Types of Redundancies Supported
SMF supports following types of redundancies:
Redundancy Type |
Description |
---|---|
Server |
The solution is designed to sustain server failures and distribute the workload to another server in the cluster. In this scenario, most of the essential and service critical pods are running in Active and Standby modes, and they reside on a different server to cause minimum impact in the event of a hardware failure. |
Rack |
In this scenario, the Kubernetes cluster is mirrored in the same Data Center, but on different racks. In case of multiple server failures, software failures, or an adjacent routing layer issue, the sessions are switched to other racks. This way, it is assured to achieve the same level of service from the new rack. |
Site |
In this scenario, the Kubernetes cluster is mirrored in different geographical data centers. In case of a whole data center is downtime, the sessions are switched to the other rack in a different data center. Through this, it is assured to achieve the same level of service from the new rack. |
