Can anyone familiar with it explain how it works and how to use it? I read Orchestra is going to be integrated into juju for easily setting up bare metal systems, so I'm assuming Orchestra works in a similar manner.
Basically, the Ubuntu orchestra server consist of the following components:
Cobbler is a Linux installation server that allows for rapid setup of network installation environments.
Nagios monitors large deployments to ensure systems, applications, services and business processes are functioning properly.
Juju was previously codenamed Ensemble. Through the use of charms, which describe services and their dependencies and interfaces, juju provides shareable, re-usable and repeatable expressions of DevOps best practices. Check out this Ubuntu Open Week Session for an intro to Juju.
Rsyslog is an enhanced syslogd supporting, among others, MySQL, PostgreSQL, failover log destinations, syslog/tcp, fine grain output format control, high precision timestamps, queued operations and the ability to filter on any message part.
