At the moment, I have deployed my app on a single AWS instance with mupx, but I am facing problems with this. Once in a while (i.e. every 2-3 weeks), the server stops responding completely. Although the AWS console reports it as being OK, the server does does even react on SSH logon attempts any more. On mupx github, I was hinted that this might be a memory leak, but this is not sure at the moment.
I am still investigating this, but in order to prevent service abruptions for the future, I also want to set-up a fail-over scenario with a second machine that would take over if the main server is not reachable. Is there any good tutorial on how to do that in combination with mupx? I thought about integrating meteor cluster, but I don’t have any experiences with it yet, and I am open for all existing solutions out there. I would also appreciate any hints about things I have to take into account in my app once I implement a stand-by scenario. For instance, I heard that not all community packages are supporting this, and maybe I will have to adapt my app as well.
