Deployment diagram

A deployment diagram allows you to illustrate how software systems and/or containers in the static model are mapped to infrastructure. This deployment diagram is based upon a UML deployment diagram, although simplified slightly to show the mapping between instances of software systems/containers and deployment nodes. A deployment node is something like physical infrastructure (e.g. a physical server or device), virtualised infrastructure (e.g. IaaS, PaaS, a virtual machine), containerised infrastructure (e.g. a Docker container), an execution environment (e.g. a database server, Java EE web/application server, Microsoft IIS), etc. Deployment nodes can be nested.

You may also want to include infrastructure nodes such as DNS services, load balancers, firewalls, etc.

Scope: One or more software systems.

Primary elements: Deployment nodes, software system instances, and container instances.
Supporting elements: Infrastructure nodes used in the deployment of the software system.

Intended audience: Technical people inside and outside of the software development team; including software architects, developers, infrastructure architects, and operations/support staff.


This is an example deployment diagram showing how the various containers of the Internet Banking System might be deployed in the bank's live environment.
