SUBJECT: Expanded Definition of Cloud Computing
Introduction
The Purpose of 750-1000 Word Expanded Definition project is to show the readers about the use cases of a specific term in different contexts and quotes. The term I have selected for my 750-1000 word expanded definition project is “Cloud Computing”. I am going to discuss the term in my own words by comparing the term with the definitions and contextual sentences I have included on this document. In the following document, I discussed several definitions of the term, I compared several contextual uses of the term and finally I wrote my own working definition of the term.
Definitions
“An approach to computing in which the end user connects to a remote network of computers (the cloud) to run programs, store data, etc. This enables users to access large amounts of data storage and computing power from anywhere in the world without having to own and maintain these resources themselves.” (Oxford University Press,2016)
On my First definition it explains cloud computing infrastructure help users remotely to elastically run programs, databases and provide storage options to secure the data. In addition, users have access to the system anytime without the necessity of maintaining a whole data centers and servers. On the second definition, the concept of cloud computing is similar. For example- Cloud Services has five characteristics which defines the availability and compatibility of the resources and gives the privilege to interact with the services.
“According to National Institute of Science and Technology the definition of cloud computing outlines five key cloud characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.” (Derrick et al.,2014)
On this definition the author gives solid definition on cloud computing by providing its five pillars. It means cloud infrastructure provides on demand services, remotely access the network, effective resources, rapidly increase the demand of the instances (Virtual Computers), and measured services. All these services and resources help the users to effectively conduct their applications and programs without the provisioning of the servers or storage. Cloud providers do everything for them if they choose Software as Service model (SaaS). Compare to the First Definition this definition gives the broader picture of cloud infrastructure and its services.
Context
Cloud computing is the main component of the modern widespread paradigm, where resources are shared and globally accessed over the network. This has rendered the Internet a large repository where most of the available resources can be accessed “as a service.”
I have found this contextual sentence on a book called “Security for cloud computing” where this Quote explains cloud resources can be accessed and shared globally as a service. Most users share the data over the network to make it redundant. However, these resources have some limitations to prevent any kind of network attacks. Many companies are migrating to the cloud for better cost optimization and performance efficiency. The similarity between the contextual quotes is cloud computing are providing resources with cost savings, resilient performance, and constant availability of the data.
In cloud computing, a resource provisioning mechanism is required to supply cloud consumers a set of computing resources for processing the jobs and storing the data. Cloud providers can offer cloud consumers two resource provisioning plans, namely short-term on-demand, and long-term reservation plans. (Chai Siri et al.,2012, p. 164)
I have found this contextual sentence on an article called “Optimization of Resource Provisioning Cost in Cloud Computing”. This quote explains a functional computing requires resource Provisioning which means the selection, deployment, and run-time management of software. Moreover, Hardware provisioning is also required for better performance. Without the provision a service would not function properly, and users cannot compute. To make this work, many users choose short term on demand instances (Virtual computers) to run the programs or batch jobs for schedule system updates, and for long term usage, users choose reserved instances for cheaper cost and effective performance and they can use the instance for 1-3 years.
Working Definition
Based on my analysis and research I can say that cloud computing has made huge impact on organizations. The resources and services help the users to maintain the data and run programs without having the necessity of maintaining the servers and data centers. Thus, Users can choose provisioning plans for better cost optimization and redundant performance.
