> There's a new credential provider in the AWS SDK, 
> {{com.amazonaws.auth.EC2ContainerCredentialsProviderWrapper}}
>  this is designed to work within AWS containers as well as EC2 VMs, using env 
> vars to find container credentials first, falling back to the IAM metadata 
> service. This way, when deployed in a container or EC2 VM, it will always 
> find the session credentials for the deployed IAM Role
