A Polymorphic Unikernel Service (PUS) system generates and customizes unikernels using a generic unikernel, leveraging kvirt support, to create specialized unikernels compatible with target IoT devices, embedding them within virtual machines for deployment, optimizing for hardware and network capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a generic unikernel is deployed to diverse IoT devices, then deployment speed is improved, but compatibility with hardware constraints deteriorates
Solution Approach 1:
The system dynamically generates customized unikernels based on the specific hardware capabilities and constraints of each IoT device. Instead of using a static generic unikernel, the system adapts the unikernel configuration in real-time to match device requirements, resolving the contradiction between deployment speed and hardware compatibility.
Solution Approach 2:
The system changes parameters of the unikernel (such as enabled features, library selections, and configuration options) based on the target device's hardware capabilities. This parameter adaptation allows the same base unikernel template to be customized for different device types while maintaining efficient deployment through automated generation.
2Adaptability or versatility
If device-specific customization is performed for each IoT device, then hardware compatibility is improved, but system complexity increases
Solution Approach 1:
The system employs a universal device capability description format and a standardized unikernel generation process that works across all IoT device types. This universal approach allows the system to handle device-specific customization through a consistent methodology, reducing overall system complexity while maintaining hardware compatibility.
Solution Approach 2:
The system automatically generates customized unikernels based on device capability information without requiring manual configuration for each device. This self-service approach eliminates the need for complex manual customization processes, reducing system complexity while achieving device-specific optimization.
3Ease of manufacture
If minimal unikernel configuration is used, then deployment cost is reduced, but security vulnerability increases
Solution Approach 1:
The system applies local quality by enabling specific security features and libraries only where needed based on the device's role and requirements. Instead of using a uniform minimal or full configuration across all devices, each unikernel is customized with the appropriate security features for its specific function, optimizing both cost and security.
Solution Approach 2:
The system performs preliminary security hardening during the unikernel generation process by automatically configuring security features, libraries, and settings before deployment. This preliminary action ensures that security is built-in from the start rather than added later, maintaining both low deployment cost and high security resilience.

AI summary
The present disclosure provides new and innovative systems and methods for managing nodes using polymorphic unikernals. In an example, a method includes generating, by a polymorphic unikernal service (PUS) system having a processor, a virtual machine. A generic unikernal may be created, retrieved, and/or embedded within the virtual machine. The PUS system may receive, from an Internet of Things (IoT) device (e.g., one of a plurality of nodes communicatively linked to the PUS system), a configuration file indicating a configuration of the IoT device. The PUS system may modify the generic unikernal to generate a modified unikernal based on the configuration of the IoT device. Furthermore, the PUS system may deploy the virtual machine on the IoT device. The deployed virtual machine may be embedded with the modified unikernal.
