re: Migrating Rails Apps to VPS - worth it? VIEW POST

FULL DISCUSSION
 

Can't tell you much about running rails apps in parallel, but I'd guess that's probably the easier part anyway. If you're ok with using nginx, you can easily configure 5 server blocks, each with their own server_name (the subdomain) that reverse proxies to the rails instance either through localhost or unix domain sockets (no idea if rails supports those). From there you can use nginx to gzip data, handle https for all of your apps in one place, do some caching, take care of server-push, etc. Overall a good option if you want scalability. If you're feeling adventurous, I'd suggest going with openresty instead of vanilla nginx; the added benefit of lua scripting comes with almost no cost and may allow for some easier customization.
