Quick Start

1. Deploy Production Infrastructure (AWS)

# Navigate to production environment
cd terraform/environments/prod

# Create terraform.tfvars
cat > terraform.tfvars <<EOF
environment = "production"
region = "us-east-1"
domain_name = "mockupaws.com"
certificate_arn = "arn:aws:acm:..."
ecr_repository_url = "123456789012.dkr.ecr.us-east-1.amazonaws.com/mockupaws"
alert_email = "ops@mockupaws.com"
EOF

# Initialize and deploy
terraform init
terraform plan
terraform apply

2. Configure Server (Docker Compose)

# Run Ansible playbook
ansible-playbook -i ansible/inventory/production ansible/playbooks/setup-server.yml

3. Deploy Monitoring Stack

# Start monitoring services
docker-compose -f docker-compose.monitoring.yml up -d

# Access:
# - Prometheus: http://localhost:9090
# - Grafana: http://localhost:3000 (admin/admin)
# - Alertmanager: http://localhost:9093

Terraform Modules

VPC Module

Creates a production-ready VPC with:

• Public, private, and database subnets
• NAT Gateways
• VPC Flow Logs
• Network ACLs

RDS Module

Creates PostgreSQL database with:

• Multi-AZ deployment
• Automated backups
• Encryption at rest
• Performance Insights
• Enhanced monitoring

ECS Module

Creates container orchestration with:

• Fargate launch type
• Auto-scaling policies
• Service discovery
• Circuit breaker deployment

CloudFront Module

Creates CDN with:

• SSL/TLS termination
• WAF integration
• Origin access identity
• Cache behaviors

Monitoring

Prometheus Metrics

• Application metrics (latency, errors, throughput)
• Infrastructure metrics (CPU, memory, disk)
• Database metrics (connections, query performance)
• Redis metrics (memory, hit rate, connections)

Grafana Dashboards

1. Overview Dashboard - Application health and performance
2. Database Dashboard - PostgreSQL metrics
3. Infrastructure Dashboard - Server and container metrics
4. Business Dashboard - User activity and scenarios

Alerting Rules

• Critical: Service down, high error rate, disk full
• Warning: High latency, memory usage, slow queries
• Info: Low traffic, deployment notifications

Deployment

CI/CD Pipeline

GitHub Actions workflows:

• ci.yml - Build, test, security scans
• deploy-production.yml - Deploy to production

Deployment Methods

1. ECS Blue-Green - Zero-downtime deployment
2. Docker Compose - Single server deployment
3. Kubernetes - Enterprise multi-region deployment

Security

Network Security

• Security groups with minimal access
• Network ACLs
• VPC Flow Logs
• AWS WAF rules

Data Security

• Encryption at rest (KMS)
• TLS 1.3 in transit
• Secrets management (AWS Secrets Manager)
• Regular security scans

Access Control

• IAM roles with least privilege
• MFA enforcement
• Audit logging
• Regular access reviews

Cost Optimization

Reserved Capacity

• RDS Reserved Instances: ~40% savings
• ElastiCache Reserved Nodes: ~30% savings
• Savings Plans for compute: ~20% savings

Right-sizing

• Use Fargate Spot for non-critical workloads
• Enable auto-scaling to handle traffic spikes
• Archive old data to Glacier

Monitoring Costs

• Set up AWS Budgets
• Enable Cost Explorer
• Tag all resources
• Review monthly cost reports

Troubleshooting

Common Issues

Terraform State Lock

# Force unlock (use with caution)
terraform force-unlock <LOCK_ID>

ECS Deployment Failure

# Check service events
aws ecs describe-services --cluster mockupaws-production --services backend

# Check task logs
aws logs tail /ecs/mockupaws-production --follow

Database Connection Issues

# Check RDS status
aws rds describe-db-instances --db-instance-identifier mockupaws-production

# Test connection
pg_isready -h <endpoint> -p 5432 -U mockupaws_admin

Maintenance

Regular Tasks

• Daily: Review alerts, check backups
• Weekly: Review performance metrics, update dependencies
• Monthly: Security patches, cost review
• Quarterly: Disaster recovery test, access review

Updates

# Update Terraform providers
terraform init -upgrade

# Update Ansible roles
ansible-galaxy install -r requirements.yml --force

# Update Docker images
docker-compose -f docker-compose.monitoring.yml pull
docker-compose -f docker-compose.monitoring.yml up -d
