The heterogeneous and dynamic nature of the Internet of Things (IoT) creates challenges that go beyond the traditional computer-based network model. These challenges are commonly related to the fragmented and unpredictable mixture of devices with individual capabilities that may pose a barrier to achieving interoperability and managing devices in the context of IoT. This study addresses interoperability and management challenges by introducing a tool for achieving interactive job execution over a network of heterogeneous devices. The proposed tool, named Runlet, is a cross-platform application that runs across many architectures and operating systems, such as ARM, Linux, macOS, and Windows. It uses both the protocol Advanced Message Queuing Protocol (AMQP) and the broker RabbitMQ for reliable message delivery. The protocol AMQP is an open standard Machine-to-Machine (M2M) publish/subscribe messaging protocol optimized for high-latency and unreliable networks that enables client applications to communicate with conforming messaging middleware brokers. RabbitMQ is an open-source lightweight message broker that supports various messaging protocols and can be deployed on-premises and in the cloud. The architecture of Runlet is discussed in detail both conceptually and computationally, including the reasoning behind architectural decisions and selected technologies. The evaluation is conducted through an experimental approach that assesses interactivity and reliability on a testbed of devices composed of single-board ARM computers and laptop devices. The experimental results show that the application offers interactivity under different scenarios and provides reliable message delivery even after server failover.
