I was using separate self-signed certificate for cluster authentication and SSL. Now I am deploying my application to a production environment. Can anyone suggest what approach I should follow for Production?
Is it possible to use my domain wildcard certificate for both cluster authentication as well as SSL?
It is certainly feasible to use the same cert. It should work normally on each - but do keep in mind that does mean that if the certificate is compromised it will compromise the security to both instead of just one or the other.
