Cloud Native Development Architectural Diagrams Demos

  • Cloud-native development is an approach to building and running applications to fully exploit the advantages of the cloud computing model (i.e. responsive, elastic and resilient applications).
  • Portfolio Architecture Workshops for creating impactful architectural diagrams. This workshop will teach you how to use, design, and create architectural diagrams based on the tooling and Red Hat Portfolio Architecture design elelements. You’ll leverage existing portfolio architecture diagrams as starting points.

Red Hat AMQ Streams (Kafka)

  • HTTP-based Kafka messaging with Red Hat AMQ Streams
  • Message broker integration made simple with Red Hat Fuse This article presents a sample integration between Red Hat AMQ 7 and IBM MQ, using Red Hat Fuse 7 for the integration. Traditionally, developers have used resource adapters for message bridging with external systems. A resource adapter is a system library that provides connectivity to an enterprise information system (EIS). Similar to how a Java Database Connectivity (JDBC) driver provides connectivity to a database management system, a resource adapter plugs into an application server such as Red Hat JBoss Enterprise Application Platform (JBoss EAP). It then connects the application server, enterprise information system, and the enterprise application.

Jenkins and GitHub


  • SdkMan is a tool for managing parallel versions of multiple Software Development Kits on most Unix based systems. It provides a convenient Command Line Interface (CLI) and API for installing, switching, removing and listing Candidates. Formerly known as GVM the Groovy enVironment Manager, it was inspired by the very useful RVM and rbenv tools, used at large by the Ruby community.
  • Using Jenkins Pipeline parallel stages to build Maven project with different JDKs
  • Demo: A single Jenkinsfile, a Java Maven project, a single Dockerfile, multiple Java versions build and tested in parallel thanks to SDKMAN:

Jenkins Scripts

  • cleanup.Jenkinsfile: Jenkinsfile with Declarative Pipeline Multiline sh that cleanups old builds. All the Stages are now visually monitored. It is triggered every saturday night and ends with jenkins restart. These Multi-line bash commands make easier to read Jenkins Projects.
  • daily_restart.Jenkinsfile: A script that automatically triggers a daily restart of Jenkins due to performance issues (Jenkins is a Java application). Jenkins with Declarative Pipeline multiline sh that restarts Jenkins every night except on Saturday nights (when cleanup.Jenkinsfile is triggered).
  • confluence6-docker-build.Jenkinsfile: Declarative Jenkinsfile for building and uploading a docker image to Openshift-DEV, Dockerhub and Openshift-PROD (Stages are disabled via Conditional Build Steps). Tip: A Docker Plugin for Jenkins can easily replace this Jenkinsfile.
