While it may be convenient to follow simple steps to get connectivity working for your IIoT solution, sometimes you are better off having an understanding of the elements that make up the broad spectrum of connectivity technologies.To understand the foundations upon which IoT protocols are built, I had a conversation with Dominik Obermaier. Dominik is the Co-Founder & CTO of HiveMQ, a company that provides an MQTT broker and a client-based messaging platform to over 130 customers including many Fortune 500 companies for mission-critical use cases like connected cars, logistics, Industry 4.0, and connected #IoT products.Dominik is also a member of the OASIS Technical Committee responsible for developing the MQTT specification, and he's also involved in the standardisation of Sparkplug.Here's the outline of the discussion linked below:✔️ IoT Connectivity Architectures✔️ Data Encoding Mechanisms✔️ COAP Protocol✔️ AMQP Protocol✔️ XMPP protocol✔️ Fundamentals of MQTT Protocol✔️ Plug and Play Interoperability Using Sparkplug B✔️ Adoption of Sparkplug B in Manufacturing✔️ #MQTT Broker Deployment Options✔️ Kubernetes for High Availability MQTT Broker Deployments✔️ Backend IoT Architecture for MQTT✔️ #IIoT Security✔️ MQTT Use Case in Smart Manufacturing✔️ HiveMQ
