Deployment diagrams in Software Engineering - Mini Project: Build & Apply

Understanding Deployment Diagrams

📖 Scenario: You are part of a software development team planning how to deploy a new web application. You need to create a deployment diagram to show how the software components will be arranged on hardware nodes.

🎯 Goal: Build a simple deployment diagram step-by-step that shows nodes and their connections, including software artifacts deployed on each node.

📋 What You'll Learn

Create nodes representing hardware or servers

Add software artifacts deployed on each node

Show communication paths between nodes

Label nodes and artifacts clearly

💡 Why This Matters

🌍 Real World

Deployment diagrams help teams plan how software will be installed and run on hardware, ensuring clear understanding of system setup.

💼 Career

Software engineers, system architects, and DevOps professionals use deployment diagrams to communicate system infrastructure and deployment strategies.

1

Create Nodes

Create two nodes named WebServer and DatabaseServer to represent the hardware servers in the deployment diagram.

Software Engineering

# Define nodes WebServer and DatabaseServer
# Your code here

Hint

Think of nodes as physical or virtual machines where software runs.

2

Add Software Artifacts

Add software artifacts named WebApp to WebServer and DB to DatabaseServer to represent deployed software components.

Software Engineering

WebServer = {
    "type": "Node",
    "name": "WebServer"
}
DatabaseServer = {
    "type": "Node",
    "name": "DatabaseServer"
}
# Add WebApp artifact to WebServer and DB artifact to DatabaseServer
# Your code here

Hint

Artifacts are software components deployed on nodes.

3

Define Communication Path

Create a communication path named WebToDB that connects WebServer and DatabaseServer to show how they communicate.

Software Engineering

WebServer = {
    "type": "Node",
    "name": "WebServer",
    "artifacts": ["WebApp"]
}
DatabaseServer = {
    "type": "Node",
    "name": "DatabaseServer",
    "artifacts": ["DB"]
}
# Define communication path WebToDB between WebServer and DatabaseServer
# Your code here

Hint

Communication paths show how nodes connect and exchange data.

4

Complete Deployment Diagram

Combine WebServer, DatabaseServer, and WebToDB into a dictionary named deployment_diagram representing the full deployment diagram.

Software Engineering

WebServer = {
    "type": "Node",
    "name": "WebServer",
    "artifacts": ["WebApp"]
}
DatabaseServer = {
    "type": "Node",
    "name": "DatabaseServer",
    "artifacts": ["DB"]
}
WebToDB = {
    "type": "CommunicationPath",
    "from": "WebServer",
    "to": "DatabaseServer"
}
# Create deployment_diagram dictionary including nodes and communication path
# Your code here

Hint

The deployment diagram groups all nodes and their connections together.
