Presented at Open Source Summit Japan with Jonathan Schweikhart on June 21, 2018. Abstract: The 40 Node.js microservices making up the IBM Cloud UI historically have been deployed as apps on Cloud Foundry (CF), an open source PaaS. But, recently, this enterprise microservice system has been migrated to run on Kubernetes to take advantage of improved orchestration, higher availability, and better performance. Tony Erwin & Jonathan Schweikhart will discuss their team's journey and provide you with insights into the advantages of Kube over CF. Even more importantly, they will describe approaches to solving new problems that took the place of old ones, such as: 1) adapting PaaS apps to run as containers on Kube, 2) enabling geo load balancing between the different runtimes (to vette Kube before completely turning off CF), 3) integrating tools like Prometheus into existing monitoring systems, and more! Their team's first-hand experiences will help you avoid pitfalls as you prepare your own migrations to Kube!

If you have access to CF API 2.115.0 or higher (released on June 25, 2018), you can leverage CF's service discovery feature (see https://docs.cloudfoundry.org/devguide/deploy-apps/cf-networking.html#discovery ).
