We host our application on Heroku. I'm wondering what can I do as a backup plan when Heroku doesn't work.
If I keep a backup of everything on Rackspace, when Heroku goes down, can I change to Rackspace in the moment? Any idea how that's done?
Thanks
Well, if everything works and is synced from Heroku to Rackspace (database and files) then you can just switch over.
Most fail-overs like this are done by changing the DNS record from your Heroku IP to your rackspace IP.
