Help with making a UDP stream highly available and fault-tolerant from the data center to a cloud Linux server?

I have a data center which can receive two identical UDP streams from a multicast connection. I want to transfer that feed to an AWS instance. How can I make sure that my feed is highly available and fault tolerant?

Is there a way using which I can forward stream 1 to the cloud linux box and if due to some interference or some other reason stream 1 is not available I can forward the identical stream 2 instead to the same cloud linux box on the same port. Just like in a router when 1 switch fails the other automatically takes over. In the same way is there something that can be done with those two identical streams so that my cloud linux server can receive highly available UDP stream?
