+title: YAML BLueprint Advanced Example
+layout: website-normal
+---
+
+By this point you should be familiar with the fundamental concepts behind
both Apache Brooklyn and YAML blueprints. This section of the documentation is
intended to show a complete, advanced example of a YAML blueprint.
+
+The intention is that this example is used to learn the more in-depth
concepts, but also to serve as a reference point when writing your own
blueprints. This page will first exaplin what the example is and how to run it,
then it will spotlight interesting features.
+
+
+### The Example
+
+The example itself is a deployment of an ELK stack. ELK stands for
Elasticsearch, Logstash and Kibana- and this blueprint deploys, installs, runs
and manages all three. Briefly, the component parts are:
+
+* Elasticsearch: A clustered search engine
+* Logstash: Collects, parses and stores logs. For our application it will
store logs in Elasticsearch
+* Kibana: A front end to Elasticsearch
+
+For more about the ELK stack, please see the documentation
[here](https://www.elastic.co/webinars/introduction-elk-stack).
+
+In our example, we will be creating the ELK stack, and a Tomcat8 server
which sends its logs using Logstash to Elasticsearch.
+
+#### The Blueprints
+-----------
+
+There are four blueprints that make up this application. Each of them are
used to add one or more catalog items to Brooklyn. You can find them below:
+
+* [Elasticsearch](example_yaml/brooklyn-elasticsearch-catalog.bom)
+* [Logstash](example_yaml/brooklyn-logstash-catalog.bom)
+* [Kibana](example_yaml/brooklyn-kibana-catalog.bom)
+* [ELK](example_yaml/brooklyn-elk-catalog.bom)
+
+#### Running the example
+First, add all four blueprints to the Brooklyn Catalog. This can be done
by clicking the 'Catalog' tab, clinking the '+' symbol and pasting the YAML.
Once this is done , click the 'Application' then the '+' button to bring up the
add application wizard. A new Catalog item will be available called 'ELK
Stack'. Using the add application wizard, you should be able to deploy an ELK
stack to a location of your choosing.
