<p>OpenShift&#160;Cloud&#160;Functions provides the missing integration link between OpenShift deployments and components which enable serverless functionality, like Knative and Istio (Service Mesh).
Serverless concepts like scaling pods and containers on demand, or managing apps using Operators via the Operator Lifecycle Manager (OLM), are now possible on OpenShift using OpenShift&#160;Cloud&#160;Functions.</p>
