### 6. Logging and Monitoring
**CloudWatch Logs:**
- Log group: `/ecs/[stack-name]-litellm`
- Retention: 7 days (configurable)
- Logs from all ECS tasks
**CloudWatch Metrics:**
- ECS: CPU, Memory, Task Count
- ALB: Request Count, Latency, Target Health
- RDS: Connections, CPU, Storage
**Custom Metrics:**
- LiteLLM reports overhead in `x-litellm-overhead-duration-ms` header
- Can be extracted and sent to CloudWatch
## Data Flow
### Request Flow
1. **Client Request**
```
Client → ALB (port 80/443)
```
2. **Load Balancing**
```
ALB → Target Group → Healthy ECS Tasks
```
- ALB selects a healthy task using round-robin
- Sticky sessions not enabled (stateless)
3. **LiteLLM Processing**
```
ECS Task → LiteLLM Proxy (4 workers)
```
- Request handled by one of 4 workers
- Worker selection by internal load balancing (Uvicorn)
4. **Database Operations**
```
LiteLLM → RDS PostgreSQL
```
- Validate API key
- Log request
- Retrieve model configuration
5. **External LLM Call**
```
LiteLLM → External LLM Provider (OpenAI, Anthropic, etc.)
```
- Transform request to provider format
- Forward request via NAT Gateway
- Receive and transform response
6. **Response Flow**
```
LiteLLM → ALB → Client
```
- Response sent back through ALB
- Overhead metrics in headers
### Database Connection Pooling
```
┌──────────────────────────────────────────────┐
│ 4 ECS Tasks × 4 Workers = 16 Workers │
│ │
│ Each Worker → Connection Pool │
│ Pool size: ~10 connections per worker │
│ Total connections: ~160 │
│ │
│ RDS max_connections: 200 │
│ Available headroom: 40 connections │
└──────────────────────────────────────────────┘
```
## High Availability
### Availability Zones
- Resources deployed across 2 AZs
- ECS tasks distributed automatically
- RDS can be configured for Multi-AZ
- ALB spans both AZs
### Failure Scenarios
**Single ECS Task Failure:**
- ALB marks task unhealthy
- Traffic routed to other tasks
- ECS starts replacement task
- Impact: 25% capacity reduction (temporary)
**Availability Zone Failure:**
- ALB routes all traffic to healthy AZ
- ECS maintains tasks in remaining AZ
- Impact: 50% capacity reduction (until AZ recovers)
**Database Failure:**
- With Multi-AZ: Automatic failover to standby (~60-120s)
- Without Multi-AZ: Manual restore from backup
### Recovery Time Objectives
| Scenario | RTO | RPO |
|----------|-----|-----|
| Single task failure | < 2 minutes | None (stateless) |
| AZ failure | < 1 minute | None (stateless) |
| Database failure (Multi-AZ) | < 2 minutes | ~0 (sync replication) |
| Database failure (Single-AZ) | 30-60 minutes | ~5 minutes (backup) |
| Complete region failure | Hours | Depends on backup strategy |
## Scaling
### Horizontal Scaling (Task Count)
**Manual Scaling:**
```bash
aws ecs update-service \
--cluster [cluster-name] \
--service [service-name] \
--desired-count 8
```
**Auto Scaling (CPU-based):**
- Scale out: When average CPU > 70%
- Scale in: When average CPU < 30%
- Min tasks: 2
- Max tasks: 10
**Expected Performance by Scale:**
| Tasks | Workers | Expected RPS | Median Latency |
|-------|---------|--------------|----------------|
| 2 | 8 | ~1,035 | ~200ms |
| 4 | 16 | ~1,170 | ~100ms |
| 8 | 32 | ~2,000+ | ~50-75ms |
### Vertical Scaling (Task Size)
**Upgrade to 8 vCPU, 16 GB:**
```yaml
TaskCPU: 8192
TaskMemory: 16384
```
**Benefits:**
- More workers per task (8-16 workers)
- Better performance per task
- Fewer tasks needed for same throughput
### Database Scaling
**Vertical Scaling:**
- Upgrade to db.r6g.large (2 vCPU → 8 vCPU)
- Minimal downtime (~1-2 minutes)
**Read Replicas:**
- Offload read queries
- Reduce primary load
- Not needed for typical LiteLLM workload
## Cost Optimization
### Reserved Capacity
**ECS Fargate Savings Plans:**
- 1-year: ~20-30% savings
- 3-year: ~40-50% savings
- Applies to Fargate compute usage
**RDS Reserved Instances:**
- 1-year: ~30% savings
- 3-year: ~60% savings
- Partial or full upfront payment
### Right-Sizing
**Monitor and adjust:**
- Use CloudWatch to track actual CPU/Memory usage
- Scale down if consistently under 50% utilization
- Scale up if consistently over 80% utilization
