My question title may not appropriate as I am not so aware of how to call it. I will appreciate it if anyone can edit to fits the query.

I am planning to build a web application where users will subscribe. For instance, CRM or Project management application. I want to have a separate instance and database with a custom domain for enterprise subscribers, and I may have a common database or instance for non-enterprise subscribers. The subscription will be handled through a marketing website, where all subscribers will checkout and have their own account.

• Marketing website to subscribe
• Application instance / website/ database / etc

Once the subscription period is over and it is not renewed, they will lose access. If they do not renew/reactivate for x time, the instance will destroy itself.

I am quite confident with PHP and MySQL, have some knowledge of *AWS** and Digital Ocean. I am planning to use Laravel for serverside. However, I am open to other languages as well, such as python.`*

Can anyone help me to learn the best approach for the system I want to
make. Pros and Cons and things to be considered? Also, approach to make a mobile application for the subscriber where they can access their own instance.
