    +## A Clustered Example
    +
    +We'll now look at a more complex example that better shows the capabilities of Brooklyn.

    +
    +We'll start by deploying an application via YAML blueprint consisting of the following
layers.
    +
    +- A dynamically scalable Web App Cluster
    +- A MySQL DB
    +
    +
    +Copy the blueprint below into a text file, "mycluster.yaml", in your workspace, but *before*
you create an application 
    +with it, again modify the YAML to specify the location where the application will be
deployed.  
    +You will need at least five machines for this example, one for the DB, and four for the
tomcats 
    +(but you can reduce this by changing the "maxPoolSize" below.
    +
    +{% highlight yaml %}
    +name: cluster
    +

    +  tbd

    This is a cut-and-paste error, it shouldn't have a location at all.
