The original promise—pay‑only‑for‑what‑you‑use—remains compelling, but early serverless platforms were largely stateless: a function receives an event, runs, returns a result, and the runtime disappears. ...

Introduction Large Language Models (LLMs) such as GPT‑4, LLaMA, and PaLM have transformed natural language processing, enabling capabilities ranging from code generation to conversational agents. However, the sheer size of these models—often exceeding tens or even hundreds of billions of parameters—poses a formidable challenge when it comes to inference latency. Users expect near‑real‑time responses, especially in interactive applications like chatbots, code assistants, and recommendation engines. Achieving low latency while maintaining high throughput requires a deep integration of software optimizations and high‑performance computing (HPC) architectures. ...

Yet, the same cloud‑centric mindset that powers ChatGPT or Claude also creates latency, privacy, and cost concerns for many real‑world use cases. Running LLM inference locally—whether on a laptop, edge device, or an on‑premise server—offers immediate responsiveness, data sovereignty, and the possibility of fine‑grained control over model behavior. ...

Introduction Distributed machine‑learning (ML) workloads—such as large‑scale model training, hyper‑parameter search, and federated learning—rely heavily on fast, reliable communication between compute nodes, parameter servers, and auxiliary services (monitoring, logging, model serving). In these environments a message broker acts as the nervous system, routing control signals, gradient updates, model parameters, and status notifications. When latency spikes, the entire training loop can stall, GPUs sit idle, and cost efficiency drops dramatically. This article explores how to design low‑latency message brokers specifically for real‑time communication in distributed ML clusters. We will: ...
