|Work with the Eucalyptus Management Console / Work with IAM|
Roles are used to temporarily allow users or services to access resources without sharing long-term security credentials. Permissions are applied to roles so they not attached to any IAM user or group, allowing applications or services (like Euca2ools) to assume a role that allows them to make programmatic requests to Eucalyptus.
Add the details of your new role:
You can also optionally give the role a path that you define to identify which part of the organization it belongs to.
