Checkout flogo.io - specifically Flogo Flow action https://github.com/project-flogo/flow for orchestration. You can use a Web UI, Golang SDK or a hand-edit the JSON DSL to build your orchestration flows. Deploy as binaries/containers/functions or on a cloud service like TIBCO Cloud Integration.
Wow.. the product looks good and it's totally open I can choose between UI or coding.. I saw I can code in golang it would be cool be to be able to code in NodeJS as well thinking about AWS Lambda.. agregate different providers there like the Azure Functions and Google Functions.. all within your own Kubernetes. this is a very nice concept and seems like a great architecture. Loved the tip thanks!
