Deployment Definition

Deploy is the action and effect of deploying. This verb refers to unfold or extend what is folded; to exercise or put into practice an activity; to manifest a quality; or to arrange an exhibition or demonstration.

For example: “Few concerts have had a deployment of these characteristics”, “The deployment of the army scared the population”, “The visiting team surprised with its deployment throughout the playing field”.

Unfolding, therefore, is the opposite action of folding (folding). Suppose a person buys a curtain for his home that comes folded in a bag. In order to hang it from his bar, he will have to unfold it (ie take it out of its packaging and stretch it out so that it no longer has creases).

In the field of sport, deployment is usually associated with the ability of a player or a team to alternately occupy various positions on the field. The deployment can also refer to demonstrating qualities: “Nadal was brilliant with a display of offensive blows that cornered his rival”, “Messi was the best player on the field thanks to his deployment”.┬áSee Abbreviation Finder for acronyms related to Deployment.

In a military context, deployment consists of the advancement of the different columns of an army to occupy positions linked to a combat order. The deployment may involve the movement of soldiers, weapons and vehicles so that the forces are prepared to attack the enemy: “The president has ordered the deployment of the army to repel a possible invasion”, “The deployment of tanks does not scare us: we are ready to defend the territory.

A diagram class that uses the Unified Modeling Language to shape the material arrangement of artifacts in nodes is known by the name of deployment diagram. An artifact, in this context, is understood as the specification of physical data that is used or generated by a software development process, or is produced by the deployment and operation of a system.

When describing a website, for example, a deployment diagram shows the hardware components that make up the website (such as web, application, and database servers), the software components that run on each node (the aforementioned nodes, which can be the database and a web application, for example) and the way in which the different parts are connected to each other.

In the deployment diagram, nodes are represented by squares that contain smaller ones, symbolizing the artifacts assigned to them. In turn, nodes can have subnodes, which are nested as smaller squares within those of higher hierarchy; a single node can represent multiple physical nodes in a single deployment diagram, which is the case with a group of database servers.

Two types of nodes are recognized in the deployment diagram, which are as follows: device node, physical computing resources that use memory, and services to run programs (some common examples of this type of node are computers and mobile phones); runtime node, a computing resource running inside an external node and providing a service for hosting and running other software elements.

Deployment diagrams can be used for modeling: embedded systems, a set of devices that execute a large number of programs to interact with the physical world; client-server systems, focus on connecting a network of clients to a series of servers; fully distributed systems, have several levels of servers and must be prepared so that their topology can be continuously modified.
