Deployment diagram

A deployment diagram[1] "specifies constructs that can be used to define the execution architecture of systems and the assignment of software artifacts to system elements.

"[1] To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts") run on each node (e.g., web application, database), and how the different pieces are connected (e.g. JDBC, REST, RMI).

A single node in a deployment diagram may conceptually represent multiple physical nodes, such as a cluster of database servers.

There are two types of Nodes: Device nodes are physical computing resources with processing memory and services to execute software, such as typical computers or mobile phones.
