Delivering Autonomous Rails Apps behind Corporate Firewalls
summary
Packages a Rails SaaS into an on‑prem VM and proves a deployable prototype: an 800MB–1GB VM, a 50–100MB vendored app tarball and a per‑customer encrypted license. Uses VirtualBox/OVA for distribution, Passenger + Sinatra loader to extract and hot‑restart, gibberish/OpenSSL for license encryption, vendor bundle for gems, pg_dump/pg_restore for data migration and foreman/upstart for background jobs. Implements seat‑based licensing, encrypted support archives and basic obfuscation; the prototype succeeds at installation, updates and offline licensing.
