Cloud Software as a Service (SaaS), Cloud Platform as a Service (PaaS) and Cloud Infrastructure as a Service (IaaS). The four deployment …show more content…
This is significant as properly optimized usage of computing power translates into less power being used by the physical hardware, the air conditioning to keep it cool and so forth, minimizing environmental damage. [2] Similarly to dealing with a utility, users of cloud computing services are charged according to their usage of these remote computing and storage resources rather than having to buy, install and manage them all themselves. This allows users a great deal of flexibility. They can scale up or down according to market fluctuations or changes of strategy. For example; consider a business that creates a new website and almost overnight find themselves inundated with hundreds of thousands of requests per day. If they were going about managing their website the traditional way in order to meet the new demand, they would have to rapidly purchase new equipment, set it up and perhaps even hire new people to administrate the website, all of which takes time. However if this same company used cloud computing they could expand their site to meet the increased demand within a fraction of the time and would then still have the option of returning to their original size with little difficulty, reducing overall costs.[3] To put it simply, cloud computing allows users to operate with a minimum set of resources and only
There are several advantages of using Cloud Computing, for example: “To begin, businesses can have lower cost computers for users.” Alijabre explains that cloud computing can be very beneficial for the businesses. Moreover, businesses will bring great amount of profit into their company, and it will be easy to use it. Alijabres goes on to provide several examples why cloud computing is better. One of of the most important reason why companies are moving towards cloud computing is the lower cost of the system. “To begin, businesses can have lower cost computers for users.” He explains that small business will not need computers that are high performance based. Business can get less expensive computers and store all of their data online instantly, without having them to worry about the space in a
Cloud computing is a model for allowing convenient on-demand access from anywhere to a shared pool of computing resources. These can include servers’ storage, networking, applications, and services that can be rapidly and easily provisioned and released.
Cloud as the term signifies means the computers in a network to be used for data storage remotely and for maintenance. The cloud computing offers reductions in costs and also has increased scalability, reliability and flexibility in its own processes, and is considered as todays one of the most exciting technologies and has seen a rapid growth over the past ten years. The Cloud computing uses advanced level of computational
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.
1. Introduction The definition of Cloud Computing as issued by the U.S. National Institute of Standards and Technology (NIST) September, 2011 is: “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
Cloud computing can assist organisations improve the creation and delivery of IT solutions by allowing them to access services more flexibly and cost effectively. In public cloud computing, services are delivered by a third party to its external customers. In private cloud computing, IT provides services to internal customers.
Cloud computing provides various services to its users through internet using a pay as per usage plan giving users the freedom to use just exactly what they want and change their requirements accordingly based on their usage. Hence avoiding the huge costs that incur to setup and monitor a server system which has a limited scalability. Even though Cloud Service
Cloud Computing is a paradigm that enables access to shared pool of system resources which are provisioned with minimal management effort.
The aim of Cloud Computing is to let users to take advantages of all the technologies, without the require of professional knowledge of each of them. The goal of cloud is to reduce costs so that users can concentrate on their main business without get impeded by professional IT barriers.
“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.

Cloud computing provides simplified management and maintenance by have all IT resources, agreements, and infrastructures centrally managed. All maintenance and updates are done by the CSP, allowing the business to have a simple web-based interface to access all applications, software and services without any installation in a timely manner. (Advantages and Disadvantages of Cloud Computing, 2015). Cloud computing also allows easy access to share files from any device with an internet connection. This makes it very simple to manage data and documents from any location at any time.
In plain terms, Cloud Computing enables end users to utilize parts of bulk resources and these resources can be received quickly and easily.
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.
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.
