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.

+## Deployment Best Practices
+
+### Pre-Deployment
+
+1. **Review Prerequisites**
+   - Verify all tools are installed and configured
+   - Check Azure quotas and limits
+   - Verify network connectivity
+   - Review [Deployment Checklist](../deployment/DEPLOYMENT_CHECKLIST.md)
+
+2. **Plan Deployment**
+   - Start with canary deployment in single region
+   - Verify canary before full deployment
+   - Plan for rollback if needed
+
+3. **Backup Configuration**
+   - Backup existing configuration
+   - Document current state
+   - Save keys securely
+
+### During Deployment
+
+1. **Use Parallel Deployment**
+   - Use parallel deployment where possible
+   - Monitor deployment progress
+   - Verify each step before proceeding
+
+2. **Verify Incrementally**
+   - Verify infrastructure before deploying applications
+   - Verify applications before deploying contracts
+   - Test each component as it's deployed
+
+3. **Monitor Closely**
+   - Watch deployment logs
+   - Monitor resource usage
+   - Check for errors immediately
+
+### Post-Deployment
+
+1. **Comprehensive Verification**
+   - Verify all services are running
+   - Test RPC endpoints
+   - Verify contract deployments
+   - Check monitoring dashboards
+
+2. **Document Deployment**
+   - Document deployment details
+   - Record contract addresses
+   - Update configuration files
+   - Update documentation
+
+## Operations Best Practices
+
+### Node Management
+
+1. **Validator Management**
+   - Maintain minimum 4 validators
+   - Distribute validators across regions
+   - Monitor validator health continuously
+   - Plan for validator rotation
+
+2. **Scaling**
+   - Scale RPC nodes based on load
+   - Scale sentry nodes for P2P capacity
+   - Never scale validators (consensus requirement)
+
+3. **Updates**
+   - Test updates in staging first
+   - Use rolling updates for non-validators
+   - Coordinate validator updates carefully
+   - Have rollback plan ready
+
+### Monitoring
+
+1. **Set Up Alerts**
+   - Configure critical alerts
+   - Set appropriate thresholds
+   - Test alert channels
+   - Review alerts regularly
+
+2. **Regular Reviews**
+   - Review dashboards daily
+   - Analyze trends weekly
+   - Review alerts monthly
+   - Update dashboards as needed
+
+3. **Log Management**
+   - Centralize logs in Loki
+   - Set appropriate retention
+   - Monitor log volume
+   - Archive old logs
+
+### Backup and Recovery
+
+1. **Regular Backups**
+   - Backup chaindata daily
+   - Backup configuration weekly
+   - Test restore procedures quarterly
+   - Document backup procedures
+
+2. **Disaster Recovery**
+   - Maintain DR runbook
+   - Test DR procedures regularly
+   - Keep backups in multiple locations
+   - Verify backup integrity
+
+## Development Best Practices
+
+### Smart Contract Development
+
+1. **Security First**
+   - Run security scans before deployment
+   - Review all code changes
+   - Test thoroughly
+   - Use established patterns
+
+2. **Testing**
+   - Write unit tests for all contracts
+   - Write integration tests
+   - Use fuzz testing
+   - Test edge cases
+
+3. **Code Quality**
+   - Follow Solidity style guide
+   - Use consistent naming
+   - Document complex logic
+   - Review code before merging
+
+### Integration Development
+
+1. **Error Handling**
+   - Handle all errors gracefully
+   - Provide meaningful error messages
+   - Log errors appropriately
+   - Retry with backoff
+
+2. **Rate Limiting**
+   - Respect rate limits
+   - Implement client-side rate limiting
+   - Handle rate limit errors
