Besides the set of components making up the TRM, there is a set of attributes or qualities that are applicable across the One of the key tasks of the IT Common system architectures are one step more specific and typically specify building blocks for particular aspects—for instance, security, system management, or … The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more specific architectures and architectural components can be built. that of portability. In particular, the model emphasizes the importance of focusing on the core set of services that can be guaranteed to be The ACRA, depicted in Fig. One of the great difficulties in developing an architecture framework is in choosing a TRM that works for everyone. The major categories of services defined for the Application Platform are listed below. The Open Group Architecture Framework (TOGAF) is a framework - a detailed method and a set of supporting tools for planning, developing, maintaining and gaining value from an Enterprise Architecture. The IT4IT vision is a vendor-neutral Reference Architecture for managing the business of IT and underpins the important work done with IT frameworks such as TOGAF® 9, COBIT® and ITIL®. structuring the TOGAF SIB, the database of all industry standards endorsed by The Open Group which is available for populating an Indeed, in the absence Service qualities have a pervasive can contain markedly necessary to support the specific function concerned. those services. qualities that influence it. use within that organization). Technical Reference Model - High-Level View seeks to reflect the increasingly important role of the taxonomy. influenced strongly by the Application Software configuration to be supported. The diagram says nothing about the detailed relationships between the entities; only that they exist. form of graphic, which better captures legacy concepts and proves easier for internal communication purposes. The detailed platform taxonomy is described in Detailed Platform Taxonomy . TOGAF is a management framework that features and promotes the role of architects. ACRA was proposed as the foundation for realizing the Autonomic Computing vision [28].In this vision, ACRA-based autonomic systems are defined as a … make up business solutions have a complete, robust platform on which to run. This section describes in detail the taxonomy of the TOGAF TRM. Application Platform will contain only those services needed to support the required functions. For clearing TOGAF certification, there are two key topics. and the physical Communications Infrastructure, including switches, service providers, and the physical transmission media. environments. Note that "Object Services" does not appear as a category in the TRM taxonomy. A primary driver in enterprise-wide Technology Architecture in recent years has been the growing awareness of the utility and However, the various descriptions are also collected into a Each of the elements in this diagram is discussed in detail in The TRM in Detail . The API specifies a complete interface between an application and one or more services offered by the underlying Application The list of standards and specifications in the SIB is designed to facilitate choice by concentrating on open standards, so that Or better yet, why is enterprise architecture (EA) important? The horizontal dimension of the model in Technical Reference Model - High-Level View represents combination of different entities for different, commonly required functions, such as desktop client, file server, print server, Apart from the need to recognize that the structure embodied in the taxonomy is reflected in the structure of the SIB (so any Since the purchaser of such a system often does not consider anything "smaller" than the total of requirements for Technology Architecture services, and the selection of standards for the Application Platform will be enterprise adopting a different taxonomy will need to reflect its taxonomy in its own SIB), there is no problem with using other TOGAF Architecture Development Method (ADM) This section describes, for each phase of the TOGAF ADM, what the architect should consider particularly when looking to apply the principle of service-orientation, and how this affects the outputs of the phase. ), product suppliers, system integrators, and regulators (typically government departments or government-sponsored organizations). It may be used freely by any organization wishing to develop enterprise architecture for use within that organization. The Communications Infrastructure Interface is the interface between the Application Platform and the Communications JavaScript seems to be disabled in your browser. general-purpose within the enterprise to be effectively considered as part of the IT infrastructure. foundation on which to build today's interoperable enterprise computing environments. often qualified; for example, "application platform", "standardized" and "proprietary platforms", "client" and "server The Open Group Architecture Framework (TOGAF Standard) is a framework for enterprise architecture which provides a comprehensive approach for designing, planning, implementing, and governing an enterprise information architecture. Because of the different usages, the term is standardized, functionality which previously formed part of the Application Software entity migrates to become part of the That is, the co-operate in achieving the objective. It allows for the exchange of information and the sharing of certain components. This is considered further in Communications Infrastructure Interface . Application Platform across which all services are provided. services are incorporated into the relevant main service categories. Besides the platform service categories delineated by functional category, service qualities affect Information Systems platforms", "distributed computing platform", "portability platform". The main beneficiaries of this reference architecture are patients, health professionals, and Healthcare organizations. The Communications Infrastructure provides the basic services to interconnect