GCP Deployment¶

Prerequisites (GCP)¶

Required Tools¶

# Google Cloud SDK
curl https://sdk.cloud.google.com | bash
gcloud init

# Docker
# Install from https://docs.docker.com/get-docker/

# Go 1.22+ (for local builds)
# Install from https://go.dev/dl/

Required Permissions¶

You need the following IAM roles on your GCP project:

roles/owner or these specific roles:
roles/run.admin
roles/artifactregistry.admin
roles/iam.serviceAccountAdmin
roles/secretmanager.admin
roles/datastore.owner
roles/logging.admin

Environment Variables¶

export GCP_PROJECT_ID="your-project-id"
export GCP_REGION="us-central1"

Setup (GCP)¶

1. Create or Select Project¶

# Create new project
gcloud projects create $GCP_PROJECT_ID --name="Agent Exchange"

# Or select existing project
gcloud config set project $GCP_PROJECT_ID

2. Enable Billing¶

Ensure billing is enabled in the GCP Console.

3. Run Setup Script¶

./hack/deploy/setup-gcp.sh

This script will: - Enable required APIs - Create Artifact Registry repository - Create service accounts with proper roles - Set up Workload Identity for GitHub Actions - Create Firestore database - Create initial secrets

4. Manual API Enablement (if needed)¶

gcloud services enable \
  run.googleapis.com \
  artifactregistry.googleapis.com \
  firestore.googleapis.com \

Environment Variables¶

All Services¶

Variable	Description	Default
`PORT`	HTTP port	`8080`
`ENVIRONMENT`	Environment name	`production`
`LOG_LEVEL`	Logging level	`info`

Service-Specific¶

Service	Variables
`aex-gateway`	`WORK_PUBLISHER_URL`, `BID_GATEWAY_URL`, `PROVIDER_REGISTRY_URL`, `SETTLEMENT_URL`, `IDENTITY_URL`
`aex-work-publisher`	`STORE_TYPE`, `PROVIDER_REGISTRY_URL`

`aex-bid-evaluator`	`BID_GATEWAY_URL`, `TRUST_BROKER_URL`
`aex-contract-engine`	`BID_GATEWAY_URL`, `SETTLEMENT_URL`

Scaling¶

GCP Auto-scaling¶

# High-throughput services (gateway)
--concurrency=250

# CPU-intensive services (bid-evaluator)
--concurrency=50

# Cold start optimization
--min-instances=1 --cpu-boost

AWS Auto-scaling¶

# Register scalable target
aws application-autoscaling register-scalable-target \
  --service-namespace ecs \
  --resource-id service/aex-cluster/aex-gateway \
  --scalable-dimension ecs:service:DesiredCount \
  --min-capacity 1 \
  --max-capacity 10

# Create scaling policy (target tracking)
aws application-autoscaling put-scaling-policy \
  --service-namespace ecs \
  --resource-id service/aex-cluster/aex-gateway \
  --policy-name cpu-tracking \
  --policy-type TargetTrackingScaling \
  --target-tracking-scaling-policy-configuration '{
    "TargetValue": 70.0,
    "PredefinedMetricSpecification": {
      "PredefinedMetricType": "ECSServiceAverageCPUUtilization"
    },
    "ScaleOutCooldown": 60,
    "ScaleInCooldown": 300
  }'

# Manual scaling
aws ecs update-service \
  --cluster aex-cluster \
  --service aex-gateway \
  --desired-count 5

Security Best Practices¶

Authentication¶

Disable unauthenticated access in production
Use service-to-service authentication
Validate API keys against Identity service
Implement rate limiting

Network Security¶

GCP¶

# VPC Connector for private networking
--vpc-connector=aex-connector
--vpc-egress=private-ranges-only

AWS¶

Services run in private subnets
ALB is the only public-facing component
Security groups restrict traffic between tiers

Secret Management¶

Never commit secrets to code
Use Secret Manager (GCP) or Secrets Manager (AWS)
Rotate secrets regularly
Use separate secrets per environment

Troubleshooting¶

GCP¶

Service Won't Start¶

gcloud run services logs read SERVICE_NAME --region=$GCP_REGION
gcloud run revisions describe REVISION_NAME --region=$GCP_REGION

Connection Refused¶

curl -H "Authorization: Bearer $(gcloud auth print-identity-token)" \
  https://target-service-xxx.run.app/health

AWS¶

Task Fails to Start¶

aws ecs describe-tasks \
  --cluster aex-cluster \
  --tasks $(aws ecs list-tasks --cluster aex-cluster --service-name aex-gateway \
    --desired-status STOPPED --query 'taskArns[0]' --output text) \
  --query 'tasks[0].stoppedReason'

Service Unhealthy¶

aws elbv2 describe-target-health \
  --target-group-arn $(aws elbv2 describe-target-groups \
    --names aex-gateway-tg --query 'TargetGroups[0].TargetGroupArn' --output text)

Database Connection Issues¶

aws ecs execute-command \
  --cluster aex-cluster \
  --task <task-id> \
  --container aex-gateway \
  --interactive \
  --command "/bin/sh"

Teardown¶

Validate Before Teardown¶

# GCP - validate what will be deleted
./hack/deploy/teardown-gcp.sh validate

# AWS - validate what will be deleted
./hack/deploy/teardown-aws.sh validate

Execute Teardown¶

# GCP - delete all resources
./hack/deploy/teardown-gcp.sh

# AWS - delete all resources
./hack/deploy/teardown-aws.sh

Make Targets¶

# GCP

Demo Deployment (Local Development)¶

The demo showcases the complete AEX + A2A + AP2 flow with legal agents and payment processors.

Quick Start Demo¶

cd demo

# Start everything
docker-compose up -d

# Access UI
open http://localhost:8502

Step-by-Step Demo (for presentations)¶

cd demo

# 1. Stop everything and clean up
docker-compose down -v

# 2. Start AEX infrastructure only (no agents)
docker-compose up -d mongo aex-identity aex-provider-registry aex-trust-broker \
  aex-bid-gateway aex-bid-evaluator aex-contract-engine aex-work-publisher \
  aex-settlement aex-credentials-provider aex-telemetry aex-gateway

# 3. Start UI without dependencies
docker-compose up -d --no-deps demo-ui-nicegui

# 4. Verify empty marketplace
curl -s http://localhost:8085/providers | jq '.total'  # Should be 0

# 5. Add agents one by one (during presentation)
docker-compose up -d legal-agent-a      # Budget Legal
docker-compose up -d legal-agent-b      # Standard Legal
docker-compose up -d legal-agent-c      # Premium Legal

# 6. Add payment agents
docker-compose up -d payment-legalpay payment-contractpay payment-compliancepay

# 7. Add orchestrator
docker-compose up -d orchestrator

# 8. Open browser and run the demo
open http://localhost:8502

Demo Verification Commands¶

# Check AEX health
curl http://localhost:8080/health

# Count registered providers
curl -s http://localhost:8085/providers | jq '.total'

# List provider names
curl -s http://localhost:8085/providers | jq '.providers[].name'

# Check agent card
curl -s http://localhost:8100/.well-known/agent.json | jq '{name, description}'

Demo UI Features¶

The NiceGUI demo interface (port 8502) provides: - Real-time agent registration display (auto-refreshes every 5 seconds) - Work submission form - Live bid collection and comparison - Contract award with configurable strategies (balanced, lowest price, best quality) - A2A execution visualization - AP2 payment processing with cashback rewards - Settlement summary with ledger updates
