Team,
We are using hybris roll out that allow us hybris deployment without any outage. That's good but now next goal is graceful scale down of server in a way that customer in checkout process are not impacted at all. It means if a customer is in middle of checkout on a server that we want to bring down for deployment then server will wait either for completion of transaction or a defined time. During this time it won't allow new http session too.
Unfortunately our load balance does not support http session graceful scale down/session drainage functionality. Now I am looking for other compenents of the architecture and it seems it can be achieved through web server (nginx) or app server(tomcat) cluster.
Have you done this earlier, If yes, please share your learning/thoughts around this?
Tomcat 7 introduces what is called Parallel Deployment, has anyone tried it with Hybris 5.4.x?
