The story of transitioning a large financial company to practice Continuous Delivery on top of Openshift using only open source solutions. Cloud Native is new and rapidly evolving, which makes enterprise clients anxious -- so they jump to large, monolithic vendor solutions in search of an automatic “right answer.” These solutions can be over complicated and rigid, ultimately stifling innovation. This financial institution needed a system flexible enough to support about fifty development teams independently deploying microservices while enforcing strict security and compliance requirements. Using open source tools we were able to give our client exactly the security and flexibility they needed, without locking them into a one size fits all solution. Our solution is built using the Gitops pattern, Jenkins, Docker and Openshift/Kubernetes - all open tools which can be used at any other company. I will explain the design decisions, the technical solution and the challenges of onboarding development teams to the new platform.
