The world of edge AI is rapidly transforming how devices and data centers work together. Imagine healthcare tools powered by AI, or self-driving vehicles making real-time decisions. These advancements rely on bringing AI directly to edge devices. However, building a robust architecture for diverse edge environments presents significant hurdles.
This blog introduces our new reference architecture, designed to simplify edge AI deployment. It outlines a clear solution, highlights key design considerations, and explains the selection of each component, with a strong focus on our collaboration with NVIDIA.
Managing edge solutions presents unique challenges. Picture vast networks of devices, scattered across diverse locations. This scale demands exceptional scalability. As the number of devices grows, deployment, updates, and monitoring must remain streamlined.
Moreover, edge software often needs to operate independently. Many deployments face limited or no remote connectivity. Therefore, devices must be capable of self-recovery when issues arise.
Security is another crucial factor. Edge devices are susceptible to both physical and software attacks. Strong protective measures and consistent security updates are essential.
Finally, resource limitations pose a significant hurdle. Edge devices typically have constrained RAM, necessitating efficient resource utilization.
Edge devices, equipped with NVIDIA GPUs, require a lightweight and secure operating system and appropriate GPU drivers. The model is then deployed across multiple devices, with continuous retraining and updates. Effective model deployment and maintenance in offline environments are essential due to diverse deployment locations.
This architecture emphasizes the use of open source solutions alongside NVIDIA accelerated computing for optimal performance and flexibility. The solution provides guidance for both the training and inference environments, including hardware and software components, tool versions, and integration considerations.
The inference environment is where the magic happens, where edge devices actively process data. It’s designed for flexibility, running on diverse hardware as long as minimum requirements are met. To boost performance, optimization engines like NVIDIA TensorRT are employed, especially for models built with popular frameworks. Quantization further refines models, reducing their size and power needs. Lightweight, secure operating systems like Ubuntu Core provide the foundation, with features like TPM-based encryption and seamless NVIDIA driver integration.
Meanwhile, the training environment is where models are conceived and honed. Secure software distribution through Snaps, powered by Ubuntu Core’s robust security, is key. Data from edge devices is efficiently managed by Apache Kafka, feeding into the retraining process. MLOps platforms like Kubeflow and MLflow automate these pipelines, while tools like Juju and Charms simplify the orchestration of complex components.
Organizations can successfully implement AI at the edge by carefully considering hardware and software compatibility and their ability to deploy and maintain ML models. Open source solutions like Charmed Kubeflow and KServe are well-suited for these scenarios, allowing organizations to use a consistent software vendor across data centers and edge environments. Canonical provides a comprehensive stack for easy and secure edge AI deployment and management.
