The document discusses DevOps approaches for enabling dynamic interoperability between IoT, edge, and cloud systems. It notes the diversity and complexity of developing IoT cloud applications using various cloud, edge, and IoT resources. It identifies interoperability issues that can occur within and across these systems. It provides an example of interoperability challenges in a maritime port system. And it proposes the use of artifacts, like middleware services and data pipelines, that can be deployed automatically across environments to help achieve dynamic interoperability.
