Abstract—Exploring how DevOps principles can enhance the deployment of distributed Internet of Things (IoT) systems offers a novel perspective, transcending traditional software delivery methodologies. This paper examines some of the primary challenges involved, such as the extensive diversity of physical devices, the unique security concerns related to physically dispersed devices, and the complexities of automated testing for systems integrating hardware and software. We identify three principal challenges: the suitability of CI/CD pipelines across various constrained and diverse hardware platforms, methods to automate end-to-end security (DevSecOps) on exposed surfaces susceptible to attacks, and the development of automated testing frameworks for hybrid systems. To address these challenges, we propose a comprehensive framework that incorporates Hardware Abstraction Layers (HALs) to manage device diversity, employs lightweight cryptography for security, and utilizes multi-tiered testing strategies through Hardware-in-the-Loop (HIL) simulation. Our case studies support the premise that overcoming these challenges can facilitate faster, more secure, and resilient IoT deployments.
