Accessing AWS SDK from on-prem server without secret key and access key

Hi,

The AWS IAM Roles Anywhere were designed exactly for that purpose:

You can use AWS Identity and Access Management Roles Anywhere to obtain
 temporary security credentials in IAM for workloads such as servers, containers, 
and applications that run outside of AWS. Your workloads can use the same IAM policies
 and IAM roles that you use with AWS applications to access AWS resources. Using IAM Roles 
Anywhere means you don't need to manage long-term credentials for workloads running 
outside of AWS.

See https://docs.aws.amazon.com/rolesanywhere/latest/userguide/introduction.html

Best,

Didier

The recommended way of doing this is to use AWS Roles Anywhere.
