Deploying Rails App

Deploying Rails App Personal notes on rails deployment Mayank Sharma http://www.revu.in

Disclaimer
Random bits of learning from my Rails hacking.

Rails Deployment
Self hosting (Amazon/Rackspace)
Install all packages your self
Fine tune the system for caching/DB access/Load balancing etc...
Full independece at the cost of shifting focus from what you should really be doing (development)
Managed Hosting (Heroku/Engineyard)
Forget sysadmin to people who do it best.
Faster deployment and truly scale to your requirements.

Deployment on Heroku
Just 4 steps to create and launch your application online.
Deployment as simple as a git push.
Free account is just about enough for your validations.

Why I Like Heroku
Provides highly optimized bare bones Rails stack
Takes care of caching and load balancing on its own.
Uses git as a way of deployment, hence no other deployment framework has to be learnt.
Feels like deploying on your m/c. No code replication (atleast not in your control)
The basic free plan is just enough for a quick prototype.

Scaling the Cloud way
DB heavy app? Just add a dedicated DB server
Too many hits? Use eternal caching or just increase the number of threads.
Pay exactly for what you need and nothing more and scale in real time.
Basically forget architecturing your app and focus only on development.
Love ruby for gems? You will love Heroku for Add-ons.

Heroku's Architecture
Multi-Tenant (Controversial but works)
Fully Managed (DB/HTTP/Rails stack)
Dyno Grid (Scale as you grow)
Amazing HTTP Caching (Varnish)
A must study for web app architectures

Deployment in Action
Revu is a social micro-review and recommendation site.
Uses your existing social network on Facebook/Twitter.
Allows submission over SMS and auto-publish to FB/Twitter
Works on just 15$ a month on Heroku.
