PowerVille LB can be deployed in either standalone or redundant configuration. In a redundant configuration, PowerVille LB actively checkpoints and replicates relevant flow descriptors, such that there is no service disruption in case of device
or power failure.\
In a redundant configuration, PowerVille LB can provide redundancy in case of any individual service node outage as described in the Service Resilience section above. In addition, redundant implementations support geographic distribution of the
underlying service nodes, and can distribute load across distinct geographic locations, helping to avoid large scale outages should a whole data center fail. Redundant PowerVille LB implementations also support automatic disaster recovery functions,
moving flows from one datacenter to another.
