📚 Architecture Reference & Implementation Guide

The following sections provide detailed architecture patterns, configuration examples, and reference code to guide your implementation.

Initial Configuration Requirements

1. Multiple Agents & Configuration

Goal: Deploy 2 specialized agents - "Customer Agent" (customer service) and "Inventory" (stock management)

📝 Note: The following azure.yaml and Bicep configurations are reference examples showing how to structure multi-agent deployments. You'll need to create these files and the corresponding agent implementations.

Configuration Steps:

# azure.yaml - Agent Configuration
services:
  agents:
    project: ./infra
    host: containerapp
    config:
      AGENTS_CONFIG: |
        {
          "customer": {
            "name": "Customer",
            "role": "Customer Service Representative",
            "description": "Handles general customer inquiries, returns, and support",
            "model": "gpt-4.1",
            "temperature": 0.7,
            "max_tokens": 500,
            "tools": ["search", "file_retrieval", "bing_search"]
          },
          "inventory": {
            "name": "Inventory",
            "role": "Inventory Management Specialist", 
            "description": "Manages stock levels, product availability, and fulfillment",
            "model": "gpt-4.1-mini",
            "temperature": 0.3,
            "max_tokens": 300,
            "tools": ["search", "database_query"]
          }
        }

Bicep Template Updates:

// infra/agents.bicep
param agentsConfig object = {
  customer: {
    name: 'Customer'
    model: 'gpt-4.1'
    capacity: 20
  }
  inventory: {
    name: 'Inventory'
    model: 'gpt-4.1-mini'
    capacity: 10
  }
}

resource agentDeployments 'Microsoft.App/containerApps@2024-03-01' = [for agent in items(agentsConfig): {
  name: 'agent-${agent.key}'
  properties: {
    template: {
      containers: [{
        name: 'agent-container'
        image: 'your-registry.azurecr.io/agent:latest'
        env: [
          {
            name: 'AGENT_NAME'
            value: agent.value.name
          }
          {
            name: 'AGENT_MODEL'
            value: agent.value.model
          }
        ]
      }]
    }
  }
}]

2. Multiple Models with Capacity Planning

Goal: Deploy chat model (Customer), embeddings model (search), and reasoning model (grader) with proper quota management

Multi-Region Strategy:

// infra/models.bicep
param modelDeployments array = [
  {
    name: 'gpt-4.1'
    region: 'eastus2'
    capacity: 20
    usage: 'chat'
    priority: 'high'
  }
  {
    name: 'text-embedding-ada-002'
    region: 'westus2'
    capacity: 30
    usage: 'search'
    priority: 'medium'
  }
  {
    name: 'gpt-4.1'
    region: 'francecentral'
    capacity: 15
    usage: 'grading'
    priority: 'low'
  }
]

// Capacity validation script

Customization & Updates

10. Container App Customization

Goal: Update container app configuration and replace with custom UI

Dynamic Configuration:

# azure.yaml - Container App Configuration
services:
  web-frontend:
    project: ./src/frontend
    host: containerapp
    config:
      AGENT_NAME: ${CUSTOMER_AGENT_NAME:-"Customer"}
      AGENT_DESCRIPTION: ${CUSTOMER_AGENT_DESCRIPTION:-"Customer Service Assistant"}
      COMPANY_NAME: "retail Retail"
      BRAND_COLOR: "#2E86AB"
      CUSTOM_LOGO_URL: ${LOGO_URL}

Custom Frontend Build:

# src/frontend/Dockerfile
FROM node:18-alpine AS builder

WORKDIR /app
COPY package*.json ./
RUN npm ci

COPY . .
ARG AGENT_NAME
ARG COMPANY_NAME
ARG BRAND_COLOR

# Replace placeholders during build
RUN sed -i "s/{{AGENT_NAME}}/$AGENT_NAME/g" src/config.js
RUN sed -i "s/{{COMPANY_NAME}}/$COMPANY_NAME/g" src/config.js
RUN sed -i "s/{{BRAND_COLOR}}/$BRAND_COLOR/g" src/styles/theme.css

RUN npm run build

FROM nginx:alpine
COPY --from=builder /app/dist /usr/share/nginx/html
COPY nginx.conf /etc/nginx/nginx.conf

Build and Deploy Script:

#!/bin/bash
# scripts/deploy_custom_frontend.sh

echo "Building and deploying custom frontend..."

