## 🎯 Common Workflows

### 1. Deploy and Test

```bash

# Wait for completion (script handles this)

# Test deployment
./test-deployment.sh

# Run benchmark
export LITELLM_MASTER_KEY="your-master-key"
export LITELLM_HOST="http://your-alb-url"
pip install locust
locust -f locustfile.py --users=1000 --spawn-rate=500 --run-time=5m --headless
```

### 2. Estimate Costs

```bash
# Calculate costs before deploying
./cost-calculator.sh

# Enter your configuration:
# - Number of tasks: 4
# - vCPU per task: 4
# - Memory per task: 8
# - RDS instance: t3.medium
```

### 3. Customize Configuration

```bash
# 1. Copy example config
cp example-config.yaml my-config.yaml

# 2. Edit with your API keys and settings
nano my-config.yaml

# 3. Update CloudFormation template to mount config
# (See README.md for detailed instructions)

# 4. Redeploy
aws cloudformation update-stack ...
```

### 4. Scale Your Deployment

```bash
# Scale to 8 tasks
aws ecs update-service \
  --cluster litellm-benchmark-LiteLLM-Cluster \
  --service litellm-benchmark-litellm-service \
  --desired-count 8

# Or redeploy with new parameters
DESIRED_TASKS=8 ./deploy.sh
```

### 5. Monitor and Troubleshoot

```bash
# View logs
aws logs tail /ecs/litellm-benchmark-litellm --follow

# Check service status
aws ecs describe-services \
  --cluster litellm-benchmark-LiteLLM-Cluster \
  --services litellm-benchmark-litellm-service

# View CloudWatch metrics
# Go to CloudWatch Console → Metrics → ECS/RDS/ALB
```

### 6. Cleanup

```bash
# Delete entire stack
aws cloudformation delete-stack --stack-name litellm-benchmark

# Verify deletion
aws cloudformation describe-stacks --stack-name litellm-benchmark
```

Application Load Balancer (Public)
   ↓
ECS Tasks (Private) × 4
   └─ 4 vCPU, 8 GB RAM, 4 workers each
   ↓
RDS PostgreSQL (Private)
   └─ db.t3.medium, 100 GB
```

**Security:**

## 📈 Performance Benchmarks

### Benchmark Test Results

Using Locust with 1,000 concurrent users:

| Metric | 2 Instances | 4 Instances (Target) |
|--------|-------------|----------------------|
| Median Latency | 200 ms | **100 ms** |
| P95 Latency | 630 ms | **150 ms** |
| P99 Latency | 1,200 ms | **240 ms** |
| Average Latency | 262 ms | **111.7 ms** |
| Throughput | 1,035 RPS | **1,170 RPS** |
| LiteLLM Overhead | 12 ms | **2 ms** |

**Key Finding:** Doubling instances from 2 to 4 halves median latency.
