Greetings to my fellow Technology Advocates and Specialists.

In this Session, I will demonstrate How to Create Azure Solutions Architecture Diagram by Code.

AUTOMATION OBJECTIVES:-

#	TOPICS
1.	Example #1: Create "Basic Azure App Service Architecture Diagram" by Code.
2.	Example #2: Create "Gaming Architecture Diagram" by Code.

PRE-REQUISITES:-
1. Python 3.6 or higher.
2. Graphviz
3. pip

VALIDATE PRE-REQUISITES:-

COMMANDS TO VERIFY:-

python --version
dot -V
pip --version

INSTALL DIAGRAMS:-

Install "diagrams" using "pip":-

pip install diagrams

CODE REPOSITORY:-

2. Diagram as Code - Installation
3. Diagram as Code - Examples
4. Diagram as Code - List of Azure Providers

CONCEPTS:-

I.) DIAGRAMS:-
1. Represents a global diagram context.
2. Diagram context can be created with Diagram class.
3. The first parameter of Diagram constructor will be used for output filename.

II.) NODES:-
1. Represents a single system component object.
2. A node object consists of three parts: i) Provider, ii) Resource type and iii) Name.

III.) CLUSTERS:-
1. Allows you group (or clustering) the nodes.

IV.) EDGES:-
1. Represents a connection between Nodes with some additional properties.

Now, we proceed in Creating Architecture Diagram using Diagrams and Python.

CONSTRUCT OF THE PYTHON CODE TO CREATE ARCHITECTURE DIAGRAM:-
1. Import Diagram, Cluster and Edge.
2. Import the Provider Icons for creating diagrams.
3. Creating the building blocks using Nodes and Cluster.
4. Connect the building blocks using Edges.

EXAMPLE #1:

Create "Basic Azure App Service Architecture Diagram" by Code.

Below follows the Python Code (Generate-Basic-Azure-App-service-Arch-Diagram.py):-

## Architecture Diagram: Basic Azure App Service:-

## Components include:-
# 1. User
# 2. Azure Entra ID
# 3. Azure Monitor
# 4. Azure Application Insights
# 5. Azure User Assigned Managed Identity
# 6. Azure Key Vault 
# 7. Azure App Services
# 8. Azure SQL Servers
