Connecting to AWS

There are 3 options when connecting to AWS:

1. An AWS instance profile or pod identity (the default if no connection or accessKey is specified)

2. connection, this is the recommended method, connections are reusable and secure

     cloudwatch:
       - connection: connection://aws/internal
         region: us-east-1 # optional if specified in the connection

3. accessKey and secretKey EnvVar with the credentials stored in a secret.
