Basically, and architecturally-speaking, I think I would need a PaaS layer above my existing IaaS layer. <br><br>I am interested in the following tasks:<br><br><div style="margin-left:40px;">*<span style="font-weight:bold;"> job distribution</span> among a set of dynamically created (or, as a start, fixed) VM's, initiated
by a master-VM<br></div><div style="margin-left:40px;">* <span style="font-weight:bold;">job execution</span> on the worker-VM's and, more importantly, <span style="font-weight:bold;">execution monitoring</span> of these jobs by the master-VM<br>* <span style="font-weight:bold;">results gathering </span>on the master-VM<br></div><br>I have briefly looked though Hadoop, which uses MapReduce, but, having no experience with it, I am not sure whether if it is the best tool to use for such a use-case, and also, I don't know if it could be at all used in my environment. So, my fundamental question is the following: which is the best way to start on, a way that would lead to satisfying my above-mentioned 3 necessities?<br>Is Hadoop perfectly compatible with OpenNebula, and could be used for such purposes, or are there other and more fitting solutions or tools to use? Basically, all I'm asking is, <span style="font-weight: bold;">what is the most appropriate
way for obtaining these basic GRID-computing functionalities on a Platform constructed above the Infrastructure?</span><br><br>Any suggestions, thoughts, and hints are extremely welcome, since this is a rather important and
urgent matter for me.<br><br>Thank you, <br>Lehel.<br><div style="margin-left:40px;"><br></div></td></tr></tbody></table></div></td></tr></table>
