Knative
Kubernetes-based platform to build, deploy,
and manage modern serverless workloads
Three core components:
• Build - Source-to-container build orchestration
• Serving - Request-driven compute that can scale to zero
• Eventing - Management and delivery of events
100% open source. Created by Google with contributions from Pivotal and others

riff is for functions
• event driven Function as a Service
• opinionated experience built atop Knative, Kubernetes and Istio
• functions practice Inversion of Control
• no servers, ports or messaging protocols, just your logic
• pick your language runtime:
• Java/Spring
• JavaScript/Node
• executable commands
• more from the community