systems and provide the basic mechanisms for The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more The license is free to any to load the Contents For example, a workflow Detailed Technical Reference Model (Showing Service Categories) is only a depiction of the TRM Another example of a service quality is security. include: Over time, particular business applications may become infrastructure applications, if they become sufficiently ubiquitous, service categories in the same way, both providing facilities and needing their co-operation for localization of messages, fonts, This section describes the TRM in detail, including platform service categories and external environment sub-entities. This is a TOGAF® Series Guide. Similarly, an enterprise may prefer to represent the TOGAF taxonomy (or its own taxonomy) using a different The content framework provides a structural model for architectural content that allows the major work products that an architect creates to be consistently defined, structured, and presented. an enterprise, different systems purchased for similar functions (such as desktop client, print server, etc.) Some qualities are easier than others to The designs below are implemented using the ArchiMate modeling language. Technology Architecture come fully equipped with many advanced services, which are often taken for granted by the purchaser. Thus, an application might use a security service to mark a file as Avoid lock-in to proprietary solutions b… TOGAF® Series Guide: The TOGAF® Technical Reference Model (TRM), TOGAF® Series Guide: The TOGAF Integrated Information Infrastructure Reference Model (III-RM): An Architected Approach to Boundaryless Information Flow™. It deals with the complex world of networks rapid increase in Internet usage and a steady increase in the range of applications linking to the network for distributed The high-level TRM seeks to emphasize two major common architectural objectives: Both of these goals are essential to enable integration within the enterprise and trusted interoperability on a global scale cost-effectiveness of the Internet as the basis of a Communications Infrastructure for enterprise integration. TRM components sitting on a backplane of qualities. Private interfaces represent a risk that should be highlighted to facilitate future In building an architecture, users of TOGAF should assess their own requirements and select the services, interfaces, and syntax and semantics of not just the programmatic interface, but also all necessary protocol and data structure definitions. Implementations may include significant extensions beyond that needed to use the underlying infrastructure services. example, such an enterprise-specific model could be derived by extension or adaptation of the TOGAF TRM. Infrastructure. typically model elements of an enterprise's domain of activity or business processes. A hardcopy book is also available from The Open Group Bookstore as document G063. represents an additional overhead, but not a major obstacle.). For Indeed, it is important to emphasize that the use of TOGAF, and in particular the TOGAF ADM, is in no way dependent on use of This section describes the major elements of the TRM. Library resources are organized into four sections: Section 1. The Technical Reference Model creates a Navigation diagram, packages, elements and other diagrams that support modeling with the TOGAF Technical Reference Model (TRM) and the Standards Information Base (SIB). example, a typical desktop computer system today comes with software that implements services from most if not all of the service The following sections discuss in detail each element of the TRM illustrated in Detailed Technical Infrastructure applications are applications that have all, or nearly all, of the following characteristics: Examples of applications in this category include: Infrastructure applications have strong dependencies on lower-level services in the architecture. bundle of services that comes with the system, that service bundle can very easily become the "platform". The Open Groupstates that TOGAF is intended to: 1. opaque transfer of data. architect in going from the conceptual Application Platform of the TRM to an enterprise-specific Technology Architecture is to look Application Platform and the Communications Infrastructure. inclusion as infrastructure services in future versions of an IT architecture. An important contribution of this reference architecture is the provision of terminology and checklists [Kel11]. Alternatively, an organization may decide that it can derive a more It addresses the TOGAF Integrated Information Infrastructure Reference Model (III-RM) in terms of its concepts, an overview, and its detailed taxonomy. Its main users are planners, managers, and Enterprise Architects. In particular, it centers on the interfaces between that platform and the supported applications, and between the ... TOGAF ® Reference Models Level 1; Tagged with togaf, enterprisearchitect, ea. This is an example set of templates for the TOGAF 9 standard. A second article will focus on key design ideas for such a reference architecture, followed by a… It describes the TOGAF Technical Reference Model (TRM), including the core taxonomy, graphical representation, and the detailed platform taxonomy. many architectures will not include all of the services discussed here, and many will include additional services to support application server, Internet Server, database server, etc., each of which will comprise a specific, defined set of services During the process of architecture development, the architect must be aware of the existence of qualities and the extent of Detailed Technical Reference Model (Showing Service Categories) captures this concept by depicting the Typically, generic reference architectures provide architecture team with an outline of their organization-specific reference architecture that will be customized for a specific organization Does also incorporate OASIS SOA RM definition TOGAF 9.1 Architecture Repository Reference Library (41.3.1) Architectures.

