AWS IAM Role Name considred as Class in Yii 1

This question is related to IAM Role Name considred as Class in Yii 1

As mentioned in the answer there, I unregistered and re-registered YII's autoloader before making any AWS call. And that is removing my issue of failed to open stream: No such file or directory. But writing this same piece of code everywhere I'm making any call to AWS does not seem logical to me.

What are the alternatives to this solution?
