An introduction to painless deployment
Motivation
A Rails philosophy:convention over
configuration
Convention over configuration for
deployment?
Good opportunity for our first product!
Our version of“Hello World” as an
IT company.
Phusion PassengerAct 1
“Short intro”
Suitable for exotic setups as well
Initial responses
Lots of attention!
Pleasantly surprised!
Impressed!
Ugh, FUD
Acceptance of Rails
“Rails is less used than PHP”, how come?
“PHP gets the job done,so why learn Rails?”
Cause the right tool for the job you must use!
“Everybody knows PHP”
No scarcity of PHP devs
Rails devs on the other hand?
Rails marketshare needs devs to grow,
while other devs reluctant to do Rails
Economic deadlock!
Most hosts don’t support Rails
this could lead to“PHP rocks, Rails
sucks”
Why should I care?
You’re part of the market as well!
Phusion Passenger saves the day?
Well, let’s see...
Most hosts use Apache
Ease of use matters!
Time == Money
Robustness matters
Stability matters
Should perform well
Everyone can help!
Commercial support
The big guys are excited!
"Apple is excited about Phusion Passenger as a convenient way to deploy Ruby on Rails
applications, complementary to Mongrel and mod_proxy_balancer.
We look forward to working with Phusion to ensure great Mac OS X support going
forward."
Ernest N. Prabhakar, Ph.D.Open Source Product Manager
Apple, Inc.
Phusion Passenger saves the day?
Never gonna give up ;-)

In this case, every N request is unresponsive
Solution?
Forward request to Rails instance with least

• Copy-on-write optimization to the garbage collector of MRI
• Transparent solution
• Ease of use
• A solution for today’s performance and memory use problems with Ruby
A copy-on-whah?
Example
String A = “foo”;String B = A;
Example
String A = “foo”;String B = A;
A and B refer to the same memory
Memory Management Heuristic
A
B
“foo”
Only useful if there are no side effects!
Example
String A = “foo”;String B = A;
Let’s write to ‘A’
Example
String A = “foo”;String B = A;A.append(“bar”);
Apply Copy on Write
A
B
“foo”
Copying on write
A
B
“foo”
“foo”
Situation after Copy on Write has been applied

No redundancy in memory use!

Great numbers, got case studies?
At iLike we've been testing Passenger in production, and we're
very impressed. This has the potential to reduce our memory
requirements by 25 - 50%

Questions & Answers
Will Phusion Passenger support Rack?
Fabio Akita
No, it WILL not...
Because it ALREADY supports Rack!
Screencast 2.0Return of the Ryan
mod_rails is dead
So, mod_rack is it?
NO!
We want Leah Culver!
She does Python...
So Phusion Passenger also supports WSGI!
What does this imply?
It starts with a ‘d’ and ends with ‘ango’.
No, not Dyango ;-)
Say hello to my little friend!
Why?!
Because we can!
Feel free to tinker with the code yourself! :-)
