Other Definitions

  • Gartner IT Glossary (†298 s.v. public cloud computing): A style of computing where scalable and elastic IT-enabled capabilities are provided as a service to external customers using Internet technologies – i.e., public cloud computing uses cloud computing technologies to support customers that are external to the provider’s organization. Using public cloud services generates the types of economies of scale and sharing of resources that can reduce costs and increase choices of technologies. From a government organization’s perspective, using public cloud services implies that any organization (in any industry sector and jurisdiction) can use the same services (e.g., infrastructure, platform or software), without guarantees about where data would be located and stored.
  • Mell and Grance 2011 (†334 p. 3): The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider.

  • Duranti 2013 (†408 ): Public Cloud infrastructure is made available to the general public over the Internet. By definition external to the customers’ organization, public clouds are owned and operated by third-party providers, and usage is subject to detailed service level agreements. (†483)
  • Evans 2013B (†340 ): Myth #1: Public cloud is the only true cloud. While public clouds continue to garner more notoriety than private clouds – particularly among the media and capital markets – the truth of the matter is that the volume of private cloud adoptions still exceeds that of public cloud adoption (†321)
  • Evans 2013B (†340 ): Myth #8: Public clouds are still not secure. Security has long been one of top concerns among organizations considering a move to public clouds. The fact is that businesses often improve application and data security by leveraging enterprise-grade public clouds. Many corporate data centers have limited security resources and expertise, challenges meeting regulatory requirements, outdated software and hardware, and don't perform regular security audits and assessments. On the other hand, tight security is table stakes for any public cloud provider as many have the following: · a dedicated team of cloud security experts, · processes that ensure full compliance with regulatory, and industry standards, · regularly scheduled third-party security audits, and, · automatic updates for their hardware and software. Still, not all cloud security is equal and the best advice is to review your cloud provider's security technology and practices to understand any potential security risks. (†323)
  • Furht and Escalante 2010 (†583 p.7): In the public cloud (or external cloud) computing resources are dynamically provisioned over the Internet via Web applications or Web services from an off-site third-party provider. Public clouds are run by third parties, and applications from different customers are likely to be mixed together on the cloud’s servers, storage systems, and networks. (†1202)

  • McLelland, et al. 2014 (†403 7): The first possible implementation is a “public” cloud. Here the word “public” does not refer to government agencies but rather to an infrastructure that is shared by all clients of a service provider. In this public cloud, all clients’ information is stored together, with only logical separations to distinguish one from the other. This form of cloud service is commonly accessed remotely.

  • Seagate 2017 (†881 ): a public cloud is something like Dropbox or Google Drive or Box or any other model where a service provider makes online resources like software and data storage available through the Internet. Cloud services are provided using a virtualised ecosystem, and constructed using pooled, shared physical resources. In many cases, an individual or organisation has little control over the ecosystem in which the online cloud is hosted as the infrastructure is shared and built by many individuals across many organisations. Data and applications on online clouds are separated so that only authorised users may access certain subsets as appropriate. (†2662)
  • Stancic, Rajg, and Milosevic 2013 (†904 p. 111): The cloud infrastructure is intended for “rent” by the public users, as delegated by the provider usually for profit or other means of compensation for the provider. (†2723)
  • Wikipedia (†387 s.v. "Cloud computing"): A cloud is called a "public cloud" when the services are rendered over a network that is open for public use. Technically there may be little or no difference between public and private cloud architecture, however, security consideration may be substantially different for services (applications, storage, and other resources) that are made available by a service provider for a public audience and when communication is effected over a non-trusted network. Generally, public cloud service providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access only via Internet (direct connectivity is not offered).[41] (†433)
