Nuclio is a real-time, open source serverless platform, used to minimize development and maintenance overhead and automate the deployment of data-science based applications. The Nuclio processor is real-time: a single Nuclio function processor runs 370,000 function invocations per second (with a simple Go function) and responds in 0.1ms latency, which is 100x faster than most serverless/FaaS solutions. Nuclio has an open architecture which supports many event and data sources and enables fast deployment. It can be consumed either as a self-hosted framework or as a managed service in Iguazio.
