Basically there are a few new Linux kernel features (“namespaces” and “cgroups”) that let you isolate processes from each other and set controls on their resource usage. When you use these features, you call it a “container” Julia Evans

Knative Described by Google as a “collection of components that [extend Kubernetes and] provide the missing building blocks that developers need to create modern, source-centric, container-based cloud-native applications.” Basically, it’s a simpler way for developers to deploy and run serverless apps and functions atop Kubernetes and Istio.
