Part 1 is a screencast overview of your integration options (ADN login is required to view it). If you are getting started with Salesforce integration or maintaining a curriculum for people in your company, this is a good place to point them to. Part 1 should help you visualize the various options and segment them in your mind, so you can figure out the integration method that works best to address your needs.
Part 2 is called “Next Generation Integration Services”, which will talk about new capabilities in store for the platform. No date is published for it. Just that it’s “coming soon”.
