High Availability Inside Rack

High availability inside rack is an arrangement that handles server level redundancies. In this solution, in case of a single server failure, a few pods according to the design might get distributed in another available server. Meanwhile, other pods remain in pending state until the server comes back.

In this scenario, the critical pods that handle the external traffic run on Active-Stand-by pair on a different server. The redundancy support in the routing layer is provided by leaf and spine layers.
