[SR-Users] [ot] virtualization systems

[Carsten Bock]

Hi Daniel,

here's from my personal experience:
Our setup at ng-voice is a little weird sometimes: We've rented some
virtual servers at a german provider (who uses Xen). On these virtual
servers we've installed OpenVz, which for us is absolutely great, if
you are just working with Linux-Servers. While Xen is a rather
complete virtualization, OpenVz is lightweight and comes in handy, if
you just want to logically separate servers. We've got each IMS
component (P-/I-/S-CSCF, HSS, Application-Servers, Databases) running
on a dedicated OpenVz Container, which is really great. We've even got
a CentOs-Container running on a Debian OpenVz, which is started
"on-demand" in order to build RPM-Packages. With OpenVz you can even
move Containers from one host to another, theoretically with zero
downtime (doesn't work with SEMS, don't know about other software).
For our IMS-setup, we work with RTP-Relaying, which works great within
virtualization, i cannot complain.

At another customer (a fibre provider in Germany), we're running all
the infrastructure on Xen-only. An infrastructure provider takes care
of the administration, but those servers run poorly (RTP-Relaying is
okay but everything else is really slow).

Conclusion for me: VoIP on virtual servers can work great, but the
virtualization infrastructure needs to be administered properly which
may not be an easy task, if you are new in this subject.

Kind regards,
Carsten
