The rise of edge devices, IoT sensors, and decentralized networks has opened a new frontier: performing inference where the data lives. Yet, moving heavy neural networks to untrusted or resource‑constrained environments introduces two major challenges: ...

Introduction Retrieval‑Augmented Generation (RAG) has rapidly emerged as a cornerstone for building intelligent applications that combine the expressive power of large language models (LLMs) with up‑to‑date, domain‑specific knowledge. While the classic RAG pipeline—retrieve → augment → generate—works well in centralized data‑center settings, modern use‑cases demand real‑time responses, low latency, and privacy‑preserving execution at the network edge. Enter vectorized stream processing: a paradigm that treats high‑dimensional embedding vectors as first‑class citizens in a continuous dataflow. By vectorizing the retrieval and similarity‑search steps and coupling them with a streaming architecture (e.g., Apache Flink, Kafka Streams, or Pulsar Functions), we can: ...

Introduction The rapid democratization of large language models (LLMs) has opened doors for developers to embed sophisticated natural‑language capabilities into a wide range of products. However, the sheer size of state‑of‑the‑art models—often exceeding tens of billions of parameters—poses a serious obstacle for local edge deployment. Edge devices such as Raspberry Pi, NVIDIA Jetson modules, or even micro‑controllers have limited memory (often < 8 GB), constrained compute (CPU‑only or low‑power GPUs), and strict latency budgets. ...

Introduction Serverless platforms have democratized backend development. With a few lines of JavaScript or Python, developers can deploy functions that automatically scale, handle routing, and pay‑only-for‑what‑they‑use. However, as applications mature, the limits of traditional serverless become evident: cold‑start latency, opaque runtime environments, limited language choices, and constrained performance for compute‑intensive workloads. Enter Rust and WebAssembly (Wasm). Rust offers memory safety without a garbage collector, deterministic performance, and a vibrant ecosystem for networking and cryptography. WebAssembly provides a portable binary format that runs in lightweight sandboxes across browsers, edge runtimes, and even standalone VMs. When combined, they enable high‑performance microservices that run at the network edge, delivering millisecond‑level response times while preserving the operational simplicity of serverless. ...

Introduction Edge intelligence—bringing AI inference and training capabilities to devices at the network edge—has moved from a research curiosity to a production necessity. From autonomous drones and industrial IoT sensors to smart cameras and wearables, the demand for real‑time, privacy‑preserving machine learning is exploding. Federated Learning (FL) offers a compelling answer: models are trained collaboratively across many devices without ever moving raw data to a central server. However, the naïve FL loop (select clients → download model → train locally → upload updates) was designed for offline scenarios where latency, bandwidth, and privacy budgets are relaxed. In a real‑time edge environment, we must simultaneously address: ...
