## 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
|
|

|
|
|
|
2. **Verify Incrementally**
|
|
- Verify infrastructure before deploying applications
|
|

|
|
- Test each component as it's deployed
|
|
|
|
3. **Monitor Closely**
|
|
- Watch deployment logs
|
|

|
|
- Check for errors immediately
|
|
|
|

## Operations Best Practices
|
|
|
|
### Node Management
|
|
|
|
1. **Validator Management**

|
|
- 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

|
- Update dashboards as needed
|
|
|
|
3. **Log Management**
|
|
