Kubernetes has quietly become the de facto control plane for production AI inference. This post walks through the architecture, the GPU plumbing, and the patterns teams use to serve models that actually meet SLOs.
Introduction Autonomous agents—whether they are self‑driving cars, swarms of delivery drones, or collaborative factory robots—rely on real‑time machine‑learning inference to perceive the world, make decisions, and execute actions. As the number of agents grows and the complexity of models increases, a single on‑board processor quickly becomes a bottleneck. The solution is to distribute inference across a fleet of heterogeneous compute nodes (cloud GPUs, edge TPUs, FPGA accelerators, even spare CPUs on nearby devices) and to dynamically allocate those resources based on workload, latency constraints, and power budgets. ...
Introduction In 2026 the edge is no longer a peripheral afterthought in the artificial‑intelligence ecosystem—it is the primary execution venue for a growing class of Small Language Models (SLMs). These models, typically ranging from 10 M to 500 M parameters, are deliberately engineered to run on resource‑constrained devices such as micro‑controllers, smart cameras, industrial IoT gateways, and even consumer‑grade smartphones. The shift toward on‑device inference is driven by three converging forces: ...
Introduction Enterprises are increasingly deploying real‑time AI inference services that must respond to thousands—or even millions—of requests per second while delivering low latency (often < 50 ms). Typical workloads involve: Embedding generation (e.g., sentence transformers, CLIP) Similarity search over billions of high‑dimensional vectors Retrieval‑augmented generation (RAG) pipelines that combine a language model with a vector store Streaming inference for video, audio, or sensor data Achieving this level of performance requires elastic compute, high‑throughput networking, and state‑of‑the‑art storage for vectors. Kubernetes offers a battle‑tested orchestration layer for scaling containers, while distributed vector databases (Milvus, Qdrant, Weaviate, Vespa, etc.) provide the low‑latency, high‑throughput similarity search that traditional relational stores cannot. ...

From autonomous drones to retail kiosks, the demand for instantaneous, locally‑processed intelligence is reshaping how we design AI‑enabled services. Yet, the edge is constrained by limited compute, storage, and network bandwidth. The classic cloud‑centric model—send data to a remote GPU, wait for inference, receive the result—simply cannot meet the sub‑10 ms latency requirements of many real‑time applications. ...
