Hi,
I loved the post, and added it to the end of my own post: https://medium.com/@eliezer/first-experiences-scaling-a-meteor-app-14a48e62a4af
One issue I think you need to mention about using Cloudflare is that it won’t work well with the ip_hash load balancing. We need to know the users IP address to make use of ip_hash load balancing and Cloudflare will hide this from us putting all our load on a single server. There was a way around this, but I can’t find the link for it online at this moment.
