Just been reading the documentation on a HA cluster setup. I’m planning on running a HA cluster on EC2 instances directly on the host with no docker.
Despite seeing people on the forum run 3 instances in total, with alpha and zero both running on one host, this seems pretty counterproductive as if one instance goes down, you’re jeopardizing the availability of both alpha and zero.
My cluster will consist of:
3 zero instances
3 alpha instances
7 instances in total
From what I can see, you can only point an Alpha at one Zero… if that zero goes down, what happens to that alpha instance? Can it still communicate with the other two Zeros? After connecting to one Zero, does it then get the connection info for all of the Zeros? Should the --zero flag actually be a list of zeros so it can round-robin?
