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.

# Cloud for Sovereignty Landing Zone - Multi-Region Architecture
|
||||
|
||||
## Overview
|
||||
|
||||
This document outlines the Well-Architected Framework implementation for a Cloud for Sovereignty landing zone across all Azure commercial Non-US regions.
|
||||
|
||||
## Architecture Principles
|
||||
|
||||
1. **Data Sovereignty**: Data remains within specified regions
|
||||
2. **Compliance**: Meets regional regulatory requirements
|
||||
3. **Resilience**: Multi-region deployment for high availability
|
||||
4. **Scalability**: Supports growth across regions
|
||||
5. **Cost Optimization**: Efficient resource utilization
|
||||
|
||||

## Resource Organization
|
||||
|
||||
### Per-Region Structure
|
||||
Each region follows the Well-Architected Framework structure:
|
||||
|
||||
```
|
||||
{cloud}-{env}-{region}-rg-{type}-{instance}
|
||||
```
|
||||
|
||||
Example: `az-p-we-rg-comp-001` (Azure, Production, West Europe, Resource Group, Compute, Instance 001)
|
||||
|
||||
### Resource Group Types
|
||||
- **Network** (`rg-net-001`): Virtual networks, subnets, NSGs, Application Gateways
|
||||
- **Compute** (`rg-comp-001`): AKS clusters, VMs, Container Instances
|
||||
- **Storage** (`rg-stor-001`): Storage accounts, backups
|
||||
- **Security** (`rg-sec-001`): Key Vaults, Security Centers
|
||||
- **Monitoring** (`rg-mon-001`): Log Analytics, Application Insights
|
||||
- **Identity** (`rg-id-001`): Managed identities, Azure AD resources
|
||||
- **Terraform State** (`rg-tfstate-001`): State storage
|
||||
|
||||
## Deployment Strategy
|
||||
|
||||
### Phase 1: Foundation
|
||||
1. Management Group hierarchy
|
||||
2. Subscription organization
|
||||
3. Policy definitions and assignments
|
||||
4. Role-based access control (RBAC)
|
||||
|
||||
### Phase 2: Core Infrastructure (Per Region)
|
||||
1. Resource Groups (all types)
|
||||
2. Virtual Networks and connectivity
|
||||
3. Key Vaults
|
||||
4. Log Analytics Workspaces
|
||||
5. Storage accounts
|
||||
|
||||
### Phase 3: Compute Resources (Per Region)
|
||||
1. AKS clusters
|
||||
2. Node pools (validators, sentries, RPC)
|
||||
3. Container registries
|
||||
|
||||
### Phase 4: Application Deployment
|
||||
1. Besu network components
|
||||
2. Monitoring stack

|
||||
|
||||
## Compliance & Sovereignty
|
||||

|
||||
- Regional compliance certifications
|
||||
|
||||
### Security
|
||||
- Regional Key Vaults
|
||||
- Regional identity providers
|
||||

||||
|
||||
## Cost Management
|
||||
|
||||
### Tagging Strategy
|
||||
- Environment: prod, dev, test, staging
|
||||
- Region: region code
|
||||
- CostCenter: Blockchain
|
||||
- Project: DeFi Oracle Meta Mainnet
|
||||
- ManagedBy: Terraform
|
||||
|
||||
### Budgets
|
||||
- Per-region budgets
|
||||
- Per-environment budgets
|
||||
- Alert thresholds
|
||||
|
||||
## Monitoring & Governance
|
||||
|
||||
### Centralized Monitoring
|
||||
- Log Analytics Workspaces per region
|
||||
- Centralized dashboard
|
||||
- Cross-region metrics aggregation
|
||||
|
||||
### Policy Enforcement
|
||||
- Naming conventions
|
||||
- Resource location restrictions
|
||||
- Tag requirements
|
||||
- SKU restrictions
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. Create management group structure
|
||||
2. Create subscription structure
|
||||
3. Deploy foundation resources
|
||||
4. Deploy per-region infrastructure
|
||||
5. Deploy application components
|
||||
6. Configure monitoring and governance
