Ansible, an open-source automation tool, has become a staple in the world of IT automation, enabling organizations to manage and configure their systems with ease. Two prominent offerings in the Ansible ecosystem are Ansible AWX and Ansible Tower. While both serve the same fundamental purpose, there are notable differences between them.
