The document discusses implementing scalable Salesforce integrations using an event-driven architecture with platform events. It begins by outlining challenges with traditional point-to-point integrations such as lack of scalability and tight coupling. The presentation then introduces platform events as a solution, explaining how they allow for asynchronous, decoupled communication using a publish-subscribe model. The remainder of the document provides a demo of building an order management integration using platform events, including creating event schemas, publishing and subscribing to events from Apex and Process Builder. Additional resources on platform events are also listed.
