# Azure Architecture Diagrams Skill

A comprehensive technical diagramming toolkit for solutions architects, presales engineers,
and developers. Generate professional diagrams for proposals, documentation, and architecture
reviews.

## ⚡ Execution Method

**Always execute diagram code inline** - do not create a separate .py file:

```bash
python3 << 'EOF'
from diagrams import Diagram, Cluster
from diagrams.azure.compute import AKS
from diagrams.azure.database import CosmosDb

with Diagram("My Architecture", filename="/mnt/user-data/outputs/diagram", show=False):
    AKS("aks-prod") >> CosmosDb("cosmos-prod")

EOF
```

This approach:

- ✅ Generates the diagram directly
- ✅ No temporary .py files left on disk
- ✅ Cleaner workflow

**Do NOT do this:**

```bash
# ❌ Don't create a file first
cat > diagram.py << 'EOF'
...
EOF
python3 diagram.py  # Leaves diagram.py behind
```

## 📊 Diagram Types

## 🔥 Bonus: Generate from Code

Can also create diagrams directly from infrastructure code:

```
Read the Bicep files in /infra and generate an architecture diagram
```

```
Analyze our Terraform modules and create a diagram grouped by subnet
```

```
Read azure-pipelines.yml and create a CI/CD pipeline diagram
```

Supports: **Bicep**, **Terraform**, **ARM Templates**, **Azure Pipelines YAML**, **GitHub Actions**

See `references/iac-to-diagram.md` for detailed prompts and examples.

## Common Architecture Patterns

### Web Application (3-Tier)

```python
from diagrams.azure.network import ApplicationGateway
from diagrams.azure.compute import AppServices
from diagrams.azure.database import SQLDatabases

gateway >> AppServices("Web") >> SQLDatabases("DB")
```

### Microservices with AKS

```python
from diagrams.azure.compute import AKS, ACR
from diagrams.azure.network import ApplicationGateway
from diagrams.azure.database import CosmosDb

gateway >> AKS("Cluster") >> CosmosDb("Data")
ACR("Registry") >> AKS("Cluster")
```

### Serverless / Event-Driven

```python
from diagrams.azure.compute import FunctionApps
from diagrams.azure.integration import EventGridTopics, ServiceBus
from diagrams.azure.storage import BlobStorage

EventGridTopics("Events") >> FunctionApps("Process") >> ServiceBus("Queue")
BlobStorage("Trigger") >> FunctionApps("Process")
```

### Data Platform

```python
from diagrams.azure.analytics import DataFactories, Databricks, SynapseAnalytics
from diagrams.azure.storage import DataLakeStorage

DataFactories("Ingest") >> DataLakeStorage("Lake") >> Databricks("Transform") >> SynapseAnalytics("Serve")
```

### Hub-Spoke Networking

```python
from diagrams.azure.network import VirtualNetworks, Firewall, VirtualNetworkGateways

with Cluster("Hub"):
    firewall = Firewall("Firewall")
    vpn = VirtualNetworkGateways("VPN")

with Cluster("Spoke 1"):
    spoke1 = VirtualNetworks("Workload 1")

spoke1 >> firewall
```

## Connection Syntax

```python
# Basic connections
a >> b                              # Simple arrow
a >> b >> c                         # Chain
a >> [b, c, d]                      # Fan-out (one to many)
[a, b] >> c                         # Fan-in (many to one)

# Labeled connections
a >> Edge(label="HTTPS") >> b       # With label
a >> Edge(label="443") >> b         # Port number

# Styled connections
a >> Edge(style="dashed") >> b      # Dashed line (config/secrets)
a >> Edge(style="dotted") >> b      # Dotted line
a >> Edge(color="red") >> b         # Colored
a >> Edge(color="red", style="bold") >> b  # Combined

# Bidirectional
a >> Edge(label="sync") << b        # Two-way
a - Edge(label="peer") - b          # Undirected
```

