How agents broke app-level infrastructure - Evan Boyle
Jun 3, 2025 · 13:32
Evan Boyle, founder of GenSX, argues that LLM-powered agents have broken assumptions about app-level infrastructure, as p1 latency jumps from milliseconds to seconds and workflows run minutes to hours. He explains that traditional serverless providers timeout after 5 minutes, lack native streaming, and force brittle Rube Goldberg machines on top of queues like SQS or tools like Airflow. Boyle presents an open-source library that separates API and compute layers using Redis streams for resumability, enabling users to refresh pages or navigate away without losing progress. He demonstrates components with built-in retries, caching, and tracing, and a workflow that automates Hacker News analysis. Key architectural lessons include starting simple but planning for long-running agents, keeping compute and API planes separate, and leaning on Redis for resumability.
