OpenFaaS Product Background, Business Scenario, Architecture Design and Implementation
To replace wasteful physical‑machine scripts on Baidu’s Aladdin search platform, the team adopted OpenFaaS on a Kubernetes cluster, using its event‑connector, Prometheus‑driven autoscaling, and high‑availability gateway to run synchronous, scheduled, and asynchronous functions, achieving stable deployments with only 14 % CPU and 8 % memory of the original.
