🎉 Epic 3 Complete: Production Readiness & Observability

Successfully implemented comprehensive monitoring and alerting infrastructure for the Meteor platform across all three stories of Epic 3: **Story 3.5: 核心业务指标监控 (Core Business Metrics Monitoring)** - Instrumented NestJS web backend with CloudWatch metrics integration using prom-client - Instrumented Go compute service with structured CloudWatch metrics reporting - Created comprehensive Terraform infrastructure from scratch with modular design - Built 5-row CloudWatch dashboard with application, error rate, business, and infrastructure metrics - Added proper error categorization and provider performance tracking **Story 3.6: 关键故障告警 (Critical System Alerts)** - Implemented SNS-based alerting infrastructure via Terraform - Created critical alarms for NestJS 5xx error rate (>1% threshold) - Created Go service processing failure rate alarm (>5% threshold) - Created SQS queue depth alarm (>1000 messages threshold) - Added actionable alarm descriptions with investigation guidance - Configured email notifications with manual confirmation workflow **Cross-cutting Infrastructure:** - Complete AWS infrastructure as code with Terraform (S3, SQS, CloudWatch, SNS, IAM, optional RDS/Fargate) - Structured logging implementation across all services (NestJS, Go, Rust) - Metrics collection following "Golden Four Signals" observability approach - Configurable thresholds and deployment-ready monitoring solution The platform now has production-grade observability with comprehensive metrics collection, centralized monitoring dashboards, and automated critical system alerting. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+# Meteor Fullstack Infrastructure
+
+This directory contains Terraform configuration for the Meteor fullstack application AWS infrastructure.
+
+## Overview
+
+The infrastructure includes:
+- **S3 bucket** for storing meteor event files and media
+- **SQS queue** for processing meteor events with dead letter queue
+- **CloudWatch dashboard** for comprehensive monitoring
+- **IAM policies** and roles for service permissions
+- **Optional RDS PostgreSQL** instance
+- **Optional VPC and Fargate** configuration for containerized deployment
+
+## Quick Start
+
+1. **Install Terraform** (version >= 1.0)
+2. **Configure AWS credentials**:
+   ```bash
+   aws configure
+   # OR set environment variables:
+   export AWS_ACCESS_KEY_ID="your-access-key"
+   export AWS_SECRET_ACCESS_KEY="your-secret-key"
+   export AWS_DEFAULT_REGION="us-east-1"
+   ```
+
+3. **Copy and customize variables**:
+   ```bash
+   cp terraform.tfvars.example terraform.tfvars
+   # Edit terraform.tfvars with your desired configuration
+   ```
+
+4. **Initialize and apply**:
+   ```bash
+   terraform init
+   terraform plan
+   terraform apply
+   ```
+
+## Configuration Options
+
+### Basic Setup (Default)
+- Creates S3 bucket and SQS queue only
+- Uses external database and container deployment
+- Minimal cost option
+
+### With RDS Database
+```hcl
+enable_rds = true
+rds_instance_class = "db.t3.micro"  # or larger for production
+```
+
+### With VPC and Fargate
+```hcl
+enable_fargate = true
+web_backend_cpu = 256
+web_backend_memory = 512
+compute_service_cpu = 256
+compute_service_memory = 512
+```
+
+## Environment Variables
+
+After applying Terraform, configure your applications with these environment variables:
+
+```bash
+# From terraform output
+AWS_REGION=$(terraform output -raw aws_region)
+AWS_S3_BUCKET_NAME=$(terraform output -raw s3_bucket_name)
+AWS_SQS_QUEUE_URL=$(terraform output -raw sqs_queue_url)
+
+# If using RDS
+DATABASE_URL=$(terraform output -raw rds_endpoint)
+
+# If using IAM user (not Fargate)
+AWS_ACCESS_KEY_ID=$(terraform output -raw app_access_key_id)
+AWS_SECRET_ACCESS_KEY=$(terraform output -raw app_secret_access_key)
+```
+
+## CloudWatch Dashboard
+
+The infrastructure creates a comprehensive monitoring dashboard at:
+```
+https://us-east-1.console.aws.amazon.com/cloudwatch/home?region=us-east-1#dashboards:name=meteor-dev-monitoring-dashboard
+```
+
+### Dashboard Includes:
+- **Application metrics**: Request volume, response times, error rates
+- **Business metrics**: Event processing, validation performance
+- **Infrastructure metrics**: SQS queue depth, RDS performance, Fargate utilization
+- **Custom metrics**: From your NestJS and Go services
+
+## Metrics Integration
+
+Your applications are already configured to send metrics to CloudWatch:
+
+### NestJS Web Backend
+- Namespace: `MeteorApp/WebBackend`
+- Metrics: RequestCount, RequestDuration, ErrorCount, AuthOperationCount, etc.
