AWS Architecture Diagram Generator
Describe your AWS infrastructure in plain English and get a professional architecture diagram in seconds. Visualize EC2 instances, ECS clusters, Lambda functions, RDS databases, S3 buckets, VPCs, CloudFront distributions, load balancers, and the connections between them — without spending an hour in a drag-and-drop editor.
What is an AWS architecture diagram?
An AWS architecture diagram is a visual map of your Amazon Web Services infrastructure — showing compute resources, managed services, networking layers, security boundaries, and data flows. AWS architecture diagrams follow AWS's official icon set and grouping conventions: regions contain availability zones, VPCs contain subnets, and services are grouped into their logical tiers (frontend, backend, database, messaging, etc.).
These diagrams are used for cloud design reviews, incident postmortems, security audits, compliance documentation (SOC 2, HIPAA, FedRAMP), cost optimization workshops, and onboarding new engineers to a production system. AWS Well-Architected Framework reviews often start with an accurate architecture diagram as the baseline artifact.
Core AWS architecture patterns
Three-tier web application
The foundational AWS pattern: Route 53 → CloudFront CDN → Application Load Balancer → Auto Scaling Group of EC2 instances (web tier) → Application Load Balancer → EC2 or ECS (app tier) → RDS Multi-AZ (database tier). The frontend tier sits in public subnets; app and database tiers sit in private subnets. NAT Gateways allow outbound traffic from private subnets. Your diagram should show each tier in a separate subnet group, with security group boundaries indicating allowed traffic flows.
Serverless event-driven architecture
API Gateway → Lambda functions → DynamoDB or Aurora Serverless. Async workflows use SQS queues or SNS topics to decouple Lambda invocations. S3 events trigger Lambda for file processing. EventBridge routes scheduled and custom events to Lambda targets. Step Functions orchestrate multi-step Lambda workflows with retry logic and error handling. Diagram the event sources, Lambda function names, the services they read from and write to, and the IAM role boundaries.
ECS microservices on Fargate
Multiple ECS services running containerized microservices on Fargate, fronted by an Application Load Balancer with path-based routing rules. Services communicate over an internal load balancer or AWS App Mesh service mesh. ECR stores container images; CodePipeline + CodeBuild handles CI/CD. Secrets Manager stores credentials injected at runtime. CloudWatch Container Insights handles observability. Your diagram should show the ECS cluster, individual services with task counts, ALB routing rules, and the CI/CD pipeline feeding into ECR.
Data lake on S3
Raw data lands in S3 (raw zone) via Kinesis Firehose or AWS Glue ETL jobs. Glue Crawlers catalog the data in the AWS Glue Data Catalog. Athena queries the S3 data directly using SQL. Processed data moves to a curated S3 zone and is loaded into Redshift for BI tools like QuickSight. Lake Formation enforces fine-grained access control across the lake. Diagram each S3 zone, the data flow between them, and the query paths for each consumer.
Key components to include in your AWS diagram
- Region and AZ groupings: Show which resources are in which AWS Region and availability zones — critical for understanding HA and failover behavior
- VPC and subnet boundaries: Public vs. private subnets, CIDR blocks, route table associations, and internet/NAT gateway placement
- Load balancers and routing: ALB/NLB placement, target groups, health check paths, and listener rules for path/host-based routing
- Security group flow: Which security groups allow traffic between tiers — even if simplified as boundary boxes rather than full rule tables
- Managed services: RDS, ElastiCache, SQS, SNS, DynamoDB, S3 buckets — labeled with instance type or capacity class where relevant
- IAM trust boundaries: Which Lambda or EC2 roles have access to which services, especially for cross-account architectures
- Observability stack: CloudWatch Log Groups, metrics dashboards, X-Ray traces, and alert routing to SNS or PagerDuty

Frequently asked questions
What notation does AWS use for architecture diagrams?
AWS publishes an official icon set (updated annually) with icons for each AWS service, grouped by category: Compute, Storage, Database, Networking, Security, ML, and more. The standard grouping convention uses dashed rectangles for Regions, solid rectangles for VPCs, and lighter rectangles for subnets and availability zones. AWS also publishes PowerPoint, draw.io, and Lucidchart stencils. ArchitectureDiagram.ai generates diagrams that follow these conventions and exports to draw.io format for further editing with official AWS shapes.
Can I export my AWS diagram to draw.io or Lucidchart?
Yes. ArchitectureDiagram.ai exports diagrams in draw.io (XML) format, which you can open directly in draw.io (diagrams.net) or import into Confluence via the draw.io plugin. From draw.io you can also export to Lucidchart-compatible formats. The Mermaid export works for diagrams embedded in GitHub wikis, Notion, and documentation sites.
What is the difference between an AWS architecture diagram and a cloud-agnostic diagram?
AWS architecture diagrams use AWS-specific service names, icons, and grouping conventions (Regions, AZs, VPCs). Cloud-agnostic diagrams use generic labels (Load Balancer, Database, Cache, Queue) that apply regardless of the cloud provider. Use AWS-specific diagrams for detailed implementation documentation, security reviews, and operations runbooks. Use cloud-agnostic diagrams for design discussions, vendor evaluation, and cross-cloud comparison.
