<div dir="ltr">Hi Antonio,<div><br></div><div>First of all, thank you for your contribution. I would like to share with you some comments ragarding this component.</div><div><br></div><div>In OpenNebula 4.2 we included the OneFlow [1] in the distribution. OneFlow allows users and administrators to define, execute and manage multi-tiered applications, or services composed of interconnected Virtual Machines with deployment dependencies between them. Each group of Virtual Machines is deployed and managed as a single entity. Maybe OneFlow can be used in your use case.</div>
<div><br></div><div>Now some comments about the implementation, I really like the way you integrated everything using the sunstone tabs, but I would try not to modify existing files of the OpenNebula distribution. We provide plugins in other parts of the stack to avoid modifying existing files, not only in the sunstone tabs, for example:</div>
<div><br></div><div>* In VirtualClusterJSON.rb you are interacting directly with the OpenNebula DB, but the only component interacting with the DB should be oned. For this, we provide the DOCUMENT resource, this will allow you to use OpenNebula as a DB and use all the OpenNebula permissions system, you just have to define a DOCUMENT_TYPE for your resource. More information</div>
<div> * <a href="http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/Document.html">http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/Document.html</a><br></div><div> * <a href="http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentPool.html">http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentPool.html</a></div>
<div>and the DocumentJson subclass that uses this class to store JSON objects:</div><div> * <a href="http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentJSON.html">http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentJSON.html</a></div>

* Instead of modifying the SunstoneServer.rb, you can use the Sunstone server plugins to add custom routes to the server:</div><div> * <a href="http://opennebula.org/documentation:rel4.2:sunstone_server_plugin_guide">http://opennebula.org/documentation:rel4.2:sunstone_server_plugin_guide</a></div>

<div><br></div><div>Maybe this information is not clear in the documentation, I just wanted to let you know about these features. This will allow you to integrate this component without modifying any of the existing OpenNebula files.</div>
<div><br></div><div>If you have any doubts please do not hesitate to ask us.</div><div><br></div><div>Cheers</div><div><br></div><div>[1] <a href="http://opennebula.org/documentation:rel4.2:oneapps_overview">http://opennebula.org/documentation:rel4.2:oneapps_overview</a></div>
