be useful:
       For example, if deploying a MongoDB cluster then first focus on single-node MongoDB,
and then make that
       configurable and composable for a cluster.
     
    -* Use the test framework to write test cases, so that others can run these to confirm
that the 
    -  entity works in their environment.

     * Where appropriate, share the new entity with the Brooklyn community so that it can
be reviewed, 
       tested and improved by others in the community!

    +## Cloud Portability
    +
    +You get a lot of support out-of-the-box for deploying blueprints to different clouds.
The points 
    +below may also be of help:
    +
    +* Test (and regression test) on each target cloud.
    +
    +* Be aware that images on different clouds can be very different. For example, two CentOS
6.6 VMs 
    +  might have different pre-installed libraries, different default iptables or SE Linux
settings,
    +  different repos, different sudo configuration, etc.
    +
    +* Different clouds handle private and public IPs differently. One must be careful about
which 
    +  address to advertise to for use by other entities.
    +
    +* VMs on some clouds will not have a well-configured hostname (e.g. `ping $(hostname)`
can fail).
