Starting point of my e-commerce AWS project

There are also the AWS Cloud Foundations, which provide you prescriptive guidance on best practices that you can implement when setting up a new AWS environment (incl. multiple accounts).

But before jumping at any of the resources that were provided, you may think about what it is that you're trying to achieve. If you're developing an e-Commerce application from scratch, then you should put a special focus on the CI/CD and general developer experience, as that is were you will spend a lot of time and resources at, so this should be optimized for maximum productivity and cost efficiency. Our Developer Tools page provides a great overview of services that will come in handy for this. If there are other developers participating in the project as well, maybe also have a look at CodeCatalyst as that can significantly simplify the development process.

On the other hand, if this is project where you're implementing an off-the-shelf e-Commerce system such as Wordpress or Magento for a customer, there are other areas that you may focus on. In such a case, the developer experience may not be as important as things like Monitoring and Observability, and how to ensure that the production systems runs in a scalable, highly-availabile and cost-effective manner. Here, the Well-Architected Framework provides a lot of relevant information that you will certainly find useful.
