PostNL's Greengrass Journey - How PostNL modernized 1100 Parcel Lockers using Greengrass.
Join us as we explore PostNL's transformative journey in modernizing 1100 parcel lockers across The Netherlands using AWS IoT Greengrass. In this talk, we detail how an aging Java-based system was replaced by a cutting-edge, Fedora IoT–powered architecture, featuring a robust Node.js core, a sleek VueJS interface, and a modern cloud stack with AWS AppSync and GraphQL.
We'll dive into real-world challenges—from navigating MQTT identity conflicts to overcoming DNS misconfigurations—and reveal how strategic, phased migrations ensured seamless operations despite high-stakes delivery demands. Attendees will discover how leveraging Greengrass components not only streamlined remote deployments but also provided a resilient backup communication channel, turning technical hurdles into innovative solutions in the fast-paced world of parcel delivery.
