I am using AWS step function and I made some changes in state machine and activity worker. Activity code changes are not backward compatible. Also, activity code is deployed in my hosts (not hosted in AWS Lambda).
I saw some examples online to follow Blue-Green deplopyment: https://theburningmonk.com/2019/08/how-to-do-blue-green-deployment-for-step-functions/
But I am not using AWS Lambda, so what are the ways I can deploy my changes which are not backward compatible. How to do blue green deployment in aws step function when activites are hosted in non-AWS hosts.
