We use it based on automation. We can create new customers or entities and automatically apply specific configurations according to predefined rules. This automation is a key feature of Control Tower. Additionally, Control Tower can be scripted to automate these processes further. Although not directly related, the combination of AWS Management and Control Tower simplifies accounts' management and billing structure. One notable advantage is the separation between account structure management and account billing. For instance, it allows us to use a centralized billing system and centralized account management, which is highly beneficial. It has become very central and essential. Without Control Tower, for instance, we couldn't automate the creation of thousands of environments across the company, but with it, we can. You need to be a good AWS architect. It requires more skill than just being a practitioner. Ideally, you should be an architect and have an AWS Certification. Overall, I rate the solution a nine out of ten.
