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.

Complete Quota Analysis and Solutions

Current Quota Status

vCPU Quota

Total Limit: 10 vCPUs
Currently Used: 10 vCPUs (all quota consumed)
Available: 0 vCPUs
System Nodes: 3 × Standard_D2s_v3 = 6 vCPUs
Other Usage: 4 vCPUs (likely other resources or temporary holds)

AKS VM Size Restrictions

Restricted Sizes

❌ Standard_B1s: 1 vCPU, 1GB RAM - Too small
❌ Standard_B1ms: 1 vCPU, 2GB RAM - Too small
⚠️ Standard_B2s: 2 vCPUs, 4GB RAM - AKS-compatible but quota exhausted

Allowed Sizes (When Quota Available)

✅ Standard_B2s: 2 vCPUs, 4GB RAM - Minimum for AKS
✅ Standard_B2ms: 2 vCPUs, 8GB RAM - Better performance
✅ Standard_D2s_v3: 2 vCPUs, 8GB RAM - Production recommended

Solutions

Solution 1: Deploy as Pods (No Quota Needed) ✅ RECOMMENDED

Deploy Besu validators as Kubernetes pods on existing system nodes:

Advantages:

No additional quota needed
Can deploy immediately
Uses existing node capacity
Cost-effective (no new VMs)

Implementation:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: besu-validator
  namespace: besu-network
spec:
  replicas: 1
  selector:
    matchLabels:
      app: besu-validator
  template:
    metadata:
      labels:
        app: besu-validator
    spec:
      nodeSelector:
        pool: system  # Use existing system nodes
      containers:
      - name: besu
        image: hyperledger/besu:latest
        resources:
          requests:
            cpu: 500m
            memory: 2Gi
          limits:
            cpu: 1000m
            memory: 4Gi

Solution 2: Request Quota Increase

Request additional vCPUs from Azure:

Steps:

Check current quota: az vm list-usage --location westeurope
Request increase via Azure Portal
Wait for approval (typically 24-48 hours)
Deploy new node pool after quota increase

Recommended Request:

Request 2-4 additional vCPUs
Allows deployment of 1-2 validator nodes
Provides buffer for future scaling

Solution 3: Use Different Region

Deploy to a region with available quota:

Considerations:

Data sovereignty requirements
Latency implications
Cost differences
Region availability

Recommended Approach

Immediate (No Quota Needed)

Deploy Besu validators as pods on existing nodes
- Uses existing 6 vCPUs from system nodes
- No additional quota required
- Can deploy immediately
Deploy monitoring stack
- Prometheus and Grafana as pods
- Lightweight, runs on existing nodes

Short-term (Request Quota Increase)

Request vCPU quota increase
- Request 2-4 additional vCPUs
- Enables dedicated validator node pool
Deploy validator node pool
- 1-2 nodes × Standard_B2s (2 vCPUs each)
- Dedicated resources for validators

Long-term (Optimize Configuration)

Scale up after validation
- Upgrade to Standard_B2ms or Standard_D2s_v3
- Add more validators for fault tolerance
- Deploy sentries and RPC nodes

Configuration Summary

Current Configuration

System: 3 × Standard_D2s_v3 (2 vCPUs, 8GB RAM) = 6 vCPUs
Quota Used: 10/10 vCPUs (100%)
Available: 0 vCPUs

Proposed Configuration (Pods)

System: 3 × Standard_D2s_v3 (2 vCPUs, 8GB RAM) = 6 vCPUs
Besu Validators: 1-2 pods on system nodes (0 additional quota)
Total: 6 vCPUs (within 10 limit)

Proposed Configuration (After Quota Increase)

System: 3 × Standard_D2s_v3 (2 vCPUs, 8GB RAM) = 6 vCPUs
Validators: 1-2 × Standard_B2s (2 vCPUs, 4GB RAM) = 2-4 vCPUs
Total: 8-10 vCPUs (within 12-14 limit after increase)

Next Steps
