Wikimedia servers and software make heavy use of clustering to simplify management of similar hosts and services. Currently this is done in a non-standardized, ad-hoc way however, which means that e.g. Ganglia, Nagios, Puppet, dsh etc. all use different category names. Because this will become even more important with the addition of a second primary data center, this page attempts to put some thought into standardizing it all.
Levels
We can distinguish at least the following levels in our infrastructure:
- sites
- (pmtpa and esams)
- physical locations
- (pmtpa, sdtpa, esams, knams)
- subnets (public subnet, squid-lvs subnet, internal subnet)
- host groups
- (cache servers, database servers, nameservers)
- service groups
- (mediawiki application, memcached, squid, mysql)
- further subdivisions
- (frontend squid)
