The Developer support plan is the correct choice because it is the lowest paid tier that provides business hours email access to AWS Cloud Support Associates and it does not include phone or chat.

The Developer plan is designed for early stage or nonproduction use and it offers technical case submission by email during business hours with Cloud Support Associates. This matches Aurora Pixel requirements by limiting access to email only and by avoiding the higher cost and expanded channels of phone and chat support.

The Basic plan is free but it does not include technical case support by email so it cannot meet the requirement to open cases with Cloud Support Associates.

The Business plan includes 24x7 phone chat and email access to Cloud Support Engineers which is more than requested and it is a higher cost option than the Developer plan.

The Enterprise plan also provides 24x7 phone chat and email and it adds advanced features and account management so it is not the lowest cost fit for the stated needs.
