Single Source of Truth


Scribe: Lucas Yamanishi

* Many sources of truth can lie * Some truths are inherantly distributed * New sources of truth grow organicly * Querying machines over and over can be wasteful


  • Google Image Search can be useful for finding reference architecture diagrams
  • Sometimes it's better to not track a truth than to track it in a central DB
  • Audit logs! They record information as it happens, including changes. Query them for a snapshot of truth.
  • Remove the human aspect
  • Everybody in an organization should be able to update their portion of the data
  • The "single source" needs to be modular

Software products:

  • Racktables
  • Hiera
  • DNS
  • Collins (from Tumblr)
  • ElasticSearch
  • OSQuery
