-- Registers the specified targets with the specified target group.
--
--
-- You can register targets by instance ID or by IP address. If the target is an EC2 instance, it must be in the @running@ state when you register it.
--
-- By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.
--
-- With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.
--
-- To remove a target from a target group, use 'DeregisterTargets' .
