IT Infrastructure
Information technology infrastructure is defined broadly as a set of information technology (IT) components that are the foundation of an IT service; typically physical components (computer and networking hardware and facilities), but also various software and network components. According to the ITIL Foundation Course Glossary, IT Infrastructure can also be termed as “All of the hardware, software, networks, facilities, etc., that are required to develop, test, deliver, monitor, control or support IT services. The term IT infrastructure includes all of the Information Technology but not the associated People, Processes and documentation.” Overview In IT Infrastructure, the above technological components contribute to and drive business functions. Leaders and managers within the IT field are responsible for ensuring that both the physical hardware and software networks and resources are working optimally. IT infrastructure can be looked at as the foundation of an organizati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Hard Drive
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

Dynamic Infrastructure
Dynamic Infrastructure is an information technology concept related to the design of data centers, whereby the underlying hardware and software can respond dynamically and more efficiently to changing levels of demand. In other words, data center assets such as storage and processing power can be provisioned (made available) to meet surges in user's needs. The concept has also been referred to as ''Infrastructure 2.0'' and ''Next Generation Data Center''. Concept The basic premise of dynamic infrastructures is to leverage pooled IT resources to provide flexible IT capacity, enabling the allocation of resources in line with demand from business processes. This is achieved by using server virtualization technology to pool computing resources wherever possible, and allocating these resources on-demand using automated tools. This allows for load balancing and is a more efficient approach than keeping massive computing resources in reserve to run tasks that take place, for example, onc ...

Software-defined Infrastructure
Software-defined infrastructure (SDI) is the definition of technical computing infrastructure entirely under the control of software with no operator or human intervention. It operates independent of any hardware-specific dependencies and is programmatically extensible. In the SDI approach, an application's infrastructure requirements are defined declaratively (both functional and non-functional requirements) such that sufficient and appropriate hardware can be automatically derived and provisioned to deliver those requirements. Typical deployments require software-defined networking (SDN) and cloud computing capabilities as a minimal point of entry. The benefits of SDI is that it lowers/eliminates effort towards infrastructure maintenance, allows companies to move focus to other parts of the software, ensures consistence while also allowing for extensibility, remote deployment through configuration without downtime, and allows you to leverage the power of versioning such as git. ...

Infrastructure As Code
Infrastructure as code (IaC) is the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. The IT infrastructure managed by this process comprises both physical equipment, such as bare-metal servers, as well as virtual machines, and associated configuration resources. The definitions may be in a version control system. The code in the definition files may use either scripts or declarative definitions, rather than maintaining the code through manual processes, but IaC more often employs declarative approaches. Overview IaC grew as a response to the difficulty posed by utility computing and second-generation web frameworks. In 2006, the launch of Amazon Web Services’ Elastic Compute Cloud and the 1.0 version of Ruby on Rails just months before created widespread scaling problems in the enterprise that were previously experienced only at large, multi-nati ...

Infrastructure As A Service
The first major provider of infrastructure as a service (IaaS) was Amazon in 2008. IaaS is a cloud computing service model by means of which computing resources are supplied by a cloud services provider. The IaaS vendor provides the storage, network, servers and virtualization (which mostly refers, in this case, to emulating computer hardware). This service enable users to free themselves from maintaining an on-premise data center. The IaaS provider is hosting these resources in either a public cloud (meaning users share the same hardware, storage, and network devices with other users), private cloud (meaning users does not share these resources), or hybrid cloud (combination of both). It provides the customer with high-level APIs used to dereference various low-level details of underlying network infrastructure like backup, data partitioning, scaling, security, physical computing resources, etc. A hypervisor, such as Xen, Oracle VirtualBox, Oracle VM, KVM, VMware ESX/ESXi, o ...

Information Infrastructure
An information infrastructure is defined by Ole Hanseth (2002) as "a shared, evolving, open, standardized, and heterogeneous installed base" and by Pironti (2006) as all of the people, processes, procedures, tools, facilities, and technology which support the creation, use, transport, storage, and destruction of information. The notion of information infrastructures, introduced in the 1990s and refined during the following decade, has proven quite fruitful to the information systems (IS) field. It changed the perspective from organizations to networks and from systems to infrastructure, allowing for a global and emergent perspective on information systems. Information infrastructure is a technical structure of an organizational form, an analytical perspective or a semantic network. The concept of information infrastructure (II) was introduced in the early 1990s, first as a political initiative (Gore, 1993 & Bangemann, 1994), later as a more specific concept in IS research.

Hyper-converged Infrastructure
Hyper-converged infrastructure (HCI) is a software-defined IT infrastructure that virtualizes all of the elements of conventional " hardware-defined" systems. HCI includes, at a minimum, virtualized computing (a hypervisor), software-defined storage, and virtualized networking (software-defined networking). HCI typically runs on commercial off-the-shelf (COTS) servers. The primary difference between converged infrastructure and hyperconverged infrastructure is that in HCI both the storage area network and the underlying storage abstractions are implemented virtually in software (at or via the hypervisor) rather than physically in hardware. Because software-defined elements are implemented in the context of the hypervisor, management of all resources can be federated (shared) across all instances of a hyper-converged infrastructure. Description Hyperconvergence evolves away from discrete, software-defined systems that are connected and packaged together toward a purely sof ...

Cyber Infrastructure
United States federal research funders use the term cyberinfrastructure to describe research environments that support advanced data acquisition, data storage, data management, data integration, data mining, data visualization and other computing and information processing services distributed over the Internet beyond the scope of a single institution. In scientific usage, cyberinfrastructure is a technological and sociological solution to the problem of efficiently connecting laboratories, data, computers, and people with the goal of enabling derivation of novel scientific theories and knowledge. Origin The term National Information Infrastructure had been popularized by Al Gore in the 1990s. This use of the term "cyberinfrastructure" evolved from the same thinking that produced Presidential Decision Directive NSC-63 on Protecting America's Critical Infrastructures (PDD-63). PDD-63 focuses on the security and vulnerability of the nation's "cyber-based information systems" as we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Technology
Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of Data (computing), data . and information. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a Computer, computer system — including all Computer hardware, hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term ''information technology'' in its modern sense first appeared in a 1958 article published in the ''Harvard Business Review''; authors Harold Leavitt, Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their ...
