Cloud computing in the context of Cloud storage

Cloud gaming, sometimes called gaming on demand or game streaming, is a type of online gaming that runs video games on remote servers and streams the game's output (video, sound, etc.) directly to a user's device, or more colloquially, playing a game remotely from a cloud. It contrasts with traditional means of gaming, wherein a game is run locally on a user's video game console, personal computer, or mobile device.

Google LLC (/ˈɡuː.ɡəl/ , GOO-gəl) is an American multinational technology corporation focused on information technology, online advertising, search engine technology, email, cloud computing, software, quantum computing, e-commerce, consumer electronics, and artificial intelligence (AI). It has been referred to as "the most powerful company in the world" by the BBC, and is one of the world's most valuable brands. Google's parent company Alphabet Inc. has been described as a Big Tech company.

Google was founded on September 4, 1998, by American computer scientists Larry Page and Sergey Brin. Together, they own about 14% of its publicly listed shares and control 56% of its stockholder voting power through super-voting stock. The company went public via an initial public offering (IPO) in 2004. In 2015, Google was reorganized as a wholly owned subsidiary of Alphabet Inc. Google is Alphabet's largest subsidiary and is a holding company for Alphabet's internet properties and interests. Sundar Pichai was appointed CEO of Google on October 24, 2015, replacing Larry Page, who became the CEO of Alphabet. On December 3, 2019, Pichai also became the CEO of Alphabet.

Microsoft Corporation is an American multinational technology conglomerate headquartered in Redmond, Washington. Founded in 1975, the company became influential in the rise of personal computers through software like Windows, and has since expanded to Internet services, cloud computing, artificial intelligence, video gaming, and other fields. Often described as a Big Tech company, Microsoft is the largest software company by revenue, one of the most valuable public companies, and one of the most valuable brands globally.

Microsoft was founded by Bill Gates and Paul Allen to market BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Windows. During the 41 years from 1980 to 2021 Microsoft released 9 versions of MS-DOS with a median frequency of 2 years, and 13 versions of Windows with a median frequency of 3 years. The company's 1986 initial public offering (IPO) and subsequent rise in its share price created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market. Steve Ballmer replaced Gates as CEO in 2000. He oversaw the then-largest of Microsoft's corporate acquisitions in Skype Technologies in 2011, an increased focus on hardware that led to its first in-house PC line, the Surface, in 2012, and the formation of Microsoft Mobile through Nokia. Since Satya Nadella took over as CEO in 2014, the company has changed focus towards cloud computing, as well as its acquisition of LinkedIn for $26.2 billion in 2016. Under Nadella's direction, the company has expanded its video gaming business to support the Xbox brand, establishing the Microsoft Gaming division in 2022 and the acquisition of Activision Blizzard for $68.7 billion in 2023.

Amazon.com, Inc., doing business as Amazon, is an American multinational technology company engaged in e-commerce, cloud computing, online advertising, digital streaming, and artificial intelligence. Founded in 1994 by Jeff Bezos in Bellevue, Washington, the company originally started as an online marketplace for books, but gradually expanded its offerings to include a wide range of product categories, referred to as "The Everything Store". Amazon has been described as a Big Tech company.

The company has multiple subsidiaries, including Amazon Web Services (or AWS), providing cloud computing; Zoox, a self-driving car division; Kuiper Systems, a satellite Internet provider; and Amazon Lab126, a computer hardware R&D provider. Other subsidiaries include Ring, Twitch, IMDb, and Whole Foods Market. Its acquisition of Whole Foods in August 2017 for US$13.4 billion substantially increased its market share and presence as a physical retailer. Amazon also distributes a variety of downloadable and streaming content through its Amazon Prime Video, MGM+, Amazon Music, Twitch, Audible and Wondery units. It publishes books through its publishing arm, Amazon Publishing, produces and distributes film and television content through Amazon MGM Studios, including the Metro-Goldwyn-Mayer studio it acquired in March 2022, and owns Brilliance Audio and Audible, which produce and distribute audiobooks, respectively. Amazon also produces consumer electronics—most notably, Kindle e-readers, Echo devices, Fire tablets, and Fire TVs.

A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The newest manifestation of cluster computing is cloud computing.

