Containers

Bare Metal

Focus developers on LOB needs, not infrastructure



What Is a Function?

Auto-scaled Lower Cost

Event Driven Stateless Short Duration

Recent open source from Google

Built on top of Kubernetes and Istio

Components to be used as building blocks



Serving – main component integrated tightly with Istio and provides ingress, routing and scaling

Building – a pluggable service that builds images based on the templates

Eventing – responsible for event bus and channels (subscriptions). Event bus is pluggable to support different transports. [currently unreleased]

Knative components
