Hi Anoop, This is great and really valuable information, thank you. .
I'd heard that CloudFlare use a variant of Nginx for providing SSL termination which was why I was hopefully that it would be able to manage our use case.

Memory consumption by worker process go up when vhost count go up , so we may need to reduce worker count 2. As already mentioned the reload might take a lot of time ,so do nginx -t 3. Even startup will take time as most package maintainers put a nginx -t on ExecPre(similar in non-systemd) which take a lot of time on startup I have read somewhere, Nginx is not good at handling this many vhost defs ,so they use a dynamic setup (like the one in OpenResty) at CloudFlare edge servers for SSL On Tue, Feb 12, 2019 at 1:25 AM Peter Booth via nginx <nginx@nginx.org<mailto:nginx@nginx.org>> wrote: +1 to the openresty suggestion I’ve found that whenever I want to do something gnarly or perverse with nginx, openresty helps me do it in a way that’s maintainable and with any ugliness minimized. It’s like nginx with super-powers!

That's great to hear, as we'd only get to find this out after putting rather a lot of effort into the process. We'll be hosting these on cloud instances but since those aren't the fastest machines around I'll take the reloading as a word of caution (we're probably going to have to make another bit of application functionality which will handle this so that we're only reloading when we have domain changes rather than on a regular schedule that'd I'd thought would be the simplest method.) I have a plan for the rate limits, but thank you for mentioning it. SANs would reduce the number of vhosts, but I'm not sure about the added complexity of managing the vhost templates and the key/cert naming.

Reloading can take up to a minute but the Hardware isn't what I would call recent. The only thing that you'll have to watch out are Letsencrypt rate Limits > https://letsencrypt.org/docs/rate-limits/ ##### /etc/letsencrypt/renewal $ ls | wc -l 1647 ##### We switched to using SAN Certs whenever possible. Around 8 years ago I managed a 8000 vHosts Webfarm with a apache. No Issues ether.

Great ... for us. However, our customers, with about 12000 domain names at present have started to become quite vocal about having HTTPS on their websites, to which we provide a custom CMS and website package, which means we're about to create a new Nginx layer in front of our current servers to terminate TLS. This will require us to set up vhosts for each certificate issued with server names which match what's in the certificate's SAN. To keep this simple we're currently thinking about just having each domain, and www subdomain, on its own certificate (LetsEncrypt) and vhost but that is going to lead, approximately, to the number of vhosts mentioned in the subject line. As such I wanted to put the feelers out to see if anyone else had tried to work with large numbers of vhosts and any issues which they may have come across.
