At the present moment, it is quite clear that the future of industrial automation will be driven by software. More so, that of IIoT. And, due to the merits that have allowed it to dominate in the IT space, Open Source software is likely to lead the industrial software revolution. Regardless of the conservative nature of the industry. To discuss the use of Open Source in building IIoT solutions, I had a conversation with Frédéric Desbiens. Frédéric is the Program Manager for IoT and Edge Computing at the Eclipse Foundation, managing close to 50 Open Source projects under Eclipse IoT. Here's the outline of the discussion. ✔️ Key Challenges for Implementing IIoT ✔️ Why Open Source Matters for IIoT Implementation ✔️ Key Components of an Industrial IoT Solution ✔️ Open Source Stack for IIoT Gateways ✔️ Open Standards for IIoT Data Aggregation ✔️ Why Semantic Interoperability Matters for IIoT ✔️ Real Value of MQTT Sparkplug to Implementers ✔️ Real Value of MQTT Sparkplug to End-Users ✔️ Is MQTT Sparkplug a Lock-In? ✔️ Open Source Digital Twin Frameworks and how they work ✔️ Open Source Software for IIoT Security ✔️ Role of Eclipse Foundation and Eclipse IoT
