Hi
My $0.02 coming from experience building out scalable WP clusters is,
stick to Varnish here.
Miscommunication on my part -- my aforementioned Varnish-in-front
referred to site dev in general.
To date, it's been in front of Symfony sites. Works like a champ there.
Since you're apparently working with WP under real-world loads, do you
perchance have a production-ready, V6-compatible VCL & nginx config you
can share? or point to?
FRiCKLE's module is great, but it would be scary to put into production-
have fun with that test/release cycle :p
Yep. Hence my question(s)!
The overhead of putting Nginx in front of Varnish is fairly small in the
grand scheme of things. What's your motivation to strictly use Nginx?
This time 'round, it's not entirely 'my' motivation; came with the job's
"prefer to haves".
Based, in apparently large part, on the usual use of TheGoogle; these 2
in particular:
https://deliciousbrains.com/page-caching-varnish-vs-nginx-fastcgi-cache-2018/
https://www.scalescale.com/tips/nginx/nginx-vs-varnish/
There is official support for cache purging with the commercial version
of Nginx: https://www.nginx.com/products/nginx/caching/.
Ah, so not (yet) in the FOSS product. I see it's proxy_cache, not
fastcgi_cache, based ...
I've seen moderate hardware running Nginx (for TLS offload + WAF) ->
Varnish (cache + purge) -> Apache/mod_php do 50k r/s on a single node.
One would hope this suffices; it's a stable and proven stack. Again,
ngx_cache_purge is great, but any unsupported module in a prod
environment is scary when you're not writing the code. ;)
Again, yep.
Thx!
