This articles introduces the technology layer and gives an overview of the main constructs available for modeling  technology architecture.The technology layer is split up into the following views of Conceptual:where we define the 'What',Logical:where we define the 'How',Physical.:captures the implementation and deployments of technology in the enterprise.

1. Conceptual:'What' technology capabilities are required to provide appropriate technology infrastructure.
• Technology Architecture Objective:A strategic goal associated
• Technology Architecture Principle:High level rules that govern the manner in which the technology capabilities are delivered.
• Technology Domain:Top level construct which provides a means of grouping technology.
• Technology Capability:What technology does what or needs to.
2. Logical:'How' the 'What' will be achieved.
• Technology Component:Describes the class of technology and what component is in the marketplace.
• Technology Function:Describes the functionality that a technology component or product can provide.
• Technology Provider:Captures a technology product or product build being used to provide components in the architecture.
• Technology Product Rule:A relationship class that enables more than one technology component.
3. Physical:Lowest level of abstraction and captures the instances of technology product.
• Technology Node:Captures the physical and virtual devices.The hostname is usually used as the name of the technology node.
• Technology Instance:A physical instance of an element.Technology Instance are sub-divided into the following:
• Application Software Instance
• Hardware Instance
• Technology Instance
• Infrastructure Software Instance
• Technology Deployment Group:Defines a template of the technology instance and node that are deployed on the node.The number of instances can be specified on the 'template'.

Clustering is a physical architecture decision that we capture in the Physical Technology Layer.How one models it depends on how the clustering technology works.This articles shows us the intricate details present in the technology layer and how it contributes to the modeling of technology.
