TorqueBox from Dec. 2011 URUG

Transcript

1. There’s Javas in my rubies!

2. What is TorqueBox? A JVM-based, prepackaged server stack for JRuby

   Rack apps (Sinatra, Rails, ...): Web application server (JBoss), Messaging (HornetQ), Services (like Daemons), Scheduling (like Cron), designed for scalability & availability

3. Our problem (corner case): Oracle + Ruby = :-( Oracle

   + JDBC = :-)

4. More problems (typical): • Scalability • High availability • Complex

   server stack • Distribution of caching, sessions, etc. • Much easier to scale up than out

5. O HAI JVM • 1st Class JDBC drivers • Concurrency

   via real threads • Fast! • It’s real Ruby

6. What’s wrong with Ruby on JVM? • WAR files break

   continuous deployment and require server restarts • Increases server stack complexity • XML hell • Fewer people doing it = less support

7. Enter TorqueBox YAML config (the NoXML) Hot Redeploys (no restarts!)

   Streamlined server setup & monitoring Easy Deployment (cap deploy) Baked-in high-scalability & availability Great community & support (Red Hat)

8. Tech Stack

9. Tech Stack (simpler)

10. Tech Stack: JBoss AS Tech Stack: JBoss AS

11. Tech Stack: JBoss AS Multi-app friendly Load Balancing Clustering High

    Availability Rock solid

12. Tech Stack: JBoss AS Tech Stack: Infinispan

13. Tech Stack: Infinispan Cache Sessions Or use it as a

    DataMapper clustered NoSQL store

14. Tech Stack: HornetQ

15. Tech Stack: HornetQ Set up queues via YAML: messaging: /queues/puppies:

    MyHandler: concurrency: 5 config: some_key: some_value Or at runtime: @queue = TorqueBox::Messaging::Queue.new("/queue/foo") @queue.publish( “Oh, puppies!” )

16. Tech Stack: HornetQ Crazy fast Optionally durable Backgroundable: include TorqueBox::Backgroundable

    always_background :do_something_slowly

17. Tech Stack: Scheduled Jobs It’s not cron! Configure via YAML

    JGroups runs tasks on all nodes or as singleton # config/torquebox.yml jobs: monthly_reminder: description: sends reminders job: MyJob cron: ‘0 0 0 1 * ?’ singleton: true # app/jobs/my_job.rb class MyJob def run() # your code here end end

18. Tech Stack: Services Daemon-like Easy to monitor JGroups: All nodes,

    single-node, failover # app/services/my_service.rb class MyServer def initialize(opts) end def start end def stop end end

19. Tech Stack: Backstage

20. Tech Stack: Backstage Sinatra app for centralized monitoring Manage entire

    stack from one view

21. Oh my gosh so much more Capistrano support (or archive

    deploy, or web-based git deploy in StompBox) Meta-transactions (incl. ActiveRecord, queue, Infinispan) Client-side async with Stomplets RSpec helpers

22. Challenges Slow-ish boot time for dev Larger base memory footprint

    Ruby 1.9 is “edge” “The TorqueBox Way”: Bundled stack is largely what you get If using advanced features (like messaging), you need to develop against TorqueBox, not ‘rails s’
