# Quota Optimization Plan
|
||
|
||
## Current Quota Status
|
||
|
||
### vCPU Quota
|
||
- **Total Limit**: 10 vCPUs
|
||
- **Currently Used**: 6 vCPUs (3 nodes × Standard_D2s_v3 @ 2 vCPUs each)
|
||
- **Available**: 4 vCPUs
|
||
|
||
## Optimization Strategy
|
||
|
||
### Option 1: Use 1 vCPU VMs (Recommended)
|
||
**VM Size**: `Standard_B1ms` (1 vCPU, 2GB RAM)
|
||
|
||
**Configuration**:
|
||
- System: 1 node × 1 vCPU = 1 vCPU
|
||
- Validators: 2 nodes × 1 vCPU = 2 vCPUs
|
||
- Sentries: 1 node × 1 vCPU = 1 vCPU
|
||
- RPC: 1 node × 1 vCPU = 1 vCPU
|
||
- **Total New**: 5 vCPUs
|
||
- **Current**: 6 vCPUs
|
||
- **Combined**: 11 vCPUs (exceeds quota by 1)
|
||
|
||
**Solution**: Reduce system pool or keep existing and add only validators
|
||
|
||
### Option 2: Keep Existing + Add Minimal (Best Fit)
|
||
**Keep**: 3 nodes × Standard_D2s_v3 = 6 vCPUs
|
||
**Add**: 2 validators × Standard_B1ms = 2 vCPUs
|
||
**Total**: 8 vCPUs (within 10 vCPU limit)
|
||
|
||
### Option 3: Replace with Smaller VMs
|
||
**Replace**: 3 × Standard_D2s_v3 (6 vCPUs) with 3 × Standard_B1ms (3 vCPUs)
|
||
**Add**: 2 validators × Standard_B1ms (2 vCPUs)
|
||
**Total**: 5 vCPUs (well within limit, saves 5 vCPUs)
|
||
|
||
## Recommended Approach
|
||
|
||
### Phase 1: Add Validators Only (Fits Current Quota)
|
||
```hcl
|
||
node_count = {
|
||
system = 3 # Keep existing
|
||
validators = 2 # Add 2 × 1 vCPU = 2 vCPUs (fits in 4 available)
|
||
sentries = 0 # Defer
|
||
rpc = 0 # Defer
|
||
}
|
||
|
||
vm_size = {
|
||
system = "Standard_D2s_v3" # Keep existing
|
||
validators = "Standard_B1ms" # 1 vCPU, 2GB RAM
|
||
sentries = "Standard_B1ms"
|
||
rpc = "Standard_B1ms"
|
||
}
|
||
```
|
||
|
||
### Phase 2: After Quota Increase
|
||
Add sentries and RPC nodes with larger VMs
|
||
|
||
## Available VM Sizes (1-2 vCPUs)
|
||
|
||
### Burstable (B-series) - Best for Cost
|
||
- **Standard_B1s**: 1 vCPU, 1GB RAM - $0.0052/hour
|
||
- **Standard_B1ms**: 1 vCPU, 2GB RAM - $0.0104/hour
|
||
- **Standard_B2s**: 2 vCPUs, 4GB RAM - $0.0208/hour
|
||
|
||
### General Purpose (D-series)
|
||
- **Standard_D2s_v3**: 2 vCPUs, 8GB RAM - $0.096/hour (current)
|
||
- **Standard_D1s_v3**: 1 vCPU, 4GB RAM - $0.048/hour
|
||
|
||
### Memory Optimized
|
||
- **Standard_E2s_v3**: 2 vCPUs, 16GB RAM - $0.134/hour
|
||
|
||
## Cost Comparison
|
||
|
||
### Current Configuration
|
||
- 3 × Standard_D2s_v3 = $0.288/hour = ~$210/month
|
||
|
||
### Optimized Configuration (Option 3)
|
||
- 3 × Standard_B1ms = $0.0312/hour = ~$23/month
|
||
- 2 × Standard_B1ms (validators) = $0.0208/hour = ~$15/month
|
||
- **Total**: ~$38/month (82% cost savings)
|
||
|
||
## Implementation Steps
|
||
|
||
1. **Review quotas**: ✅ Done
|
||
2. **Select VM sizes**: Standard_B1ms for new nodes
|
||
3. **Update terraform.tfvars**: Use quota-optimized config
|
||
4. **Deploy validators first**: 2 nodes × 1 vCPU = 2 vCPUs
|
||
5. **Monitor performance**: Ensure B-series burst credits sufficient
|
||
6. **Scale up later**: After quota increase or performance validation
|
||
|
||
## Notes
|
||
|
||
- **B-series VMs**: Have CPU credits, good for variable workloads
|
||
- **Minimum for Besu**: 1 vCPU, 2GB RAM (Standard_B1ms)
|
||
- **Production recommendation**: Standard_B2s or larger for validators
|
||
- **Current approach**: Use B1ms for development/testing, upgrade later
