Poor Man's Global Traffic Manager

Sometimes we need to add redundancy to some service or server which happen to be a public-facing entry point of our infrastructure. For example, imagine we want to add a high availability pair for a load balancer which sits on the edge of network and forwards traffic to alive backend servers.

                                             ┌─────────────┐
                                             │             │
                                      ┌─────►│  Backend 1  │
                                      │      │             │
                                      │      └─────────────┘
