Answer 2

Answer:

Don't save your API credentials. Instead create a role in IAM and assign this role to an EC2 instance when you first create it

Explanation:

If the aim of the web application is to call the S3 API, for proper functioning, there is no need to store the API credentials to maintain a maximum level of security. All you need to do is to create a role in IAM and then assign the created role to an EC instance at the first moment that it was created. This would ensure that the highest level of security, while still achieving the aim of allowing your web application function properly.
