AWS storage class analysis vs intelligent tiering

Question

0

I understand that AWS storage class analysis allows us to understand the access pattern of object, which can then be used to make decision on life cycle policy configuration

With S3 Intelligent Tiering, why do we need to use this approach? Isn't Intelligent tiering a solution that can get rid of storage class analysis and hassle of setting up life cycle policy configuration? (Apart from probably cost as I understand that other than same cost for storage by class, Intelligent tiering charge an extra of "All Storage / Month $0.0025 per 1,000 objects" for Monitoring and Automation)
