At Omnis, we are specialized in the management of dedicated and shared UNIX servers. We use self-developped software and tools (some of them are open-source) to manage all parts of the system operation: domain management, DNS management, backups, administration, security.
Some possibilities:
- LAMP/FAMP Server (Linux or FreeBSD Apache + Mysql + PHP/Perl/Python/Ruby)
- Ruby on Rails 3 (mod_passenger)
- Mail Server (qmail, postfix, with antispam/antivirus)
- Database systems, with single-server or multiple-server operation (with replication for High-Availability or Load Balancing)
- File Server
- Network gateway / Firewalls
