Developing an IoT system as a service requires careful planning and considerations in terms of communication technology usage and management of IoT end node devices. These IoT nodes are generally resource constrained to run Kubernetes on their own. Additionally, there is a diverse range of wireless technologies used in the IoT field, making it more complex to achieve interoperability. While Project-Flotta focuses on edge devices and workload management, this talk explores the extended approach to Project-Flotta for dynamic management and observability of IoT end nodes in a heterogeneous wireless setup. We delve into the reasons behind this approach and the significant role it plays in achieving interoperability and ensuring seamless integration between different IoT wireless technologies.
