You are using lifecycle hooks in your AutoScaling Group.

Because there is a lifecycle hook, the instance is put in the Pending:Wait state, which means that it is not available to handle traffic yet.

When the instance enters the wait state, other scaling actions are suspended.

After some time, the instance state is changed to Pending:Proceed, and finally InService where the instances that are part of the Autoscaling Group can start serving up traffic.

But you notice that the bootstrapping process on the instances finishes much earlier, long before the state is changed to Pending:Proceed.
