We'd like to announce the latest release of OpenShift Serverless, version 1.14! This release targets, and is available for free, as part of OpenShift Container Platform 4.7 and 4.6.  

Since our initial release, the adoption of serverless continues to grow and we see an uptick across several industries, especially around Financial Institutions, Telecommunications and Technology companies. 

With Serverless the infrastructure is abstracted away from the app development process, meaning developers can focus on coding business logic and value into the business applications. Serverless also provides the auto-scaling of applications, meaning that business applications can easily scale up, down, and also to zero, meaning that these applications can dynamically meet the demand placed on them  

The ability to scale these applications to zero when not in use has the added benefit of freeing up valuable compute resources on the underlying infrastructure.

Serverless 1.14 is based on the open-source project Knative version 0.20 and apart from adding Knative Kafka plugin to GA, brings several new features and experiences to OpenShift.

You can now build and deploy serverless computing on IBM Z and IBM LinuxONE with Red Hat OpenShift Serverless. This new offering is available as a no-charge add-on to the Red Hat OpenShift Container Platform.  

As you architect new solutions, Eventing provides the capability to build event-driven applications that can connect to and from several systems running on-premises, on the cloud, and inside or outside of Kubernetes. With Knative Kafka plugin being GA with OpenShift Serverless 1.14 you can leverage the Eventing component to build true Event Driven serverless applications ready for production.  

We recorded a short introduction to Eventing, you can watch it here. It enables powerful constructs such as:

  • Event Sources, which connect to external systems and convert those from their native formats to Cloud Events, enabling greater portability and consistency across different infrastructure regardless of wherever those events originated from.
  • Brokers, which can be used to connect multiple event sources and then route those events based on attributes, such as the event type, with a multi-tenant, more operationally-efficient model. 
  • Channels, which are useful when you have the same event type and want the same events to be processed by more than one application, and can help organizations move to event-driven microservices with easier management at scale. 

This release includes Kafka Channel/Event Source as well as several event sources, powered by Camel-K (TP), such as AWS Kinesis, AWS SQS, Salesforce, Telegram, Slack, JIRA, alongside our built-in Event Sources (Kubernetes APIs,  Ping, Kafka, and ContainerSource).

With the addition of Serverless functions (currently in Developer Preview), we are striving to complete the Serverless offering with all the necessary constructs developers need to build modern cloud-native applications.  OpenShift Serverless functions OOTB runtimes include Quarkus, Node.js, Spring BootNew and Go, are based on the CNCF Buildpacks project. These functions can be invoked by plain HTTP Requests as well as Cloud Events to leverage the Eventing component. We call this Serverless with flexibility

Deploying your first serverless container is super-easy!

Integrations with OpenShift Service Mesh, OpenShift Pipelines, and many other platform features have also improved.  You can, for example, "import a project from Git" and automatically have  a Tekton pipeline created, simplifying your journey into Continuous Integration (CI) and automation.  

Here is a recording for a more elaborated demo using OpenShift Pipelines, including Triggers, and Revisions.

These are just some of the highlights, you will find other features and more details as part of the release notes.
