While Grid and Cloud environments provide the opportunity extending own local resources with external resources the connection to this additional resources often is not available in both directions.
A reason for this often being restrictions imposed by the firewall policy of an organisation. Thus, while it is in general possible to submit an application to Grid or Cloud resources from the intranet of an organisation a communication channel from the execution environment of the application back to the environment of the submitter most often is not available.
The elasticLM solution enables the application to evaluate the authorisation for the execution locally, without any network connection to the license management system of the submitter. All necessary information for a policy decision is in the token, which is sent to the execution environment prior to launching the application.
Additional mechanisms ensure that re-using the token multiple times for different application executions is not possible.
