On-Prem Active/Passive Resiliency
Active/Passive resiliency patterns with automatic recovery mechanisms like Kubernetes allow you to accomplish automatic failover without manual intervention in the event of node or VM failure.
Combines With
- Federated Repositories
- Star Pattern
- Ensure you have perfected the Backup/Same-Site Restore pattern before combining it with more advanced patterns like this one
Problems Addressed
- Automatic recovery from application node failure
- Automatic recovery from hardware failure
Prerequisites
- Sonatype Nexus Repository Pro
- Requires external PostgreSQL database
- Resilient and shared blob storage
- Automatic recovery mechanism (e.g., kubernetes)
Factors to Consider
- Recovery Time Objective (RTO) for node failure in minutes
