TorqueBox - Like a JBoss - Philly RedSnake Talk

TorqueBoxLike a JBoss

What’s TorqueBox

• JRuby API around JBoss to:

• Run Ruby apps in JBoss AS

Who’s TorqueBox?

• Project built and supported by Red Hat

• #torquebox on IRC

• LGPL

• 5 years of active development

What’s JRuby

• Ruby on the JVM

• Not a toy

• Runs unmodified Ruby code

• Fast; Real Threads; Java Integration

What’s JBoss

Why JBoss?

• For an Ordinary Web Application

Why JBoss?

• For an Ordinary Web Application

• Just Run Passenger / Gunicorn

Why JBoss?

• Ordinary Web Application

• Just Run Passenger / Gunicorn

• And Memcached/Redis for caching

Why JBoss?

• Just Run Passenger / Gunicorn

• And Memcached/Redis for caching

• And Sidekiq/Celery for background jobs

Why JBoss?

• Ordinary Web Application

• Just Run Passenger / Gunicorn

• And Memcached/Redis for caching

• And Sidekiq/Celery for background jobs

• And Cron/Sidetiq for scheduled jobs

Why JBoss?• Ordinary Web Application

• And Memcached/Redis for caching

• And Sidekiq/Celery for background jobs

• And Cron/Sidetiq for scheduled jobs

• And EventMachine and Faye for Websockets

Why JBoss?• Ordinary Web Application

• Just Run Passenger / Gunicorn

• And Memcached/Redis for caching

• And Sidekiq/Celery for background jobs

• And Cron/Sidetiq for scheduled jobs

• And EventMachine and Faye for Websockets

• And a Load Balancer

Or

• Just Run JBoss

What’s in the Tin

• JBoss Web + Rack for running Web applications

• JBoss Web + Rack for running Web applications

• Infinispan for caching

What’s in the Tin

• Infinispan for caching

• HornetQ/JMS for messaging

• Quartz for scheduled events

• Stilts for STOMP messaging over Websockets

What’s in the Tin• JBoss Web + Rack for running Web applications

• Infinispan for caching

• HornetQ/JMS for messaging

• Quartz for scheduled events

• Stilts for STOMP messaging over Websockets

• mod_cluster/JGroups for clustering/load balancing

That’s a lot of stuff

• Can pick and choose

• But it’s all supported

• All within a single JVM, with JVMs clustered across nodes

Torquebox API

• Caching

• Messaging/Backgroundable

• Scheduled Jobs

• Services

• STOMP

Caching• Infinispan Data Grid

• Local memory

• Invalidate across cluster <- Rails Store Default

• Distributed <- Non-Rails Default, most interesting

• XA Transactions

• Configure Rails Cache Store for Torquebox

!

!

• Use the Rails.cache normally

!

Caching• Or Use TorqueBox’s Infinispan API directly

Messaging!

• HornetQ

• Load balancing, Failover, Timeouts, Retries

• Persistent across restarts

• TorqueBox API offers

• Topics (all subscribers get message)

• Queues (first subscriber to pop message gets it)

Topics vs Queues

• Configure a Topic at deployment

!

!

• Set up a class to process the messages

Backgroundable• Simpler abstraction for fire-and-forget

Scheduled Jobs

Services

• TorqueBox managed background thread

• Like a daemon

• Can run on a single-node with fail-over to another node in the cluster

WebSockets

• STOMP Protocol

• Ships with client JS library

• Can use Topics and Queues we saw earlier

Even More

• Authentication

• Hot deploys

• Dependency Injection

I wanna try this!• rvm install jruby

• gem install rails

• rails new your_app

• echo ‘gem torquebox’ >> Gemfile

• bundle install

• torqeubox run

• torquebox deploy

• OR

• docker run mguymon/torquebox

Backstage

• Dashboard monitor for your applications

• Deploys into Torquebox

Immutant

• Same thing for Clojure

• Red Hat’s Polyglot strategy

• Escalante for Scala

Rough Spots, IMO

• Clustering is non-trivial without multicast

• Logging

• Source is mostly Java

• JBoss configuration is intimidating

What’s Next

• Torquebox 4

• Probably Wildfly-based

• aka JBoss 8

• Improved Performance
