Technology Architecture Archimate – The elements of the technological layer are often used to simulate the technological architecture of the company, and describe the structure and behavior of the technological infrastructure of the company.
Figure 82 shows the elements of the technological layer and their conditions. When applicable, the inspiration is shot with the teams of business and application. Some more items will be presented in the next sections.
Technology Architecture Archimate
Note: This indicator does not show all allowable conditions. Each element of the language may have composition, consolidation and specialization conditions with the same type of elements. In addition, there are indirect matters that can be derived as explained in section 5.7.
Raise Model Quality
The most important active structure of the technological layer is the loop. This item is used to model structural devices in this layer. It strictly models the structural side of the system. The behavior is modeled through clear relationships with the behavior.
The technological interface is the (logical) place where technological services offered by the intersection can access other nodes or application layers.
Nodes come in several ways, including unit and system software. The unit simulates the physical calculation resource on which objects can be placed. System software is an infrastructure software component that works on the device. Usually, the knot consists of a number of sub -headings. For example, a device like the server and system program to model the operating system.
The relationship between the components of the technological layer is mainly formed by communication infrastructure. The path models the connection between two or more nodes, through which these nodes can exchange information through. The physical realization of the track is modeled by the connection network. Ie a means of physical communication between two or more devices (or other networks).

Joint represents a settlement or physical resource that hosts, speculation or friction with other calculations or physical resources.
The nodes are elements of active structure that perform technological behavior and appear in the store (or materials, as described technological technological subjects). For example, the nodes of Tegaf frame platforms are used [4] according to.
Nodes can be connected in roads. A node can be assigned to the object to simulate the object lying on the loop.
The objects on the loop can be drawn within or related to the loop in the assignment relationship.
Impact Analysis With Archimate Derived Relationships
The unit presents a physical information resource such as computer programs and objects can be stored or distributed for performance.
The unit is a specialization of a loop that represents a physical information resource with the possibility of treatment. Hardware systems are often used model systems such as mainframes, PCs or routers. Usually they are part of the loop with the system software. Units can be compound; Ie Consists of subtitles.
Units can be connected through communication networks. The units can be denoted by objects and system software to model objects and system programs located on that device. The node may contain one or more devices.
The name of the device is preferable to be a noun, which refers to a hardware type. For example, “IBM System Z Mainframe”.
Archimate For Modeling Enterprise Architecture
System software presents software that provides or contributes to software or data data.
System software is a specialization of a node used to model the software environment, as a result of which objects are launched. This can be, for example, operating system, JEE application server, database system or workflow motor. Computer software can also be used, for example, to submit a medium communication index. Usually, the system software is combined with the unit representing the hardware to form a common loop.
The device or system software can be assigned to other system software; For example, modeling different layers of software that works on top of each other. System software can be appointed objects to simulate that these objects are located on that software. The system program can implement other system software. The node can consist of a system program.
The name of the system software is preferable to being a noun, which refers to the appearance of the performance environment. For example, “Jee Server”. The system program can be collected from other system software. For example, operating system containing database.
Reframing #archimate: About The Physical Domain, Layers And Recursion
Technological collaboration presents elements of the internal internal structure of two or more technologies working together to perform collective technological behavior.
Technological collaboration says what nodes and (or) other technological cooperation collaborate to do a certain task. Collaborative behavior, including the communication of these nodes, is modeled through technological interaction. Technological collaboration usually simulates logical or temporary cooperation in the nodes and does not exist a separate organization in the company.
Technological collaboration is a specialization of the elements of the internal internal structure of technology and consolidates two or more (collaborative) nodes and (or other technological collaboration. Technological collaboration is an element of internal active structure, which can be appointed elements of one or more technological interactions Or other technology for internal behavior, which simulates this behavior.
The technological interface indicates how the node technological services can be available through other nodes. The technological interface reveals the financial service for the environment. The same service can be exposed to different interfaces.
Using Archimate In Enterprise Architect
In a way, the technological interface defines a kind of contract as the conscious component of this interface must be performed. This may include, for example, parameters, used protocols, preliminary and additional terms and data formats.
The technological interface can be part of the node, which means that these interfaces are equipped with that loop and can serve other nodes. The technological interface can be assigned the technological service to identify this service to the environment.
Note: In previous versions of this standard, this element was called “infrastructure interface”. This use is still allowed, but writers and will be removed from the future version of the standard.
The path represents a connection between two or more nodes that these nodes can exchange data, energy or materials.
Archimate Application Landscape Overview
The rectette is used to model a logical communication (or distribution) relationship between nodes. It is carried out in one or more communications networks (or distributor networks during modeling physical elements. See Chapter 11), which represents the references to physical communication (or distribution). The properties (such as bandwidth, bandwidth, latency) are usually united from these underlying networks.
The path connects two or more nodes. The path is carried out in one or more networks. The path can consolidate nodes.
The communication network presents the infrastructure for physical communication. It provides basic services for pairing systems and provides the main mechanisms of opaque transfer. It contains hardware and software elements used by networks and physical communication, used by the system, and of course all other systems connected to the network “, as described by the Togaf Series Guide (TRM).
The connection network connects two or more devices. The most basic communication network is between two units, but it can include many links and related networking equipment. The network has properties such as bandwidth and latency. The communication network realizes one or more trails. It embodies the physical realization of the logical track between the nodes.
Example Of An Archimate Model
The communication network can consist of a subsurface. It can unite devices and system programs, such as routers, switches and refractors that are part of network infrastructure.
Note: This item used to be called “Network”. This use is still allowed, but writers and will be removed from the future version of the standard.
The two “Blade Systems” devices are connected to the “Data Center” communication network. This, for its part, is linked to another network of “wide area” through the “Data Center Switch” node. The two communications networks together implement the “Data Backup Way” road. Both Blade System devices and the “Data Center Switch” node have a technological interface “control interface”. The “Blade System 1” device is located on the “HyperWressive” software software system for hardware virtualization. The components of the two computer program are located “Hypervisor”. “Open Source Operating System” and “Real Estate System”, creating two virtual landlords, who have been modeled “Quote Virtual host”.
Elements of the behavior of the technology layer are similar to the elements of the behavior of other layers. Both in business and application layers, distinguish between technological services and the internal behavior of these nodes. Ie technological functions, technological processes and technological interactions that realize these services.

The technological function describes the internal behavior of the node. For a recreation user who performs a technological function, this feature is invisible. If the behavior is manifested outside, it is done through one or more technological services. The technological function is an abstract way. Only the required behavior is indicated.
Technology function can perform technological services. Other technology features Technology services
