On-Prem Active/Passive Resiliency
 |
Active/Passiveresiliency 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
Ensure you have perfected the Backup/Same-Site Restore pattern before combining it with more advanced patterns like this one
