The company I work for have 3000+ websites served from a single application. Whilst we offer everyone HTTPS when they log in (everything's on a subdomain at this point, so a wildcard cert does the trick), we don't have HTTPS enabled for general access to their websites. I've pushed for the 3000+ websites to be served over HTTPS but there's serious reluctance from the sys admins about creating and managing such volumes of certificates. So I'm guessing it's easy if you only have a handful of services, but at volume it becomes a little tricker. If there's a easy way to solve this problem, I'd love to hear it.