# Build custom image with environment variables
docker build \
  --build-arg AGENT_NAME="$CUSTOMER_AGENT_NAME" \
  --build-arg COMPANY_NAME="retail Retail" \
  --build-arg BRAND_COLOR="#2E86AB" \
  -t retail-frontend:latest \
  ./src/frontend

# Push to Azure Container Registry
az acr build \
  --registry "$AZURE_CONTAINER_REGISTRY" \
  --image "retail-frontend:latest" \
  ./src/frontend

# Update container app
az containerapp update \
  --name "retail-frontend" \
  --resource-group "$AZURE_RESOURCE_GROUP" \
  --image "$AZURE_CONTAINER_REGISTRY.azurecr.io/retail-frontend:latest"

echo "Frontend deployed successfully!"

🔧 Troubleshooting Guide

Common Issues and Solutions

1. Container Apps Quota Limits

Problem: Deployment fails due to regional quota limits

Solution:

# Check current quota usage
az containerapp env show \
  --name "$CONTAINER_APPS_ENVIRONMENT" \
  --resource-group "$AZURE_RESOURCE_GROUP" \
  --query "properties.workloadProfiles"

# Request quota increase
az support tickets create \
  --ticket-name "ContainerApps-Quota-Increase" \
  --severity "minimal" \
  --contact-first-name "Your Name" \
  --contact-last-name "Last Name" \
  --contact-email "your.email@domain.com" \
  --contact-phone-number "+1234567890" \
  --description "Request quota increase for Container Apps in region X"

FAQ & Open-Ended Exploration

Frequently Asked Questions

Q: Is there an easy way to deploy multiple agents (design pattern)?

A: Yes! Use the Multi-Agent Pattern:

# azure.yaml - Multi-Agent Configuration
services:
  agent-orchestrator:
    project: ./infra
    host: containerapp
    config:
      AGENTS: |
        {
          "customer": {"type": "customer_service", "model": "gpt-4.1", "capacity": 20},
          "inventory": {"type": "inventory_management", "model": "gpt-4.1-mini", "capacity": 10},
          "returns": {"type": "returns_processing", "model": "gpt-4.1-mini", "capacity": 5}
        }

Q: Can I deploy "model router" as a model (cost implications)?

A: Yes, with careful consideration:

# Model Router Implementation
class ModelRouter:
    def __init__(self):
        self.routing_rules = {
            "simple_queries": {"model": "gpt-4.1-mini", "cost_per_1k": 0.00015},
            "complex_reasoning": {"model": "gpt-4.1", "cost_per_1k": 0.03},
            "embeddings": {"model": "text-embedding-ada-002", "cost_per_1k": 0.0001}
        }
    
    async def route_request(self, query: str, context: dict):
        """Route request to most cost-effective model"""
        complexity_score = self._analyze_complexity(query)
        
        if complexity_score < 0.3:
            return self.routing_rules["simple_queries"]
        else:
            return self.routing_rules["complex_reasoning"]
    
    def estimate_cost_savings(self, usage_patterns: dict):
        """Estimate cost savings from intelligent routing"""
        # Implementation would calculate potential savings
        pass

Cost Implications:

Savings: 60-80% cost reduction for simple queries
Trade-offs: Slight latency increase for routing logic
Monitoring: Track accuracy vs. cost metrics

Q: Can I start a fine-tuning job from an azd template?

A: Yes, using post-provisioning hooks:

#!/bin/bash
# hooks/postprovision.sh - Fine-tuning Integration

echo "Starting fine-tuning pipeline..."

# Upload training data
TRAINING_FILE_ID=$(python scripts/upload_training_data.py \
  --data-path "./data/fine_tuning/training.jsonl" \
  --openai-key "$AZURE_OPENAI_API_KEY")

# Start fine-tuning job
FINE_TUNE_JOB_ID=$(python scripts/start_fine_tuning.py \
  --training-file-id "$TRAINING_FILE_ID" \
  --model "gpt-4.1-mini")

# Store job ID for monitoring
echo "$FINE_TUNE_JOB_ID" > .azure/fine_tune_job_id

echo "Fine-tuning job started: $FINE_TUNE_JOB_ID"
echo "Monitor progress with: azd hooks run monitor-fine-tuning"
