OpenShift Serverless simplifies the process of delivering code from development into production by reducing the need for infrastructure set up or back-end development by developers.
Developers on OpenShift Serverless can use the provided Kubernetes native APIs, as well as familiar languages and frameworks, to deploy applications and container workloads.
OpenShift Serverless on OpenShift Container Platform enables stateless serverless workloads to all run on a single multi-cloud container platform with automated operations. Developers can use a single platform for hosting their microservices, legacy, and serverless applications.
OpenShift Serverless is based on the open source Knative project, which provides portability and consistency across hybrid and multi-cloud environments by enabling an enterprise-grade serverless platform.
The set of supported features, configurations, and integrations for OpenShift Serverless (current and past versions) are available at the Supported Configurations page.
This section describes the components of OpenShift Serverless.
Knative Serving on OpenShift Container Platform builds on Kubernetes and Kourier to support deploying and managing serverless applications.
It creates a set of Kubernetes custom resource definitions (CRDs) that are used to define and control the behavior of serverless workloads on an OpenShift Container Platform cluster.
These CRDs are building blocks to address complex use cases, for example:
Rapidly deploying serverless containers.
Automatically scaling pods.
Viewing point-in-time snapshots of deployed code and configurations.
Knative Eventing on OpenShift Container Platform enables developers to more easily declare how components of their system communicate, using an event-driven architecture for serverless applications. Event-driven architecture is based on the concept of decoupled relationships between event producers and event consumers.
