- Cloud. In informational technology, a shared pool of configurable computing resources (both hardware and software, e.g., networks, servers, storage, applications, and services) that are located at a remote physical location managed by an Internet hosting provider or a vendor rather than on the client's premises.
- Public cloud. 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.
- Private cloud. The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.
- Hybrid cloud. The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

- Internet. The largest network of interconnected computing devices that use the Internet protocol suite, TCP/IP, to link the devices globally.
- Mobile app (mobile application or, simply, an app) is an end-user application that is designed to run on a mobile device. Mobile apps often stand in contrast to web applications which run in mobile web browsers rather than directly on the mobile device. Mobile apps often refer those applications as web versions.
- World Wide Web (WWW, www). The part of the Internet that contains inter-linked hypertext documents, especially webpages, and web applications. The web resources are identified by Uniform Resource Locators (URLs) and accessible via the web browsers. The other parts of the Internet include email, VoIP telephony, and file exchange.
- Web browser. Any end-user application that allows for browsing web documents published at the World Wide Web. To request the Browser display some website, a user enters into the Browser the website's hostname. Then, the Browser utilizes DNS to locate the sought website in the World Wide Web and to get its landing page's web document in order to display this webpage in the Browser.
- URL. The acronym for Uniform Resource Locator. A reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. URLs consist of two mandatory fields, (a) type of resource such as
httpsfor webpages,ftpsfor file transfers,mailtofor emails, etc., and (b) hostname, as well as of optional (c) one or more submomains and (d) a file name, if any. - Web search engine (Internet search engine). A software system that is designed to search the World Wide Web for particular information specified in a textual web search query.
- URL. The acronym for Uniform Resource Locator. A reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. URLs consist of two mandatory fields, (a) type of resource such as
- Website. A collection of webpages that are located at the same hostname.
- Landing page. A single webpage that welcomes a visitor to the website to which the Page belongs. The Page casually returns in response to user's clicking on a search result delivered by a web search engine, marketing promotion, marketing email, or an online advertisement, as well as typing the website's hostname into web browser's address bar.
- DNS. The acronym for Domain Name System. Originally created for name mapping, DNS today also defines technical settings for its core mapping service. In addition, DNS is used to set up functionality for the emails using DNS record such as MX and TXT records.
- Hostname (domain name). A humanly readable label or alias that is assigned to a particular IP address or another identification for a host device that is a part of the Internet or another computing network.
- Subdomain (local hostname). In the DNS, a domain that is a part of another domain.

- Single source of truth (SSOT). Either (a) a document which trustfulness is higher that the one of any other document or (b) a database that represents such documents. The concept of SSOT ensures that everyone in an organization bases enterprise decisions on the same data. If some data or document evolves over the time, the SSOT is the practice of working on that data or document in only one place. In database architecture, the SSOT is a model of using a master or federated database as the primary location to propagate any change to the entire system automatically.