### Alternative Configurations
**Lower Cost (Dev/Test):**
- 2 tasks × 2 vCPU × 4 GB
- db.t3.micro
- Single AZ
- Cost: ~$150-200/month
**Production (HA + Performance):**
- 8 tasks × 4 vCPU × 8 GB
- db.r6g.large (Multi-AZ)
- Redis cluster
- Cost: ~$1,200-1,500/month
## Security Best Practices
### Network Security
- ✅ ECS tasks in private subnets
- ✅ Database not publicly accessible
- ✅ Security groups with principle of least privilege
- ✅ NAT Gateway for controlled outbound access
- ⚠️ Consider VPC endpoints for AWS services (S3, Secrets Manager)
### Authentication & Authorization
- ✅ Master key stored in Secrets Manager
- ✅ IAM roles for task execution
- ✅ IAM roles for task operations
- ⚠️ Implement key rotation policy
- ⚠️ Use IAM-based database authentication
### Data Protection
- ✅ RDS encryption at rest

```bash
cd terraform-ecs
# Initialize Terraform
terraform init
# Review the plan
terraform plan \
-var="db_password=YourSecureDBPassword123" \
-var="master_key=YourSecureMasterKey1234567890"
# Deploy
terraform apply \
-var="db_password=YourSecureDBPassword123" \
-var="master_key=YourSecureMasterKey1234567890"
# Get outputs
terraform output load_balancer_url
terraform output api_endpoint
```
## Testing Your Deployment
### 1. Health Check
```bash
LOAD_BALANCER_URL=$(aws cloudformation describe-stacks \
--stack-name $STACK_NAME \
--query 'Stacks[0].Outputs[?OutputKey==`LoadBalancerURL`].OutputValue' \
--output text)
curl $LOAD_BALANCER_URL/health/readiness
```
### 2. API Test
```bash
# Get your Master Key (if you forgot it)
MASTER_KEY=$(aws secretsmanager get-secret-value \
--secret-id $STACK_NAME-master-key \
--query SecretString \
--output text)
# Test the API
curl -X POST "$LOAD_BALANCER_URL/v1/chat/completions" \
-H "Authorization: Bearer $MASTER_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "fake-openai-endpoint",
"messages": [{"role": "user", "content": "Hello"}]
}'
```
### 3. Load Testing (Benchmark Replication)
To replicate the benchmark results, use Locust:
```bash
# Install Locust
pip install locust
# Create a locustfile (see examples below)
# Run load test with benchmark parameters
locust -f locustfile.py \
--host=$LOAD_BALANCER_URL \
--users=1000 \
--spawn-rate=500 \
--run-time=5m \
--headless
```
**Example Locustfile:**
```python
from locust import HttpUser, task, between
import os
class LiteLLMUser(HttpUser):
wait_time = between(0.1, 0.5)
def on_start(self):
self.master_key = os.environ.get("LITELLM_MASTER_KEY")
@task
def chat_completion(self):
self.client.post("/v1/chat/completions",
headers={
"Authorization": f"Bearer {self.master_key}",
"Content-Type": "application/json"
},
json={
"model": "fake-openai-endpoint",
"messages": [{"role": "user", "content": "test"}]
}
)
```
## Configuration
### Default Parameters
| Parameter | Default | Description |
|-----------|---------|-------------|
| DesiredTaskCount | 4 | Number of ECS tasks (instances) |
| NumWorkersPerTask | 4 | Workers per task |
| TaskCPU | 4096 | CPU units per task (4 vCPU) |
| TaskMemory | 8192 | Memory in MB per task (8 GB) |
| DBInstanceClass | db.t3.medium | RDS instance type |
### Modifying for Different Scales
**For 2 instances (reference configuration):**
```bash
--parameters \
ParameterKey=DesiredTaskCount,ParameterValue=2 \
ParameterKey=NumWorkersPerTask,ParameterValue=4
```
**For higher throughput (8 instances):**
```bash
--parameters \
ParameterKey=DesiredTaskCount,ParameterValue=8 \
ParameterKey=NumWorkersPerTask,ParameterValue=4
```
**For more powerful instances:**
```bash
--parameters \
ParameterKey=TaskCPU,ParameterValue=8192 \
ParameterKey=TaskMemory,ParameterValue=16384
```
## Monitoring
### CloudWatch Logs
View logs from your ECS tasks:
```bash
aws logs tail /ecs/$STACK_NAME-litellm --follow
```
### CloudWatch Metrics
Key metrics to monitor:
- **ECS:** CPUUtilization, MemoryUtilization
- **ALB:** TargetResponseTime, RequestCount, HealthyHostCount
- **RDS:** DatabaseConnections, CPUUtilization, FreeableMemory
### LiteLLM Overhead Monitoring
LiteLLM reports its overhead in the `x-litellm-overhead-duration-ms` response header. Monitor this to track proxy performance.
