Why the Next Wave of AI Apps Won't Run in Centralized Cloud
Blog post from Azion
Distributed AI inference processes request handling, caching, retrieval, and sometimes model execution near users rather than routing all traffic through a centralized cloud region, aiming to reduce the network latency, cold starts, and origin congestion that can compound across multi-step AI workflows. The material argues that Azion supports this approach through globally distributed AI Inference, cold-start-free Functions based on V8 isolates, semantic caching, vector search for retrieval-augmented generation, LoRA fine-tuning, edge security tools, and real-time observability. It reports that distributed preprocessing and caching can reduce global p50 latency by up to 75%, lower origin load by up to 60%, and achieve semantic-cache hit rates of 20–40% in workloads such as support, search, and content generation, while centralized requests may add 100–180 milliseconds before inference begins. A fraud-detection checkout example illustrates how security filtering, caching, request processing, fine-tuned model execution, and event logging can operate across the platform, with the approach positioned as most relevant to real-time AI features, RAG applications, and agentic workflows rather than offline training or batch processing.
