It has lots of modules that makes our lives easier. As a heavy-user of ansible for infrastructure provisioning on AWS, I sometimes get frustrated to have to deal with different data structures used by modules.

One example I had to deal with recently was the tags attribute of ec2_asg and ec2_tag. You cannot just pass the same value for both of them because ec2_asg tags attribute expects a list of dicts, while ec2_tag expects just a dict. That difference is because ec2_asg’s dicts have an optional attribute called propagate_at_launch.
