The release of Streams v5.2 includes a change in the overall architecture of the platform. Streams v5.2 is a cloud-native application runtime environment. This means that not only is it still available as an add-on service in IBM Cloud Pak for Data, it can also be installed on Red Hat OpenShift or Kubernetes environments. When Streams is installed outside of the Cloud Pak for Data environment in Kubernetes or OpenShift, this is called a stand-alone deployment.
This video by Paul Gerver discusses the new Streams architecture.
