Hi I have a question about deployment, if it's not the right place, please let me know.
So would like my application to be HA with load balancing which I can found guide here.
I thing that confuse me is on deployment, when you do a deploy on domain with HA, during the deployment, is the server still available to public? How is the deployment roll out internally?
Ideally I would like it to be - when deploy to domain, the controller deploy to one server while other is still available. Is it possible with the guide above? Or should I better use 2 standalone server?
If the servers are in the same server-group both will be affected by deployment and might not respond for a while.
You might separate it to two server groups with the same configuration, here you are able to shutdown or deploy one groups which is removed from the mod-cluster loadbalancing.
AFAIR the gracefull shutdown feature (WildFly 10) will cover this better.
