Security in Amazon Stages

You can configure Amazon stages to use one of the following authentication methods to connect securely to Amazon Web Services (AWS):

Instance profile: When the execution Data Collector runs on an Amazon EC2 instance that has an associated instance profile, Data Collector uses the instance profile credentials to automatically authenticate with AWS.; For more information about associating an instance profile with an EC2 instance, see the Amazon EC2 documentation.
AWS access keys: When the execution Data Collector does not run on an Amazon EC2 instance or when the EC2 instance doesn’t have an instance profile, you can authenticate using an AWS access key pair. When using an AWS access key pair, you specify the access key ID and secret access key to use.

Note: When configuring an Amazon S3 stage or an Amazon SQS Consumer origin to access a public bucket, you can also configure the stage to connect anonymously using no authentication.
