[Tweet](https://twitter.com/share) ### Listen to a recent episode of Inductive Automation's *Ignited* podcast to see how the open-source MQTT protocol has completely changed industrial data architectures. Are you looking to build systems that move data—reliably and securely—across an enterprise? Have proprietary approaches slowed you down or locked you in? Episode 4 of Inductive Automation's new *Ignited* podcast is a must listen! The co-inventor of MQTT, Arlen Nipper, and Opto 22 VP Benson Hougland are the featured guests on this podcast, reviewing industrial automation technology and taking you into the future. Inductive Automation's Travis Cox and Thomas Burke host this discussion about why MQTT and Sparkplug B are now the key to scalable industrial data, and why edge computing changes everything. Listen in on these insightful conversations: This episode also covers several other topics, like:  - Unified Namespace (UNS) - Cybersecurity - MQTT vs. OPC UA (or do they really work best together?) You'll also get a peek at some live online demos and hear about some real-world application stories from the Opto 22 case study library. Interested in the applications discussed during the podcast? You can find the complete case studies below. - [ Genesee County](https://www.opto22.com/products/case-studies/case-study-ending-communication-failures-across-18) - Water/Wastewater application using MQTT, Sparkplug B, *groov* EPIC, Ignition & Ignition Edge  -  [Moriroku Technology North America](https://www.opto22.com/products/case-studies/case-study-automotive-manufacturer-accelerates-dig) - Tier 1 Automotive application using MQTT, Sparkplug B, *groov* RIOs, and   Ignition  -  [Nautilus Data Technologies](https://www.opto22.com/products/case-studies/case-study-liquid-cooling-for-data-centers-and-sta) - Data Center Operator and Cooling Distribution Unit (CDU) OEM application using MQTT, Sparkplug B, *groov* EPIC, and Ignition Edge  [![CASE STUDY LIBRARY](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/439485/42a1d726-c6f7-4681-b03d-1d78801585b6.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/439485/42a1d726-c6f7-4681-b03d-1d78801585b6) *Thanks for listening!* Topics: [MQTT](https://blog.opto22.com/optoblog/topic/mqtt), [Ignition Edge](https://blog.opto22.com/optoblog/topic/ignition-edge), [Sparkplug](https://blog.opto22.com/optoblog/topic/sparkplug), [Ignition](https://blog.opto22.com/optoblog/topic/ignition), [podcast](https://blog.opto22.com/optoblog/topic/podcast), [OPC UA](https://blog.opto22.com/optoblog/topic/opc-ua) ### Written by [Janice Colmer](https://blog.opto22.com/optoblog/author/janice-colmer) Janice has worked at Opto 22 for over 20 years and is part of the marketing team that strives to share new and relevant content with the industrial automation industry.
