Dear
all,
After having successfully set up a small-scale (but
up-and-running) experimental Private Cloud (using OpenSUSE 12.1 64bit
machines -also VM's-, KVM as hypervisor, and ONE 3.2.0), my next task is
to find a way in which GRID-like services (see below) could be
implemented inside an OpenNebula-based Cloud. Basically, and
architecturally-speaking, I think I would need a PaaS layer above my
existing IaaS layer.
I am interested in the following tasks:
* job distribution among a set of dynamically created (or, as a start, fixed)
VM's, initiated
by a master-VM
* job execution on the worker-VM's and, more importantly, execution monitoring
of these jobs by the master-VM
* results gathering on the master-VM
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?
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, what is
the most appropriate
way for obtaining these basic GRID-computing functionalities on a Platform
constructed above the Infrastructure?
Any suggestions, thoughts, and hints are extremely welcome, since this is a
rather important and
urgent matter for me.
Thank you,
Lehel.
