OpenShift Serverless now GA

Today, we are pleased to announce the general availability of OpenShift Serverless. Based on the Knative open source Kubernetes serverless project, OpenShift Serverless enables developers to build what they want, when they want, with whatever tools and languages they need. Developers can quickly get their applications up and deployed using serverless compute, and they won't have to build and maintain larger container images to do so.

OpenShift Serverless enables choice for developers. They're able to use the frameworks and languages they need without forcing the IT team to support extra technologies. Developers can build with Ruby-on-Rails, Spring, and Django, among other language-specific frameworks. Those applications can then be tied into event streams and triggered by things that take place in your environment, rather than running full time and burning CPU cycles.

OpenShift Serverless also includes the following capabilities.

• Extensive choice of programming languages and runtimes for serverless applications, letting developers use preferred tools.
• Auto-scaling up and down based on requests and events, which helps shift resource consumption based on current rather than legacy needs.
• Full integration with OpenShift Pipelines, a Kubernetes-style continuous integration (CI) and continuous delivery (CD) solution that uses Tekton building blocks.
• A Red Hat Operator-based foundation, which lets administrators more safely manage and update running instances at scale, and provides a cloud-service-like experience for an application’s lifecycle.
• Continued tracking of community release cadence, including Knative 0.13 Serving, Eventing, and kn—the official Knative CLI. As with anything we ship as a product at Red Hat, this means we have validated these components on a variety of different platforms and configurations OpenShift runs.

OpenShift 4.4 makes it easier than ever to deploy applications using OpenShift Serverless by providing you a simplified way to deploy Knative Services within the Developer perspective of the OpenShift Web Console.

Now, you can select a Knative Service Resource Type when adding a new application into the project, instantly allowing any application to benefit from the power that is OpenShift Serverless—including the ability to scale to zero when idle, as shown in Figure 2.
