Technology layer view: servers, networks, system software, and their hosting relationships.

Key Elements

Layer	Macros Used
Technology	`Technology_Device`, `Technology_Node`, `Technology_SystemSoftware`, `Technology_Artifact`, `Technology_CommunicationNetwork`, `Technology_Service`

Example

Three-tier deployment: load balancer → app cluster → database cluster with shared storage network:

@startuml
!include <archimate/Archimate>

Technology_CommunicationNetwork(inet, "Internet")
Technology_CommunicationNetwork(lan, "Internal LAN")
Technology_CommunicationNetwork(san, "Storage Network")

rectangle "DMZ" {
  Technology_Device(lb, "Load Balancer")
  Technology_SystemSoftware(nginx, "Nginx")
}

rectangle "Application Tier" {
  Technology_Node(app1, "App Server 1")
  Technology_Node(app2, "App Server 2")
  Technology_SystemSoftware(jvm1, "JVM Runtime")
  Technology_SystemSoftware(jvm2, "JVM Runtime")
  Technology_Artifact(war, "app.war")
}

rectangle "Database Tier" {
  Technology_Device(dbPrimary, "DB Primary")
  Technology_Device(dbReplica, "DB Replica")
  Technology_SystemSoftware(pg1, "PostgreSQL")
  Technology_SystemSoftware(pg2, "PostgreSQL")
  Technology_Device(nas, "NAS Storage")
}

Rel_Association(inet, lb, "")
Rel_Assignment(lb, nginx, "")
Rel_Association(lb, lan, "")

Rel_Association(lan, app1, "")
Rel_Association(lan, app2, "")
Rel_Assignment(app1, jvm1, "")
Rel_Assignment(app2, jvm2, "")
Rel_Assignment(jvm1, war, "")
Rel_Assignment(jvm2, war, "")

Rel_Association(lan, dbPrimary, "")
Rel_Assignment(dbPrimary, pg1, "")
Rel_Assignment(dbReplica, pg2, "")
Rel_Serving(dbReplica, dbPrimary, "replication")
Rel_Association(san, dbPrimary, "")
Rel_Association(san, dbReplica, "")
Rel_Association(san, nas, "")

Pattern Notes

Device vs Node — Technology_Device for physical hardware (load balancer, DB servers, NAS); Technology_Node for logical compute units (app servers)
SystemSoftware — Technology_SystemSoftware for runtime environments (Nginx, JVM, PostgreSQL) assigned to their host
Artifact — Technology_Artifact for deployable units (app.war) assigned to the runtime
Communication Networks — Technology_CommunicationNetwork for network segments (Internet, LAN, SAN); elements connect via Rel_Association
Replication — Rel_Serving between DB replica and primary shows data replication relationship
Zone grouping — rectangle "DMZ", "Application Tier", "Database Tier" represent network security zones
