Description

Creates a unique session which can be used to associate subsequent Amazon EC2 (Elastic Compute Cloud) steps. This provides a single task the ability to execute numerous EC2 operations associated to a specific session.

NOTE: To end a session, use the End Session activity.

 

IMPORTANT: The EC2 activities are performed using Amazon's EC2 engine. You must enter a valid Amazon EC2 service account in order for these activities to work properly.

Practical Usage

Ideally used to create a session to correlate subsequent Amazon EC2 activities to. Creating a session eliminates having to re-enter specific requirements for each activity.