+
+### Go Compute Service  
+- Namespace: `MeteorApp/ComputeService`
+- Metrics: MessageProcessingCount, ValidationCount, DatabaseOperationCount, etc.
+
+## Cost Optimization
+
+### Development Environment
+```hcl
+environment = "dev"
+enable_rds = false                    # Use external database
+enable_fargate = false                # Use external containers
+cloudwatch_log_retention_days = 7     # Shorter retention
+```
+
+### Production Environment
+```hcl
+environment = "prod"
+enable_rds = true
+rds_instance_class = "db.t3.small"    # Appropriate size
+enable_fargate = true                 # High availability
+cloudwatch_log_retention_days = 30    # Longer retention
+```
+

+```
+
+## Deployment Integration
+
+### Docker Compose
+Update your `docker-compose.yml` with Terraform outputs:
+```yaml
+environment:
+  - AWS_REGION=${AWS_REGION}
+  - AWS_S3_BUCKET_NAME=${AWS_S3_BUCKET_NAME}
+  - AWS_SQS_QUEUE_URL=${AWS_SQS_QUEUE_URL}
+```
+
+### GitHub Actions
+```yaml
+- name: Configure AWS credentials
+  uses: aws-actions/configure-aws-credentials@v1
+  with:
+    aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
+    aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
+    aws-region: us-east-1
+
+- name: Deploy infrastructure
+  run: |
+    cd infrastructure
+    terraform init
+    terraform apply -auto-approve
+```
+
+## Security Best Practices
+
+1. **IAM Permissions**: Follow principle of least privilege
+2. **S3 Security**: All buckets have public access blocked
+3. **Encryption**: S3 server-side encryption enabled
+4. **VPC**: Private subnets for database and compute resources
+5. **Secrets**: RDS passwords stored in AWS Secrets Manager
+
+## Monitoring and Alerts
+
+The infrastructure includes CloudWatch alarms for:
+- High error rates in web backend and compute service
+- High response times
+- SQS message age and dead letter queue messages
+- RDS CPU utilization (when enabled)
+
+To add notifications:
+1. Create an SNS topic
+2. Add the topic ARN to alarm actions in `cloudwatch.tf`
+
+## Cleanup
+
+To destroy all resources:
+```bash
+terraform destroy
+```
+
+**Warning**: This will delete all data in S3 and databases. For production, ensure you have backups.
+
+## Troubleshooting
+
+### Common Issues
+
+1. **S3 bucket name conflicts**: Bucket names must be globally unique
+   - Solution: Change `project_name` or `environment` in variables
+
+2. **RDS subnet group errors**: Requires subnets in different AZs
+   - Solution: Ensure `enable_fargate = true` when using RDS
+
+3. **IAM permission errors**: Check AWS credentials and permissions
+   - Solution: Ensure your AWS account has admin access or required permissions
+
+4. **CloudWatch dashboard empty**: Wait for applications to send metrics
+   - Solution: Deploy and run your applications to generate metrics
+
+### Getting Help
+
+1. Check Terraform documentation: https://registry.terraform.io/providers/hashicorp/aws/latest/docs
+2. Review AWS service limits and quotas
+3. Check AWS CloudFormation events for detailed error messages
