== Thomas-Krenn.AG ==
[http://www.thomas-krenn.com/ Thomas-Krenn.AG] is a server specialist, selling server systems and solutions. One of the solution products is a pre-installed [http://www.thomas-krenn.com/en/system-solutions/ha-linux-cluster.html cluster system], built with Virtuozzo. They published how to build such a cluster with OpenVZ at [[HA cluster with DRBD and Heartbeat]].
== Unixservice ==
[http://www.unixservice.com/ Unixservice] provides SLAs for critical internet infrastructure provisioning. As we have grown over the past 10 years we have become fervent advocates of running such services on a grid/cluster of OpenVZ (or Virtuozzo) servers. The main R&D team leader has just released our own C based unxsVZ grid/cluster manager (unxsVZ) released under a GPL license, including [http://openisp.net/openisp/unxsVZ/wiki/UBCAutonomics autonomic functions] that we have developed based on discrete mathematics and CMU/IBM research. [http://openisp.net/openisp/unxsVZ unxsVZ source, yum repository and RPMs here.] Call us now with questions; we even provide free deployment support and container tuning support for DNS/BIND, RADIUS, HTTP Apache hosting, ESMTP stores, ESMTP out and MX edge server farms on large VZ grids.
