launch - EC2 Fleet launches a replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet.

You are charged for all instances while they are running.

launch-before-terminate - EC2 Fleet launches a replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet, and then, after a delay that you specify (in TerminationDelay), terminates the instances that received a rebalance notification.

Optional TerminationDelay

TerminationDelay: undefined | number

The amount of time (in seconds) that Amazon EC2 waits before terminating the old Spot Instance after launching a new replacement Spot Instance.

Required when ReplacementStrategy is set to launch-before-terminate.

Not valid when ReplacementStrategy is set to launch.

Valid values: Minimum value of 120 seconds. Maximum value of 7200 seconds.
