I’ve seen a few various posts searching through the forum/blogs about how large of deployments people are supporting. There hasn’t been one in a couple of years though and I feel like there have been a lot of changes in Foreman since then. Are there large deployments of Foreman being used still? The most I’ve seen was the HA scaling blog post mentioning 45k servers.
People keeps using it for large deployments. At the end of the day nothing changed. you can scale up to your hardware+smart-proxy limits.
