Connect to Amazon EC2 instance from ios app

I am trying to make an ios application that uses Amazon Web Services as its backend. I have a MySQL database in RDS and you want to query this database from the application in order to get the content for the application. After some research, it seems like I should approach this by adding my own API to query the database for an EC2 instance. Then, instead of directly accessing the RDS instance from the application, I access the API on the EC2 instance, which accesses the RDS instance for me. First, is that the way? I am also open to other suggestions.

Here is what I have done so far by reading this post:

  • Installed apache and php for my EC2 instance.
  • Got an elastic IP for my EC2 instance.
  • Added a file (call it retrieve-data.php) in apache, which uses my endpoint, username and password for RDS to query the database and return data.

In my ios application, I can send elastic_ip_address_of_my_ec2_instance / retrieve-data.php http request to get data from my RDS database in my application. Is that the way? Could this be improved in any way?
