Visualizing Cloud Designations with Mermaid

#cloud #designations #mermaid #community

Greetings to my fellow Technology Advocates and Specialists.

In this Session, I will demonstrate How to Create FlowChart Using Mermaid: A Step-by-Step Guide with Cloud Designations as Example.

I had the Privilege to talk on this topic in ONE Azure Community:-

REFERENCE LINKS:-
1. Overall Mermaid Documentation
2. Mermaid FlowChart Basic Syntax

WHAT IS MERMAID ?
1. Mermaid lets you create diagrams and visualizations using text and code.
2. It is based on JavaScript and inspired from Markdown Text.

NOTE:-
If users have familiarity or a working experience with Markdown, then understanding Mermaid Syntax comes easy.

MERMAID FLOWCHART: POINTS TO NOTE:-
1. Flowcharts are composed of nodes (geometric shapes) and edges (arrows or lines).
Possible FlowChart orientations are: a.) TB - Top to bottom; b.) TD - Top-down/ same as top to bottom; c.) BT - Bottom to top; d.) RL - Right to left; LR - Left to right.

USECASE #1:-
Create FlowChart.

Below follows the code:-

flowchart BT
    B(Chief Cloud Officer) --> A(Chief Technology Officer)
    C(Cloud Architect) --> B
    D(Cloud Service Manager) --> B
    E(Cloud Application Lead) --> B
    C1(Devops Engineer) --> C
    C2(IaC Developer) --> C1
    C3(IaC Operations Engineer) --> C2
    F(Support Engineer) --> C3
    D1(Cloud Operations Manager) --> D
    D2(Cloud Operations Engineer) --> D1
    F(Support Engineer) --> D2
    E1(Cloud Developer) --> E

EXPLANATION OF USECASE #1 MERMAID FLOWCHART CODE:-
1. `flowchart BT` - This Syntax indicates that the orientation of the FlowChart will be Bottom to Top.
2. `B(Chief Cloud Officer)` - This Syntax indicates a node with round edges.
3. `-->` - This Syntax indicates a link with arrow head.

OUTPUT FOR USECASE #1:-

USECASE #2:-
Create FlowChart using Subgraph.

Below follows the code:-

flowchart BT
    B(Chief Cloud Officer) --> A(Chief Technology Officer)
    C(Cloud Architect) --> B
    subgraph PLATFORM
    C1(Devops Engineer) --> C
    C2(IaC Developer) --> C1
    C3(IaC Operations Engineer) --> C2
    end
    D(Cloud Service Manager) --> B
    subgraph OPERATIONS
    D1(Cloud Operations Manager) --> D
    D2(Cloud Operations Engineer) --> D1
    end
    E(Cloud Application Lead) --> B
    subgraph APPLICATION
    E1(Cloud Developer) --> E    
    end
    subgraph SUPPORT
    F(Support Engineer) --> C3
    F(Support Engineer) --> D2
    end

EXPLANATION OF USECASE #2 MERMAID FLOWCHART CODE:-
1. `flowchart BT` - This Syntax indicates that the orientation of the FlowChart will be Bottom to Top.
2. `B(Chief Cloud Officer)` - This Syntax indicates a node with round edges.
3. `-->` - This Syntax indicates a link with arrow head.
4. `subgraph PLATFORM` or `subgraph OPERATIONS` or `subgraph SUPPORT` - This Syntax indicates grouping of nodes in a grid and providing a title to it.
