REL10-BP03: Automate recovery for components constrained to a single location
Overview
Implement automated recovery mechanisms for workload components that cannot be distributed across multiple locations due to technical, regulatory, or cost constraints. These single-location components represent potential single points of failure and require robust automated recovery strategies to maintain overall system reliability.
Implementation Steps
1. Identify Single-Location Components
- Catalog components constrained to single locations
- Analyze constraints preventing multi-location deployment
- Assess impact and criticality of single-location components
- Document dependencies and recovery requirements
2. Design Automated Recovery Strategies
- Implement automated backup and restore procedures
- Configure rapid provisioning and deployment automation
- Design failover mechanisms within the same location
- Establish automated health monitoring and failure detection
3. Implement Recovery Automation
- Configure automated instance replacement and scaling
- Implement database failover and point-in-time recovery
- Design automated application deployment and configuration
- Establish automated network and load balancer reconfiguration
4. Set Up Monitoring and Alerting
- Configure comprehensive health checks and monitoring
- Implement automated failure detection and classification
- Design escalation procedures and notification systems
- Establish recovery progress tracking and reporting
5. Configure Recovery Testing and Validation
- Implement automated recovery testing procedures
- Configure recovery time objective (RTO) validation
- Design recovery point objective (RPO) verification
- Establish continuous recovery capability assessment
6. Optimize Recovery Performance
- Monitor and analyze recovery times and success rates
- Implement continuous improvement based on recovery metrics
- Optimize recovery procedures and automation
- Establish recovery capacity planning and resource allocation
