Subject Re: what does cloudstack stateless means?

Hi, the CloudStack management server is "stateless" in that there is no
important configuration on the mgmt server, and everything is in the
database.  When your mgmt server fails, you can recover quickly by
installing CS on a new server and pointing it to the db (and probably a
few other steps).

For clients accessing the web UI, there is session data and clients
cannot switch between mgmt servers without logging in again.  The docs
hint to this in the load balancer configuration where it says
connections to mgmt servers should be sticky and not random.  If you are
using the API with API/secret keys, there is no session info and you can
switch between mgmt servers without a problem.

Best regards,
