-- | The minimum number of healthy instances that should be available at any
-- time during the deployment. There are two parameters expected in the
-- input: type and value.
--
-- The type parameter takes either of the following values:
--
-- -   HOST_COUNT: The value parameter represents the minimum number of
--     healthy instances, as an absolute value.
-- -   FLEET_PERCENT: The value parameter represents the minimum number of
--     healthy instances, as a percentage of the total number of instances
--     in the deployment. If you specify FLEET_PERCENT, then at the start
--     of the deployment AWS CodeDeploy converts the percentage to the
--     equivalent number of instances and rounds fractional instances up.
--
-- The value parameter takes an integer.
--
-- For example, to set a minimum of 95% healthy instances, specify a type
-- of FLEET_PERCENT and a value of 95.
