Architectural Domain
An architecture domain in enterprise architecture is a broad view of an enterprise or system. It is a partial representation of a whole system that addresses several concerns of several stakeholders. It is a description that hides other views or facets of the system described. Business, data, application and technology architectures are recognized as the core domains in the most of proposed concepts concerned with the definition of enterprise architecture. Overview Since Stephen Spewak's book called enterprise architecture planning (EAP) in 1993, and perhaps before then, it has been normal to recognise four types of architecture domain. The British Computer Society's "Reference Model for Enterprise and Solution Architecture" also follows this subdivision but additionally mentions the (single) application architecture level just below the application''s'' architecture as well as the domains of information architecture, information systems architecture, or security architectur ...

Structure Of The FEAF Components
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, anthills, beaver dams, bridges and salt domes are all examples of load-bearing structures. The results of construction are divided into buildings and non-building structures, and make up the infrastructure of a human society. Built structures are broadly divided by their varying design approaches and standards, into categories including building structures, archi ...

Security Architecture
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution ...

TOGAF
The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture as of 2020 that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. TOGAF is a high-level approach to design. It is typically modeled at four levels: Business, Application, Data, and Technology. It relies heavily on modularization, standardization, and already existing, proven technologies and products. TOGAF was developed starting 1995 by The Open Group, based on United States Department of Defense's TAFIM and Capgemini's Integrated Architecture Framework (IAF). As of 2016, The Open Group claims that TOGAF is employed by 80% of Global 50 companies and 60% of Fortune 500 companies. Overview An architecture framework is a set of tools which can be used for developing a broad range of different architectures. It should: * describe a method for defining an information system in terms of a set of buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solution Architecture
Solution architecture, term used in information technology with various definitions such as; "A description of a discrete and focused business operation or activity and how IS/ IT supports that operation". Definitions The Open Group's definition of Solution Architecture, as provided above, is accompanied by the following three from Scaled Agile, Gartner and Greefhorst/Proper. It is worth noting that the Open Group does not recognize the role "Solution Architect" in its TOGAF skills framework whilst Glassdoor advertised 55,000 Solution Architect roles in August 2020. * Scaled agile (2020) ''Solution Architect/Engineering is responsible for defining and communicating a shared technical and architectural vision across a "Solution Train" to help ensure the system or Solution under development is fit for its intended purpose.'' * Gartner (2013) ''A solution architecture (SA) is an architectural description of a specific solution. SAs combine guidance from different enterprise archit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterprise Architecture Framework
An enterprise architecture framework (EA framework) defines how to create and use an enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system. It structures architects' thinking by dividing the architecture description into domains, layers, or views, and offers models - typically matrices and diagrams - for documenting each view. This allows for making systemic design decisions on all the components of the system and making long-term decisions around new design requirements, sustainability, and support. Overview Enterprise architecture regards the enterprise as a large and complex system or system of systems. To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description doc ...

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 organi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Technology Architecture
Information technology architecture is the process of development of methodical information technology specifications, models and guidelines, using a variety of information technology notations, for example Unified Modeling Language (UML), within a coherent information technology architecture framework, following formal and informal information technology solution, enterprise, and infrastructure architecture processes. These processes have been developed in the past few decades in response to the requirement for a coherent, consistent approach to delivery of information technology capabilities. They have been developed by information technology product vendors and independent consultancies, such as for example the Open Group, based on real experiences in the information technology marketplace and collaboration amongst industry stakeholders. Best practice information technology architecture encourages the use of open technology standards and global technology interoperability. Infor ...

Software Architecture
Software architecture is the fundamental structure of a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. The ''architecture'' of a software system is a metaphor, analogous to the architecture of a building. It functions as a blueprint for the system and the developing project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved. Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. For example, the systems that controlled the Space Shuttle launch vehicle had the requirement of being very fast and very reliable. Therefore, an appropriate real-time computing language would need to be chosen. Additiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
