What is an Azure architecture diagram?

An Azure architecture diagram is a visual representation of your Microsoft Azure infrastructure — mapping compute resources, managed services, networking layers, security boundaries, and data flows. Azure architecture diagrams follow Microsoft's official icon set and the Azure resource hierarchy: Management Groups contain Subscriptions, which contain Resource Groups, which contain individual resources. Networking uses Virtual Networks (VNets) with subnets, Network Security Groups (NSGs), and Private Endpoints for secure service access.

These diagrams are essential for design reviews, Azure Well-Architected Framework assessments, compliance documentation (ISO 27001, SOC 2, HIPAA), cost optimization analysis, and onboarding engineers to production systems. Microsoft's Azure Solutions Architect Expert certification requires deep understanding of how to design and document complex, multi-region Azure architectures.

Core Azure architecture patterns

Web application with App Service and Cosmos DB

Azure Application Gateway (WAF) → App Service (Linux containers or code, auto-scaling, deployment slots for blue-green) → Azure Cosmos DB (globally distributed NoSQL, multi-region writes). Azure Cache for Redis for session state and caching. Azure Blob Storage for static assets and file uploads. Azure CDN accelerates global delivery. Azure Key Vault stores secrets and certificates. Azure Monitor + Application Insights for observability. Show the request flow, the managed identity connections from App Service to backend services, and the Cosmos DB replication topology.

AKS microservices

Azure Kubernetes Service cluster (system node pool + user node pools, Azure CNI networking, managed RBAC) running containerized microservices. Azure Container Registry stores images; Azure DevOps or GitHub Actions handles CI/CD. AGIC (Application Gateway Ingress Controller) or Nginx Ingress handles external traffic. Azure Service Bus for async messaging between services. Workload Identity (pod-level managed identity) allows pods to access Azure services without credentials. Azure Monitor Container Insights + Prometheus + Grafana for observability. Diagram the AKS cluster, node pools, namespaces, service mesh (Istio or OSM), and the CI/CD pipeline.

Azure OpenAI and AI Services

Azure OpenAI Service (GPT-4o, text-embedding-ada-002 deployments in a private endpoint) → Azure AI Search (vector + semantic search over indexed documents) → Azure Functions (orchestration, lightweight inference tasks). Azure Blob Storage stores source documents; Azure AI Document Intelligence extracts structured data. An API Management layer in front of Azure OpenAI adds rate limiting, logging, and key rotation without client changes. Managed Identity on all compute resources eliminates static API keys. Diagram shows the RAG pattern, the private networking, and the APIM gateway layer.

Event-driven serverless with Azure Functions

Azure Event Grid routes events from Blob Storage, Service Bus, Cosmos DB, and custom sources to Azure Functions triggers. Functions process events and fan out to further services: writing to Azure SQL Database, calling external APIs, publishing to Service Bus topics. Azure Logic Apps handle longer-running workflows with built-in connectors. Azure API Management exposes Functions as a managed API surface. Show the event sources, the Event Grid topic and subscriptions, the Function App with its individual functions, and the downstream services each function interacts with.

Key components to include in your Azure diagram

Subscription and resource group boundaries: Azure resources live in Subscriptions organized into Resource Groups. Show the subscription boundary, resource group boxes, and the resources within each — especially when using multiple subscriptions for environment isolation
VNet and subnet layout: Azure VNets are regional; subnets divide the VNet address space by workload tier. Show the VNet, subnets (web, app, data, management), NSG rules, and Private Endpoints for PaaS services like Cosmos DB, Key Vault, and Storage
Managed Identity connections: Azure Managed Identity (system-assigned or user-assigned) is the recommended way to authenticate compute to Azure services. Show which compute resources use managed identity and which Azure services they access — this replaces all secrets-in-environment-variables patterns
Private Endpoints: Private Endpoints project PaaS services (Storage, Cosmos DB, SQL, Key Vault, OpenAI) into your VNet with private IPs, preventing public internet access. Show Private Endpoints as security boundaries in your network diagram
Azure Monitor and Log Analytics: All Azure resources send logs and metrics to Log Analytics Workspaces. Show the diagnostic settings connections and the Application Insights instances monitoring each compute workload
Availability zones and regions: Azure regions contain 3 Availability Zones. Show zone-redundant resources (zone-redundant App Service plans, AKS node pools spread across zones, zone-redundant Storage) and secondary regions for geo-redundant deployments

Example prompt

"Azure architecture for an enterprise AI document processing platform. All resources in a single subscription, two resource groups: rg-network and rg-app. VNet with three subnets: frontend-subnet (App Service VNet Integration), backend-subnet (AKS node pool), data-subnet (Private Endpoints). Azure Application Gateway (WAF v2) routes external HTTPS traffic to App Service (Python FastAPI, consumption plan). App Service uses system-assigned Managed Identity to access: Azure OpenAI Service (GPT-4o deployment, private endpoint), Azure AI Search (vector search index over ingested documents), Azure Blob Storage (document uploads, private endpoint), Azure Key Vault (API keys, private endpoint). Azure Functions (Flex Consumption plan) handles async document ingestion triggered by Blob Storage events: extracts text with Azure AI Document Intelligence, chunks and embeds with Azure OpenAI (text-embedding-3-large), indexes in Azure AI Search. Cosmos DB (serverless, private endpoint) stores conversation history. Azure Service Bus (Premium, private endpoint) queues long-running jobs. All resource logs sent to Log Analytics Workspace; Application Insights on App Service and Functions. Zone-redundant in East US 2, with geo-replication to West US 3."

Frequently asked questions

How is Azure networking different from AWS in diagrams?

The biggest difference is VNet scope: Azure VNets are regional (like AWS VPCs), but Azure uses VNet Peering (not Transit Gateway) for hub-spoke topologies — the hub VNet typically hosts shared services (firewall, DNS, VPN gateway) and spoke VNets connect to it. Azure also has Network Security Groups (like AWS Security Groups) and the concept of Application Security Groups for tag-based rules. Private Link / Private Endpoints function similarly to AWS PrivateLink but are more commonly used for PaaS services in Azure since most Azure PaaS has no VPC-native option.

What is the Azure equivalent of AWS IAM roles?

Azure uses Managed Identity (system-assigned or user-assigned) as the equivalent of IAM roles for EC2/Lambda. A Managed Identity gives a compute resource (App Service, AKS pod via Workload Identity, Functions) an Azure AD identity that can be granted RBAC roles on other Azure resources. In architecture diagrams, show Managed Identity connections with a lock icon and annotate the RBAC roles assigned (e.g., "Storage Blob Data Reader", "Key Vault Secrets User").

Can I use ArchitectureDiagram.ai for Azure Well-Architected Framework reviews?

Yes. Describe your Azure architecture in plain English — specifying reliability (zone redundancy, geo-replication), security (Private Endpoints, Managed Identity, Defender for Cloud), cost optimization (reserved instances, consumption plans), operational excellence (Azure Monitor, Log Analytics), and performance efficiency (caching, CDN, auto-scaling). The AI generates a diagram that maps your architecture against the five WAF pillars, making it straightforward to identify gaps and prepare for design reviews.
