Ghost blogs are automatically deployed and provisioned as separate node apps. They are then separated from each other, chroot'd and ran with pm2 (Node.js management software). The user then gets a system user which is given FTP access to their content directory where they can change themes, add images and backup their database. It is all running on SSDs in RAID for optimal performance. The client area also offers the ability to restart the Ghost blog.
What is 3942.pw? I'd probably stay away from using that in your marketing, it looks really spammy (all numbers, "weird" tld, tld I receive the most spam from at the moment)
Great to see more ghost blog hosting solutions come alive. I'm in love with the Ghost platform and want to see it thrive!
