Nuclio is a new serverless project, derived from iguazio’s elastic data life-cycle management service for high-performance events and data processing. You can use nuclio as a standalone binary (for example, for IoT devices), package it within a Docker container or integrate it with a container orchestrator like Kubernetes.
nuclio is extremely fast. A single function instance can process hundreds of thousands of HTTP requests or data records per second. This is 10 – 100 times faster than some other frameworks. See nuclio Architecture to learn how it works and watch a technical presentation to the CNCF with demo (slides can be found here).
