Agile Infrastructure
Agile IT infrastructure, or Agile Infrastructure for short, is an emerging type of IT infrastructure that goes beyond Hyper-converged infrastructure and puts emphasis on: * speed of implementing change; * reducing complexity; * resilience; * quick adaptation to new technologies; * taking advantage of lightweight deployment options; * easy accessibility of management tools; and * making everyone hero A hero (feminine: heroine) is a real person or fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or Physical strength, strength.

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 ...

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 ...

Change Management
Change management (CM) is a discipline that focuses on managing changes within an organization. Change management involves implementing approaches to prepare and support individuals, teams, and leaders in making organizational change. Change management is useful when organizations are considering major changes such as restructure, redirecting or redefining resources, updating or refining business process and systems, or introducing or updating digital technology. Organizational change management (OCM) considers the full organization and what needs to change, while change management may be used solely to refer to how people and teams are affected by such organizational transition. It deals with many different disciplines, from behavioral and social sciences to information technology and business solutions. As change management becomes more necessary in the business cycle of organizations, it is beginning to be taught as its own academic discipline at universities. There are a gro ...

Complexity
Complexity characterizes the behavior of a system or model whose components interact in multiple ways and follow local rules, leading to non-linearity, randomness, collective dynamics, hierarchy, and emergence. The term is generally used to characterize something with many parts where those parts interact with each other in multiple ways, culminating in a higher order of emergence greater than the sum of its parts. The study of these complex linkages at various scales is the main goal of complex systems theory. The intuitive criterion of complexity can be formulated as follows: a system would be more complex if more parts could be distinguished, and if more connections between them existed. , a number of approaches to characterizing complexity have been used in science; Zayed ''et al.'' reflect many of these. Neil Johnson states that "even among scientists, there is no unique definition of complexity – and the scientific notion has traditionally been conveyed using partic ...

Resilience (network)
High availability (HA) is a characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period. There is now more dependence on these systems as a result of modernization. For example, to carry out their regular daily tasks, hospitals and data centers need their systems to be highly available. Availability refers to the ability of the user to access a service or system, whether to submit new work, update or modify existing work, or retrieve the results of previous work. If a user cannot access the system, it is considered ''unavailable from the user's perspective''. The term ''downtime'' is generally used to refer to describe periods when a system is unavailable. Resilience High availability is a property of network resilience, the ability to "provide and maintain an acceptable level of service in the face of faults and challenges to normal operation." Threats and challenges for services can range from sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptation
In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each individual organism, that is maintained and has evolved through natural selection. Historically, adaptation has been described from the time of the ancient Greek philosophers such as Empedocles and Aristotle. In 18th and 19th-century natural theology, adaptation was taken as evidence for the existence of a deity. Charles Darwin and Alfred Russel Wallace proposed instead that it was explained by natural selection. Adaptation is related to biological fitness, which governs the rate of evolution as measured by changes in allele frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hero
A hero (feminine: heroine) is a real person or fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or Physical strength, strength. The original hero type of classical epics did such things for the sake of glory (honor), glory and honor. post-classical history, Post-classical and modern history, modern heroes, on the other hand, perform great deeds or selfless acts for the common good instead of the classical goal of wealth, pride, and fame. The antonym of ''hero'' is ''villain''. Other terms associated with the concept of ''hero'' may include ''good guy'' or ''wikt:white hat, white hat''. In Classics, classical literature, the hero is the main or revered character in Epic poetry, heroic epic poetry celebrated through ancient legends of a people, often striving for military conquest and living by a continually flawed personal honor code. The definition of a hero has changed throughout time. Webster's Dictionary, Merriam We ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computing Platforms
A computing platform, digital platform, or software platform is the infrastructure on which software is executed. While the individual components of a computing platform may be obfuscated under layers of abstraction, the ''summation of the required components comprise the computing platform''. Sometimes, the most relevant layer for a specific software is called a computing platform in itself to facilitate the communication, referring to the whole using only one of its attributes – i.e. using a metonymy. For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. In the case of an application program or a computer video game, the most relevant layer is the operating system, so it can be called a platform itself (hence the term cross-platform for software that can be executed on multiple OSes, in this context). In a multi-computer system, such as in the case of offloading processing, it would encompass bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
