defiQUG 1fb7266469 Add Oracle Aggregator and CCIP Integration

- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control.
- Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities.
- Created .gitmodules to include OpenZeppelin contracts as a submodule.
- Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment.
- Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks.
- Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring.
- Created scripts for resource import and usage validation across non-US regions.
- Added tests for CCIP error handling and integration to ensure robust functionality.
- Included various new files and directories for the orchestration portal and deployment scripts.

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)

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

Review quotas: ✅ Done
Select VM sizes: Standard_B1ms for new nodes
Update terraform.tfvars: Use quota-optimized config
Deploy validators first: 2 nodes × 1 vCPU = 2 vCPUs
Monitor performance: Ensure B-series burst credits sufficient
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
