-- | Suspends the specified Auto Scaling processes for the specified Auto Scaling
-- group. To suspend specific processes, use the 'ScalingProcesses' parameter. To
-- suspend all processes, omit the 'ScalingProcesses' parameter.
--
-- Note that if you suspend either the 'Launch' or 'Terminate' process types, it
-- can prevent other process types from functioning properly.
--
-- To resume processes that have been suspended, use 'ResumeProcesses'.
--
-- For more information, see <http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/US_SuspendResume.html Suspend and Resume Auto Scaling Processes> in the /Auto Scaling Developer Guide/.
