Episode 24 — Place OT Workloads in Cloud and Edge: Public, Private, Hybrid, and Vendor Services

This episode teaches how OT workloads are increasingly split across on-prem, edge, and cloud locations, and how to reason about security and resilience when data and control functions move outside the traditional control network. You’ll define public, private, and hybrid cloud models in a way that ties directly to OT realities, including latency sensitivity, outage tolerance, regulatory constraints, and vendor support requirements. We cover edge computing as a way to keep time-critical processing close to the process while still enabling centralized analytics, patch management, or fleet operations, and we explain the risk of hidden dependencies such as DNS, certificates, identity providers, or WAN links. You’ll learn best practices for secure placement decisions, including strict separation of monitoring from control, clear trust boundaries, hardened gateways, and explicit recovery plans for when cloud services degrade. Troubleshooting considerations focus on diagnosing failures that look like “OT problems” but are actually identity, routing, certificate, or service-side issues, and selecting corrective actions that protect uptime and evidence.
