High Availability Skupper router

When you create a site you can specify the number of Skupper routers provisioned, for example skupper init --routers 2. This can seem an attractive option, to ensure that traffic flows even if a Skupper router fails. However, there is no guarantee that traffic flow is balanced across the routers and the traffic flow distribution might be unexpected. NOTE: The high availability discussed here is not related to exposed traffic load balancing and failover, which is described in .

Skupper recommends increasing memory and CPU allocation to the Skupper router, rather than the number of Skupper routers to maximise resiliency.

What if --routers was changed to something like --ha-replication?

as a user I'd want to attach these to specific network devices to really get ha?
ATM the option is descriptive of what happens, in the future we should harness the power of kubernetes/linux, maybe be more generic but more powerful.
