The [ec2 run script](https://github.com/metamx/druid/blob/master/examples/bin/run_ec2.sh), run_ec2.sh, is located at 'examples/bin' if you have checked out the code, or at the root of the project if you've downloaded a tarball. The scripts rely on the [Amazon EC2 API Tools](http://aws.amazon.com/developertools/351), and you will need to set three environment variables:

Realtime integration is intended to be extended in two ways:
1. Connect to data streams from varied systems ([Firehose](https://github.com/metamx/druid/blob/druid-0.6.3/realtime/src/main/java/com/metamx/druid/realtime/firehose/FirehoseFactory.java))
2. Adjust the publishing strategy to match your needs ([Plumber](https://github.com/metamx/druid/blob/druid-0.6.3/realtime/src/main/java/com/metamx/druid/realtime/plumber/PlumberSchool.java))

The expectations are that the former will be very common and something that users of Druid will do on a fairly regular basis. Most users will probably never have to deal with the latter form of customization. Indeed, we hope that all potential use cases can be packaged up as part of Druid proper without requiring proprietary customization.

#### Setting up Kafka
[KafkaFirehoseFactory](https://github.com/metamx/druid/blob/druid-0.6.3/realtime/src/main/java/com/metamx/druid/realtime/firehose/KafkaFirehoseFactory.java) is how druid communicates with Kafka. Using this [Firehose](Firehose.html) with the right configuration, we can import data into Druid in real-time without writing any code. To load data to a real-time node via Kafka, we'll first need to initialize Zookeeper and Kafka, and then configure and initialize a [Realtime](Realtime.html) node.
