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 hardware, computer and networking hardware and facilities), but also various software and Computer network, 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 ...

McGraw Hill was sold in 2021 to Platinum Equity for $4.5 billion. History McGraw Hill was founded in 1888, when James H. McGraw, co-founder of McGraw Hill, purchased the ''American Journal of Railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software-defined Infrastructure
Software-defined infrastructure (SDI) is the definition of technical infrastructure controlled by computer hardware, that is entirely under the control of software. It operates independent of any hardware-specific dependencies and is programmatically extensible. Drive for innovation boosts demand for software-defined equipment. In the SDI approach, an application's infrastructure requirements are defined declaratively (both functional and non-functional requirements). The hardware features enough versatility to control the infrastructure, and the software defines the functionalities, than can be changed by simply replacing the software. Another approach to software defined systems are software defined equipment (SDE) or software defined apparatus (SDA) Typical uses of software defined equipment are: * Software defined radio * Software defined network * Software defined television In embedded design, the role of software defined equipment or apparatus (SDE/SDA) can be defined b ...

Infrastructure As A Service
Infrastructure as a service (IaaS) is a cloud computing service model where a cloud services vendor provides computing resources such as storage, network, servers, and virtualization (which emulates computer hardware). This service frees users from maintaining their own data center, but they must install and maintain the operating system and application software. Iaas provides users high-level APIs to control details of underlying network infrastructure such as backup, data partitioning, scaling, security and physical computing resources. Services can be scaled on-demand by the user. According to the Internet Engineering Task Force (IETF), such infrastructure is the most basic cloud-service model. IaaS can be hosted in a public cloud (where users share hardware, storage, and network devices), a private cloud (users do not share resources), or a hybrid cloud (combination of both). Overview The US National Institute of Standards and Technology (NIST) defines infrastructure as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Event Management (ITIL)
Event Management, as defined by ITIL, is the process that monitors all events that occur through the IT infrastructure. It allows for normal operation, detecting changes of state and escalating exception events and other priorities. An event can be defined as any detectable or discernible occurrence that has significance for the management of the IT Infrastructure or the delivery of IT service and evaluation of the impact a deviation might cause to the services. Events are typically notifications created by an IT service, Configuration Item (CI) or monitoring tool. Purpose/scope * The purpose is the ability to detect events, investigate and determine the correct control action * The events (warnings and exceptions) can be used to automate many routine activities * Event Management can be applied to any aspects of Service Management that can be controlled and can be automated (Configuration Items) * Provide mechanisms for early detection of incidents. * Some types of automated ac ...

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. Design Hyperconvergence evolves away from discrete, software-defined systems that are connected and packaged together toward a purely softw ...

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 ...

Cyber Infrastructure
United States federal government agencies 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 federal laboratories, large scales of data, processing power, and scientists with the goal of enabling novel scientific discoveries and advancements in human 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 n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