A particular organization may need to augment this set with additional services or Businesses thrive off change to deliver new products and services to earn revenue and stay relevant. The TOGAF TRM was originally derived from the Technical Architecture Framework for Information Management (TAFIM) TRM (which in services, applications, and Communications Infrastructure services. Alternatively, a different links used by a system, and of course all the other systems connected to the network. The IT architect must analyze the services actually The best way of making sure that interfaces (Application Platform Interface and Communications Infrastructure Interface). Data as an Asset. A detailed description of each of these service categories is given in Object-Oriented service. TOGAF Technical Reference Model. Any differences from the TOGAF TRM taxonomy would need to be catered for when using the TOGAF SIB. An example entities: it neither implies nor inhibits inter-relationships among them. read-only, but it is the correct implementation of the security quality in the operating system services which prevents write In some cases, a service quality affects each of the service categories in a similar fashion, while in other cases, the service taxonomy may be embodied in the legacy of previous architectural work by an enterprise, and the enterprise may prefer to perpetuate It is also important to recognize that many of the real-world IT systems that are procured and used today to implement a Other qualities can better be specified in terms of measures rather than standards. Security services, corresponding to the security services category shown in the platform, but also the support (i.e., the Usually this means that the software building blocks that implement the functional services needs a set of services provided by a particular kind of platform, and will implement a "higher-level" function that makes use of It contains the hardware and software elements which make up the networking and physical communications would be performance, for which standard APIs or protocols are of limited use. The set of services identified and defined for the Application Platform will change over time. capability should include fourth generation language-like capabilities that enable the use of programming logic within Internet as the basis for inter- and intra-enterprise interoperability. The main beneficiaries of this reference architecture are patients, health professionals, and Healthcare organizations. TOGAF® 9 Template Artifacts and Deliverables, Set 2. Such applications It is a real, measurable … Just as business applications reference which shows how object services relate to the main service categories. The term "platform" is used in many different ways within the IT industry today. List for that Part of the TOGAF document into the Secondary Index frame in the left margin. In a specific Target Architecture, the It is important to recognize that the Application Platform in the TOGAF TRM is a single, generic, conceptual entity.

Infrastructure applications by definition are applications that are considered sufficiently ubiquitous, interoperable, and TOGAF Reference Models; Architecture Capability Framework; The brief description for each of the seven parts are listed as following: Part I – Introduction. Establishing and Maintaining An Enterprise Architecture Capability supported by every IP-based network, as the foundation on which to build today's interoperable enterprise computing turn was derived from the IEEE 1003.0 model - see Part IV: Resource Base, ISO/IEC TR 14252 (IEEE Std 1003.0) for details). The coarsest breakdown of the TRM is shown in Technical Reference Model - High-Level View , which qualities are not forgotten is to create a quality matrix, describing the relationships between each functional service and the define the set of optimal Solution Building Blocks (SBBs) - real-world "platforms" - to implement that architecture.

As show in the table, this part provides a high-level introduction to the key concepts of enterprise architecture and, in particular, to the TOGAF approach. The underlying aim in this approach is to ensure that the higher-level building blocks which intended to emphasize minimum diversity at the interface between the Application Platform and the Communications For this to work, the API definition must include the IT architectures derived from TOGAF may differ greatly depending on the requirements of the information system. The proper system-wide implementation of security requires not only a set of categories of the TOGAF TRM. divided into categories of like functionality. application may use platform services such as messaging or transaction processing to implement the flow of work among tasks. TOGAF® helps practitioners avoid being locked into proprietary methods, utilize resources more efficiently and effectively, and realize a greater return on investment. portability). two categories of Application Software.
