"A model for network access in which large, scalable resources are provided via the Internet as a shared service to requesting users. Access, computing, and storage services can be obtained by users without the need to understand or control the location and configuration of the system. Users consume resources as a service, and pay only for the resources that are used." (Jim Davis & Aiman Zeid, "Business Transformation: A Roadmap for Maximizing Organizational Insights", 2014)
"The delivery of software and other computer resources as a service over the Internet, rather than as a stand-alone product." (Manish Agrawal, "Information Security and IT Risk Management", 2014)
"The provision of computational resources on demand via a network. Cloud computing can be compared to the supply of electricity and gas or the provision of telephone, television, and postal services. All of these services are presented to users in a simple way that is easy to understand without users' needing to know how the services are provided. This simplified view is called an abstraction. Similarly, cloud computing offers computer application developers and users an abstract view of services, which simplifies and ignores much of the details and inner workings. A provider's offering of abstracted Internet services is often called the cloud." (Robert F Smallwood, "Information Governance: Concepts, Strategies, and Best Practices", 2014)
"A computational paradigm that aims at supporting large-scale, high-performance computing in distributed environments via innovative metaphors such as resource virtualization and de-location." (Alfredo Cuzzocrea & Mohamed M Gaber, "Data Science and Distributed Intelligence", 2015)

"A delivery model for information technology resources and services that uses the Internet to provide immediately scalable and rapidly provisioned resources as services using a subscription or utility-based fee structure." (James R Kalyvas & Michael R Overly, "Big Data: A Businessand Legal Guide", 2015)
"A service that provides storage space and other resources on the Internet" (Nell Dale & John Lewis, "Computer Science Illuminated, 6th Ed.", 2015)
"Delivering hosted services over the Internet, which includes providing infrastructures, platforms, and software as services." (Mike Harwood, "Internet Security: How to Defend Against Attackers on the Web 2nd Ed.", 2015)
"The delivery of computer processing capabilities as a service rather than as a product, whereby shared resources, software, and information are provided to end users as a utility. Offerings are usually bundled as an infrastructure, platform, or software." (Adam Gordon, "Official (ISC)2 Guide to the CISSP CBK" 4th Ed., 2015)
"A general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS), and Analytics-as-a-Service (AaaS)." (Suren Behari, "Data Science and Big Data Analytics in Financial Services: A Case Study", 2016)
"A type of Internet-based technology in which different services (such as servers, storage, and applications) are delivered to an organization’s or an individual’s computers and devices through the Internet." (Jonathan Ferrar et al, "The Power of People: Learn How Successful Organizations Use Workforce Analytics To Improve Business Performance", 2017)
"A form of distributed computing whereby many computers and applications share the same resources to work together, often across geographically separated areas, to provide a coherent service." (O Sami Saydjari, "Engineering Trustworthy Systems: Get Cybersecurity Design Right the First Time", 2018)
"Cloud computing is a general term for the delivery of hosted services over the Internet. Cloud computing enables companies to consume compute resources as a utility - just like electricity - rather than having to build and maintain computing infrastructures in-house." (Thomas Ochs & Ute A Riemann, "IT Strategy Follows Digitalization", 2018)
"Cloud computing refers to the provision of computational resources on demand via a network. Cloud computing can be compared to the supply of a utility like electricity, water, or gas, or the provision of telephone or television services. All of these services are presented to the users in a simple way that is easy to understand without the users’ needing to know how the services are provided. This simplified view is called an abstraction. Similarly, cloud computing offers computer application developers and users an abstract view of services, which simplifies and ignores many of the details and inner workings. A provider’s offering of abstracted Internet services is often called The Cloud." (Robert F Smallwood, "Information Governance for Healthcare Professionals", 2018)