## Cost Estimation
**Monthly costs (us-east-1, approximate):**
| Resource | Configuration | Monthly Cost |
|----------|---------------|--------------|
| ECS Fargate | 4 tasks × 4 vCPU × 8 GB | ~$350 |
| RDS PostgreSQL | db.t3.medium, 100 GB | ~$60 |
| Application Load Balancer | 1 ALB | ~$20 |
| Data Transfer | Varies by usage | ~$10-50 |
| **Total** | | **~$440-460/month** |
**Cost optimization tips:**
- Use Reserved Instances or Savings Plans for ECS Fargate (up to 50% savings)
- Enable RDS auto-scaling for storage
- Use AWS Cost Explorer to track actual costs
- Consider smaller instance types for non-production environments
## Cleanup
To delete all resources:
```bash
aws cloudformation delete-stack --stack-name $STACK_NAME
```
## Troubleshooting
### Tasks not starting
1. Check ECS service events:
```bash
aws ecs describe-services \
--cluster $STACK_NAME-LiteLLM-Cluster \
--services $STACK_NAME-litellm-service \
--query 'services[0].events[0:5]'
```
2. Check task logs:
```bash
aws logs tail /ecs/$STACK_NAME-litellm --follow
```
### Database connection issues
1. Verify RDS is running:
```bash
aws rds describe-db-instances \
--db-instance-identifier $STACK_NAME-litellm-db \
--query 'DBInstances[0].DBInstanceStatus'
```
2. Check security group rules allow ECS → RDS communication
### High latency
1. Check if you have enough tasks running:
```bash
aws ecs describe-services \
--cluster $STACK_NAME-LiteLLM-Cluster \
--services $STACK_NAME-litellm-service \
--query 'services[0].[runningCount,desiredCount]'
```
2. Monitor RDS performance in CloudWatch
3. Consider scaling up task count or RDS instance size
## Advanced Configuration
### Adding Redis Cache
Redis can reduce database load by 60-80%. To add Redis:
1. Add ElastiCache Redis cluster to the CloudFormation template
2. Update task environment variables:
```yaml
- Name: REDIS_HOST
Value: !GetAtt RedisCluster.RedisEndpoint.Address
- Name: REDIS_PORT
Value: 6379
```
3. Update proxy config to enable caching
### Custom Domain with HTTPS
1. Create an SSL certificate in AWS Certificate Manager
2. Add HTTPS listener to the ALB:
```bash
aws elbv2 create-listener \
--load-balancer-arn <ALB-ARN> \
--protocol HTTPS \
--port 443 \
--certificates CertificateArn=<CERT-ARN> \
--default-actions Type=forward,TargetGroupArn=<TG-ARN>
```
3. Update Route53 DNS to point to the ALB
### Auto-scaling
Enable ECS Service Auto Scaling based on CPU or request metrics:
```bash
aws application-autoscaling register-scalable-target \
--service-namespace ecs \
--scalable-dimension ecs:service:DesiredCount \
--resource-id service/$STACK_NAME-LiteLLM-Cluster/$STACK_NAME-litellm-service \
--min-capacity 2 \
--max-capacity 10
aws application-autoscaling put-scaling-policy \
--service-namespace ecs \
--scalable-dimension ecs:service:DesiredCount \
--resource-id service/$STACK_NAME-LiteLLM-Cluster/$STACK_NAME-litellm-service \
--policy-name cpu-scaling \
--policy-type TargetTrackingScaling \