## Diagram Attributes

```python
with Diagram(
    "Title",
    show=False,                    # Don't auto-open
    filename="output",             # Output filename (no extension)
    direction="TB",                # TB, BT, LR, RL
    outformat="png",               # png, jpg, svg, pdf
    graph_attr={
        "splines": "spline",       # Curved edges
        "nodesep": "1.0",          # Horizontal spacing
        "ranksep": "1.0",          # Vertical spacing
        "pad": "0.5",              # Graph padding
        "bgcolor": "white",        # Background color
    }
):
```

## Clusters (Grouping)

```python
with Cluster("Resource Group"):
    with Cluster("Subnet A"):
        vm1 = VM("VM 1")
        vm2 = VM("VM 2")

    with Cluster("Subnet B"):
        db = SQLDatabases("Database")
```

Cluster styling:

```python
with Cluster("Styled", graph_attr={"bgcolor": "#E8F4FD", "style": "rounded"}):
```

## Troubleshooting

### Overlapping Nodes

Increase spacing for complex diagrams:

```python
graph_attr={
    "nodesep": "1.2",   # Horizontal (default 0.25)
    "ranksep": "1.2",   # Vertical (default 0.5)
    "pad": "0.5"
}
```

### Floating Edge Labels

Use `xlabel` instead of `label`:

```python
# Instead of Edge(label="text")
a >> Edge(xlabel="text") >> b
```

### Excessive Whitespace

Compress the output:

```python
graph_attr={"pad": "0.2", "margin": "0", "ratio": "compress"}
```

### Force Horizontal Alignment

Use subgraphs with same rank:

```python
with Diagram(...):
    # These will be on the same horizontal level
    with Cluster("") as same_level:
        same_level.dot.body.append('rank=same')
        a = ServiceA("A")
        b = ServiceB("B")
```

See `references/preventing-overlaps.md` for detailed guidance.

## Output Location

For Claude Code / GitHub Copilot, save to outputs:

```python
with Diagram("Name", show=False, filename="/mnt/user-data/outputs/diagram"):
    # ...
```

## ⚠️ CRITICAL: Professional Output Standards

### The Key Setting: `labelloc='t'`

To keep labels inside cluster boundaries with the `diagrams` library, **put labels ABOVE icons**:

```python
node_attr = {
    "fontname": "Arial Bold",
    "fontsize": "11",
    "labelloc": "t",  # KEY: Labels at TOP - stays inside clusters!
}

with Diagram("Title", node_attr=node_attr, ...):
    # Your diagram code
```

### Full Professional Template

```python
from diagrams import Diagram, Cluster, Edge
from diagrams.azure.compute import AKS
from diagrams.azure.database import SQLDatabases

graph_attr = {
    "bgcolor": "white",
    "pad": "0.8",
    "nodesep": "0.9",
    "ranksep": "0.9",
    "splines": "spline",
    "fontname": "Arial Bold",
    "fontsize": "16",
    "dpi": "200",              # High resolution
}

node_attr = {
    "fontname": "Arial Bold",  # Bold for readability
    "fontsize": "11",
    "labelloc": "t",           # Labels ABOVE icons - KEY!
}

cluster_style = {"margin": "30", "fontname": "Arial Bold", "fontsize": "14"}

with Diagram("My Architecture",
             direction="TB",
             graph_attr=graph_attr,
             node_attr=node_attr):

    with Cluster("Data Tier", graph_attr=cluster_style):
        sql = SQLDatabases("sql-myapp-prod\nS3 tier")
```

### Professional Standards Checklist

| Check                      | Requirement                              |
| -------------------------- | ---------------------------------------- |
| ✅ **labelloc='t'**        | Labels above icons (stays in clusters)   |
| ✅ **Bold fonts**          | `fontname="Arial Bold"` for readability  |
| ✅ **Full resource names** | Actual names from IaC, not abbreviations |
| ✅ **High DPI**            | `dpi="200"` for crisp text               |
| ✅ **Azure icons**         | Use `diagrams.azure.*` components        |
| ✅ **Cluster margins**     | `margin="30"` or higher                  |

**⚠️ ALWAYS review the output image before delivering. If ANY text is outside boxes, increase margins or simplify clusters.**
