// Describes a process type.
//
// There are two primary Auto Scaling process types--Launch and Terminate.
// The Launch process creates a new EC2 instance for an Auto Scaling group,
// and the Terminate process removes an existing EC2 instance. The remaining
// Auto Scaling process types relate to specific Auto Scaling features:
//
//  AddToLoadBalancer AlarmNotification AZRebalance HealthCheck ReplaceUnhealthy
// ScheduledActions   If you suspend Launch or Terminate, all other process
// types are affected to varying degrees. The following descriptions discuss
// how each process type is affected by a suspension of Launch or Terminate.
//  The AddToLoadBalancer process type adds instances to the load balancer when
// the instances are launched. If you suspend this process, Auto Scaling will
// launch the instances but will not add them to the load balancer. If you resume
// the AddToLoadBalancer process, Auto Scaling will also resume adding new instances
// to the load balancer when they are launched. However, Auto Scaling will not
// add running instances that were launched while the process was suspended;
// those instances must be added manually using the  RegisterInstancesWithLoadBalancer
// (http://docs.aws.amazon.com/ElasticLoadBalancing/latest/APIReference/API_RegisterInstancesWithLoadBalancer.html)
// call.
//
// The AlarmNotification process type accepts notifications from Amazon CloudWatch
// alarms that are associated with the Auto Scaling group. If you suspend the
// AlarmNotification process type, Auto Scaling will not automatically execute
// scaling policies that would be triggered by alarms.
//
// Although the AlarmNotification process type is not directly affected by
// a suspension of Launch or Terminate, alarm notifications are often used to
// signal that a change in the size of the Auto Scaling group is warranted.
// If you suspend Launch or Terminate, Auto Scaling might not be able to implement
// the alarm's associated policy.
//
// The AZRebalance process type seeks to maintain a balanced number of instances
// across Availability Zones within a Region. If you remove an Availability
// Zone from your Auto Scaling group or an Availability Zone otherwise becomes
// unhealthy or unavailable, Auto Scaling launches new instances in an unaffected
// Availability Zone before terminating the unhealthy or unavailable instances.
// When the unhealthy Availability Zone returns to a healthy state, Auto Scaling
// automatically redistributes the application instances evenly across all of
// the designated Availability Zones.
//
//  If you call SuspendProcesses on the launch process type, the AZRebalance
// process will neither launch new instances nor terminate existing instances.
// This is because the AZRebalance process terminates existing instances only
// after launching the replacement instances.
//
// If you call SuspendProcesses on the terminate process type, the AZRebalance
// process can cause your Auto Scaling group to grow up to ten percent larger
// than the maximum size. This is because Auto Scaling allows groups to temporarily
// grow larger than the maximum size during rebalancing activities. If Auto
// Scaling cannot terminate instances, your Auto Scaling group could remain
// up to ten percent larger than the maximum size until you resume the terminate
// process type.
//
//  The HealthCheck process type checks the health of the instances. Auto Scaling
// marks an instance as unhealthy if Amazon EC2 or Elastic Load Balancing informs
// Auto Scaling that the instance is unhealthy. The HealthCheck process can
// override the health status of an instance that you set with SetInstanceHealth.
//
// The ReplaceUnhealthy process type terminates instances that are marked as
// unhealthy and subsequently creates new instances to replace them. This process
// calls both of the primary process types--first Terminate and then Launch.
//
//  The HealthCheck process type works in conjunction with the ReplaceUnhealthly
// process type to provide health check functionality. If you suspend either
// Launch or Terminate, the ReplaceUnhealthy process type will not function
// properly.
//
//  The ScheduledActions process type performs scheduled actions that you create
// with PutScheduledUpdateGroupAction. Scheduled actions often involve launching
// new instances or terminating existing instances. If you suspend either Launch
// or Terminate, your scheduled actions might not function as expected.
