¿Does anyone know if flowable run and perfrom well over OpenShift?
Considering that OpenShift is a container application platform based on Kubernetes, there shouldn’t be any particular issue with it. We have been running Flowable on Docker Swarm and Kubernetes for a long time. You should only take into account regular issues with Java in a Docker environment, like memory settings if you are using older Java versions (https://blog.softwaremill.com/docker-support-in-new-java-8-finally-fd595df0ca54).
Also there’s a repo with a benchmark that you could run yourself https://github.com/flowable/flowable-benchmark
