Building Distributed Systems with Node.js and ØMQ
=============
VIDEO! [Building Distributed Systems with Node.js and ØMQ](https://www.youtube.com/watch?v=zgDjaJdAB9c)
A talk for [Node.js in the Wild](http://www.meetup.com/Node-js-in-the-wild/events/188786272/)

## Talk Roadmap
* Why ØMQ?
* Installing ØMQ (skip)
* Naive publish/subscribe using Sockets
* PUB/SUB
* REQ/REP
* DEALER/ROUTER
* PUSH/PULL
* Questions?
## Why ØMQ?
* Distributed
* Low latency, low-overhead
* Event driven, non-blocking
* Patterns!
* Scalability / Philosophy of Ø
## The Network Onion
* Application, Presentation, Session
* SSL, HTTP, SMTP, ØMQ
* Transport --- TCP, UDP
* Network --- IP
* Data Link --- MAC
* Physical --- wires
## Installing ØMQ
Mac OSX
```sh
brew install zmq
```
Ubuntu
```sh
sudo apt-get install libtool autoconf automake uuid-dev build-essential
wget http://download.zeromq.org/zeromq-3.2.2.tar.gz
tar zxvf zeromq-3.2.2.tar.gz && cd zeromq-3.2.2
./configure
make
sudo make install
```
Testing the base library.
```sh
man zmq
```
Install the zmq node module.
```sh
npm install zmq
```
Testing the module.
```sh
node --harmony -p -e 'require("zmq")'
```
First pass at troubleshooting (update system library cache):
```sh
sudo ldconfig
```
## Naive PUB/SUB with Sockets
Beacon application: fires an event once a second.
```js
{
"pid": 12345,
"timestamp": 1404168475695
}
```
PUB program: [net-beacon-pub.js](net-beacon-pub.js)
SUB program: [net-beacon-sub.js](net-beacon-sub.js)
## What's Wrong With That?
* Listener bias.
* Fault intolerant.
* Leaky buffers.
* Directionality (Publisher = Listener).
## PUB/SUB with ØMQ
Same beacon application.
PUB program: [zmq-beacon-pub.js](zmq-beacon-pub.js)
SUB program: [zmq-beacon-sub.js](zmq-beacon-sub.js)
## REQ/REP with ØMQ
Application requests the current time.
REP program: [zmq-time-rep.js](zmq-time-rep.js)
REQ program: [zmq-time-req.js](zmq-time-req.js)
## DEALER/ROUTER cluster with ØMQ
DEALER = parallel REQ
ROUTER = parallel REP
Cluster responds to time requests just like the previous example.
REP cluster program: [zmq-time-rep-cluster.js](zmq-time-rep-cluster.js)
## PUSH/PULL with ZMQ
Simple work queue using PUSH/PULL.
PUSH program: [zmq-work-push.js](zmq-work-push.js)
PULL program: [zmq-work-pull.js](zmq-work-pull.js)
Cluster to demonstrate the First Joiner problem.
PULL cluster program: [zmq-work-pull-cluster.js](zmq-work-pull-cluster.js)
## Wrap Up
* Why ØMQ?
* PUB/SUB
* REQ/REP
* DEALER/ROUTER
* PUSH/PULL
## Thank You!
For your kind attention.
## Questions?