The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware.

Enterprise resource planning (ERP) is the integrated management of main business processes, often in real time and mediated by software and technology. ERP is usually referred to as a category of business management software—typically a suite of integrated applications—that an organization can use to collect, store, manage and interpret data from many business activities. ERP systems can be local-based or cloud-based. Cloud-based applications have grown rapidly since the early 2010s due to the increased efficiencies arising from information being readily available from any location with Internet access. However, ERP differs from integrated business management systems by including planning all resources that are required in the future to meet business objectives. This includes plans for getting suitable staff and manufacturing capabilities for future needs.

ERP provides an integrated and continuously updated view of core business processes, typically using a shared database managed by a database management system. ERP systems track business resources—cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across various departments (manufacturing, purchasing, sales, accounting, etc.) that provide the data. ERP facilitates information flow between all business functions and manages connections to outside stakeholders.

ChromeOS (sometimes styled as chromeOS and formerly styled as Chrome OS) is an operating system designed and developed by Google. It is derived from the open-source ChromiumOS operating system (which itself is derived from Gentoo Linux), and uses the Google Chrome web browser as its principal user interface.

Google announced the project in July 2009, initially describing it as an operating system where applications and user data would reside in the cloud. ChromeOS was used primarily to run web applications.

Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as packet loss, bit rate, throughput, transmission delay, availability, jitter, etc.

In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.

Video capture is the process of converting an incoming digital or analog video signal (and accompanying audio)—such as that produced by a video camera, or any other video source—for the purposes of using a computer, the cloud, content delivery network or AI servers to process, broadcast, provide image recognition, or otherwise share the captured video.

The earliest 16-bit ISA capture cards emerged in the early 90s. These cards were supported by VIDCAP as part of the Video for Windows package. One early card was a sandwich of two cards as early processors needed more logic to even get up to 15 frames per second (fps).

Remote work (also called telecommuting, telework, work from or at home, WFH as an initialism, hybrid work, and other terms) is the practice of working at or from one's home or another space rather than from an office or workplace.

The practice of working at home has been documented for centuries, but remote work for large employers began on a small scale in the 1970s, when technology was developed that could link satellite offices to downtown mainframes through dumb terminals using telephone lines as a network bridge. It became more common in the 1990s and 2000s, facilitated by internet technologies such as collaborative software on cloud computing and conference calling via videotelephony. In 2020, workplace hazard controls for COVID-19 catalyzed a rapid transition to remote work for white-collar workers around the world, which largely persisted even after restrictions were lifted.

A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems.

Since IT operations are crucial for business continuity, a data center generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., cooling, fire suppression), and various security devices. Data centers are the foundation of the digital infrastructure that powers the modern economy, aggregating collective computing demands for cloud services, video streaming, blockchain and crypto mining, machine learning, and virtual reality. Large data centers operate at an industrial scale, requiring significant energy. Estimated global data center electricity consumption in 2024 was around 415 terawatt hours (TWh), or about 1.5% of global electricity demand. The IEA projects that data center electricity consumption could double by 2030. High demand, driven by artificial intelligence (AI) and machine learning workloads is accelerating the deployment of high-performance servers, leading to greater power density and increased strain on electric grids.

A computer system resource is any hardware or software aspect of limited availability that is accessible to a computer system. Like any resource, computer system resources can be exhausted, and issues arise due to scarcity.

Resource management, a key aspect of designing hardware and software, includes preventing resource leaks (not releasing a resource done with it) and handling resource contention (when multiple processes want to access the same resource). Computing resources are used in cloud computing to provide services through networks.

Digital goods or e-goods are intangible goods that exist in digital form. Examples are Wikipedia articles; digital media, such as e-books, downloadable music, internet radio, internet television and streaming media; fonts, logos, photos and graphics; digital subscriptions; online ads (as purchased by the advertiser); internet coupons; electronic tickets; electronically treated documentation in many different fields; downloadable software (Digital Distribution) and mobile apps; cloud-based applications and online games; virtual goods used within the virtual economies of online games and communities; community access; workbooks; worksheets; planners; e-learning (online courses); webinars, video tutorials, blog posts; cards; patterns; website themes and templates.
