AWS Architecture Diagram Creation with Draw.io

Overview

Creates pixel-perfect AWS architecture diagrams in draw.io XML format using official AWS4 shape library. Generates production-ready .drawio files for diagrams.net.

When to Use

• AWS cloud architecture diagrams (VPC, subnets, services)
• Multi-tier application architectures on AWS
• Serverless designs (Lambda, API Gateway, DynamoDB)
• Network topology diagrams with security groups
• Infrastructure documentation for Well-Architected reviews

Instructions

File Structure

Every .drawio file follows this XML structure:

<mxfile host="app.diagrams.net" agent="Claude" version="24.7.17">
  <diagram id="aws-arch-1" name="AWS Architecture">
    <mxGraphModel dx="1434" dy="759" grid="1" gridSize="10" guides="1"
      tooltips="1" connect="1" arrows="1" fold="1" page="1"
      pageScale="1" pageWidth="1169" pageHeight="827" math="0" shadow="0">
      <root>
        <mxCell id="0" />
        <mxCell id="1" parent="0" />
        <!-- AWS shapes and connectors -->
      </root>
    </mxGraphModel>
  </diagram>
</mxfile>

Key rules:

• IDs "0" and "1" are reserved for root cells
• Use sequential integer IDs starting from "2"
• Landscape orientation (pageWidth="1169" pageHeight="827")
• All coordinates positive and aligned to grid (multiples of 10)

AWS4 Group Containers

Groups use container=1 with child shapes referencing via parent="groupId".

AWS Cloud (top-level boundary):

<mxCell id="2" value="AWS Cloud" style="points=[[0,0],[0.25,0],[0.5,0],[0.75,0],[1,0],[1,0.25],[1,0.5],[1,0.75],[1,1],[0.75,1],[0.5,1],[0.25,1],[0,1],[0,0.75],[0,0.5],[0,0.25]];outlineConnect=0;gradientColor=none;html=1;whiteSpace=wrap;fontSize=12;fontStyle=0;shape=mxgraph.aws4.group;grIcon=mxgraph.aws4.group_aws_cloud_alt;strokeColor=#232F3E;fillColor=none;verticalAlign=top;align=left;spacingLeft=30;fontColor=#232F3E;dashed=0;labelBackgroundColor=none;container=1;pointerEvents=0;collapsible=0;recursiveResize=0;" vertex="1" parent="1">
  <mxGeometry x="100" y="40" width="1000" height="700" as="geometry" />
</mxCell>

Region:

<mxCell id="3" value="us-east-1" style="...grIcon=mxgraph.aws4.group_region;strokeColor=#00A4A6;fontColor=#147EBA;dashed=1;..." vertex="1" parent="2">
  <mxGeometry x="20" y="40" width="960" height="640" as="geometry" />
</mxCell>

VPC:

<mxCell id="4" value="VPC (10.0.0.0/16)" style="...grIcon=mxgraph.aws4.group_vpc;strokeColor=#8C4FFF;fontColor=#AAB7B8;..." vertex="1" parent="3">
  <mxGeometry x="20" y="40" width="920" height="580" as="geometry" />
</mxCell>

Subnet styles:

• Public: strokeColor=#7AA116;fillColor=#E9F3D2;fontColor=#248814
• Private: strokeColor=#00A4A6;fillColor=#E6F6F7;fontColor=#147EBA

AWS4 Service Icons

Service icons use shape=mxgraph.aws4.resourceIcon with resIcon property.

CRITICAL: strokeColor=#ffffff is required for resourceIcon shapes to render white icon glyphs on colored backgrounds.

Standard service icon:

<mxCell id="10" value="Amazon S3" style="...gradientColor=#60A337;gradientDirection=north;fillColor=#277116;strokeColor=#ffffff;...shape=mxgraph.aws4.resourceIcon;resIcon=mxgraph.aws4.s3;" vertex="1" parent="1">
  <mxGeometry x="100" y="100" width="60" height="60" as="geometry" />
</mxCell>

Dedicated shapes (Lambda, ALB, Users) use strokeColor=none. See references/aws-shape-reference.md for complete shape catalog.

Service Color Codes

Each AWS service category uses official colors. All resourceIcon shapes must use strokeColor=#ffffff and gradientDirection=north. See references/aws-shape-reference.md for full color table.

Quick reference:

Connector Styles

Standard data flow:

edgeStyle=orthogonalEdgeStyle;rounded=0;orthogonalLoop=1;jettySize=auto;html=1;endArrow=open;endFill=0;strokeColor=#545B64;strokeWidth=2;

Encrypted connection:

edgeStyle=orthogonalEdgeStyle;rounded=0;orthogonalLoop=1;jettySize=auto;html=1;endArrow=classic;endFill=1;strokeColor=#DD344C;strokeWidth=2;dashed=1;dashPattern=5 5;

Async/event flow:

edgeStyle=orthogonalEdgeStyle;rounded=0;orthogonalLoop=1;jettySize=auto;html=1;endArrow=open;endFill=0;strokeColor=#E7157B;strokeWidth=2;dashed=1;

Layout Best Practices

1. Hierarchy: External → Internet → AWS Cloud → Region → VPC → Subnets → Services
2. Flow: Left-to-right for user traffic, top-to-bottom for tiers
3. Sizes: Service icons 60x60, grid-aligned coordinates
4. Spacing: 30-40px between icons, 20px padding inside containers
5. Labels: Place below icons (verticalLabelPosition=bottom)

Examples
